Do banks accept electronic signatures? Learn where they are valid, what documents still require wet signatures, and how banks keep them secure.

The answer to the question, “Do banks accept electronic signatures?” is yes, as they are recognized by many financial institutions now and are used for various types of transactions. Since the banking industry adapts to modern, digital-first trends, too, it is no wonder electronic signatures have an important place in their systems.

This guide allows you to take a closer look at the legal background, security standards, and benefits and limitations of using electronic signatures in banking. Additionally, we will show you how to sign documents electronically with trusted tools like PDF.net.

Banks’ acceptance of electronic signatures is influenced by the ESIGN Act, UETA, ESRA, and FFIEC. Regulations like the KYC and AML also play a role.

Banks that have digital signature policies include JPMorgan Chase, Bank of America, Wells Fargo, SoFi, and Ally.

E-signatures can be used for account opening and lending. Wet signatures are required for promissory notes, notarized documents, and collateral documents like mortgages.

Banks implement many security measures for e-signatures, like assessing risk, implementing layered security, and safeguarding email systems.

E-signatures reduce costs and improve customer experience. However, they often come with compliance challenges, security concerns, and technological barriers.

The Legal Foundation of Electronic Signatures in Banking

In addition to knowing the answer to “Do banks accept electronic signatures?” it helps to understand the laws surrounding e-signatures and how courts view their validity in financial documents.

Federal Laws That Govern Electronic Signatures

In the U.S., electronic signatures are governed by the Electronic Signatures in Global and National Commerce Act (ESIGN), the Uniform Electronic Transactions Act (UETA), and the Federal Financial Institutions Examination Council (FFIEC).

 is a federal law that establishes the legal validity of electronic signatures

for transactions in or affecting interstate or foreign commerce. It was enacted in 2000 and provides that 

electronic signatures carry the same legal weight

 as handwritten signatures as long as certain requirements are met. These include obtaining consent from all parties and ensuring the electronic signature can be accurately reproduced.

 is a model state law that has been adopted by 49 states (New York being the exception).

It offers more detailed provisions for electronic transactions at the state level

and is combined with the ESIGN Act to create a comprehensive framework.

New York has not adopted UETA; however, since 2000, it has operated under the 

Electronic Signatures and Records Act (ESRA)

, which provides legal recognition for electronic signatures and records.

 is an interagency body that issues examination guidance for financial institutions regarding electronic banking services. Its guidance helps banks implement electronic signature processes that meet regulatory expectations to protect both the consumers and the institutions.

Together, ESIGN, UETA, and FFIEC allow banks to accept electronic signatures while providing customers with secure digital transaction capabilities.

Banking Regulations and Compliance Requirements

banks must follow the FFIEC’s requirements

 to identify all users, systems, and digital banking services that require authentication. They must also implement multi-layered security, like continuous monitoring of authentication systems.

They must also comply with Know Your Customer (KYC) guidelines, which verify the identity, suitability, and risks involved with maintaining a business relationship with a customer. The KYC process includes ID card verification, face verification, and biometric verification.

 requires financial institutions to develop and maintain a KYC/AML program. Meanwhile, Anti-Money Laundering (AML) regulations help prevent financial crimes and limit the flow of illegal money into the financial system.

KYC verification is a requirement for AML measures

, with regulations becoming increasingly strict for not just banks but also credit unions, credit card companies, and fintechs. Electronic signature systems must meet audit trail, transaction monitoring, and documentation standards that support AML compliance.

So, are electronic signatures legally binding? The answer is usually yes; e-signatures are typically considered valid evidence in court, using the same criteria as traditional signatures. 

Courts can’t invalidate e-signatures solely because they are in electronic form, as long as they meet the established requirements through ESIGN and UETA.

There are no publicly available banking-specific electronic signature court cases. However, federal and state laws provide a clear precedent for e-signatures’ validity in financial transactions:

Both parties must agree to conduct business electronically

An e-signature must be clearly associated with the person who has signed the document.

The person signing must be informed that they have the right to obtain paper versions of electronically signed documents and to withdraw consent.

Disclosures must also include instructions on how to obtain paper records and the hardware and software requirements needed to access electronic records.

 an electronic signature is only legally binding if it includes an audit trail

, which must note details like when the signing took place and who initiated it. The system must be able to prove that the e-signature is connected to the signed document and that the document has not been tampered with after signing.

Which Banks Accept Electronic Signatures, and for What Documents?

Electronic signatures are increasingly accepted by banks and supported by a robust legal framework. Financial institutions rely on this framework to 

Major Banks Leading the Digital Transformation

JPMorgan Chase, Bank of America, and Wells Fargo

, have integrated e-signatures into their digital banking platforms. Additionally, online-only banks and digital-first financial institutions, like 

, have also adopted electronic signature systems as part of their operating model.

Banking Documents You Can Sign Electronically

Banks that have accepted electronic signatures implement them across multiple document types to streamline customer transactions. Therefore, e-signatures are commonly used for 

account opening, lending, and modifying existing agreements

, like loan deferrals and forbearance requests.

In account opening, specific documents might include account opening applications, consent forms, and terms and conditions. Meanwhile, in lending, these could be loan agreements, underwriting documents, broker contracts, and credit score disclosures.

Documents That Still Require Traditional Signatures

 in banking has been significantly reduced, but there are still exceptions based on regulatory requirements and institutional policies. So, when can you not use an electronic signature, and what contracts cannot be signed electronically?​​

 (unless they meet transferable record standards),

 like mortgages, deeds of trust, and other agreements that require filing with government registries

5 Security Measures Banks Use for Electronic Signatures

To tell if a signature is electronic and protect customer identities and sensitive financial data, banks adopt a range of security measures. These are part of a broader framework that ensures both compliance and resilience.

Here are the main security strategies outlined by 

Risk assessments identify threats, vulnerabilities, and the effectiveness of existing controls. For electronic signatures, these usually include:

Listing all digital banking platforms and services

Pinpointing users who engage in high-risk transactions

Recognizing threats such as malware, phishing, and credential abuse

Regularly reviewing the performance and configuration of access controls

Instead of relying on a single method of protection, banks that accept electronic signatures have layered security methods to ensure electronic signatures are safe. These can include:

. Using a combination of factors like passwords, one-time codes, cryptographic keys, or biometrics

. Removing unnecessary services and tightening system configurations

. Automatically logging out inactive users and capping high-risk transaction amounts

Each layer adds a checkpoint, making it harder for unauthorized users to breach the system.

Banks have monitoring tools that track all activity related to electronic signatures, and they generate logs for system access, user actions, and completed transactions. These logs help:

Detect unusual behavior early and investigate it immediately

Reconstruct events with audit trails when there are security incidents

Identify who performed which action, which reduces internal fraud

With detailed records, financial institutions ensure that their digital platforms are traceable and trustworthy.

#4. Safeguarding Email Systems & Internet Browsers

Threat actors often exploit email systems and browsers to steal credentials or intercept e-signature flows. To counteract the risks of electronic signatures, banks:

. Implementing MFA, safe email configurations, and regular user training

. Blocking pop-ups, limiting scripts, and disabling unnecessary features

 and malware that could otherwise compromise the integrity of electronic signatures.

To ensure you do not have to worry about whether someone can use your e-signature, banks implement strong identity verification. Typically, this includes:

. Checking documents and identities against databases

. Identifying synthetic identities or impersonation attempts

. Following the USA PATRIOT Act's customer identification program (CIP) requirements, such as maintaining records of the information used to verify a customer’s identity

Banks use biometric or document-based verification in addition to knowledge-based authentication to make it difficult for attackers to bypass.

Benefits and Limitations of Electronic Signatures in Banking

Now that you know the answer to “Do banks accept electronic signatures?” you should grasp the advantages and disadvantages of this option.

e-signatures help streamline processes and save on expenses

. Transactions can be completed in minutes, and there are lower chances for manual errors or delays. Plus, it is possible to save on costs related to using paper, printing, mailing, and storing documents. As a result, banks can enjoy better profitability over time.

For customers, there is no need to step into a bank to sign documents, which saves time, money, and effort. It also 

makes banking more accessible and appealing

, which ultimately strengthens customer satisfaction.

However, there are still regional regulations that can complicate the implementation of e-signatures in banking. 

Banks need to carefully navigate these to avoid falling foul

. There are also online threats that banks need to guard themselves against, e.g., phishing and malware, where a single breach can severely damage a bank’s credibility.

Furthermore, adopting an electronic signature system can be costly

, especially for smaller banks, because it requires investment in both the technology and the training. Banks that are not already digital-first have to merge new solutions with old systems, and this can be quite resource-intensive.

A PDF signature is legally valid in most situations, making it a practical solution for signing everything from forms to contracts. But beyond just being valid, 

 should be simple, secure, and accessible, and that is where PDF.net delivers.

You can upload files in DOC, DOCX, JPG, or PNG formats, convert them to PDF on the spot, and 

PDF.net also offers helpful tools like form field editing and multi-party signing. And to protect your e-signature, all files are automatically deleted after processing.

You now know that the answer to "Do banks accept electronic signatures?" is yes. 

Under the ESIGN Act and UETA, most banks allow you to electronically sign documents

 to process account openings, lending, and modifications of existing agreements.

However, there are still some cases where you will need to provide wet signatures

, like signing promissory notes. So, it is essential to stay informed. Use a trusted tool like PDF.net when you need to sign documents digitally and manage them with ease.

#1. Are electronic signatures as secure as handwritten signatures for banking?

Yes, electronic signatures are as secure as handwritten ones when properly protected

. Banks regularly assess risk, layer security, monitor, report, log, safeguard emails and browsers, and verify identities to prevent foul play.

#2. Can I use my phone to sign important banking documents?

Yes, you can use your phone to sign important banking documents

. Most banks will let you do so through their app or website.

Do Banks Accept Electronic Signatures? All You Need to Know 

Learn how to optimize PDF for web use to improve load speed, reduce file size, and boost SEO with simple, effective optimization techniques.

When you learn how to optimize your PDF for the web, you can ensure your documents always perform their best online. Unoptimized PDFs are slow to load and hard to navigate, so they can frustrate visitors and increase bounce rates.

This is especially true for mobile users or anyone with a slower Internet connection. Fortunately, there are simple techniques that you can use to compress PDF size, enhance performance, and support your overall search engine optimization (SEO) strategy.

Large PDFs can slow down load times, frustrate users, and negatively impact SEO.

Uncompressed images, embedded fonts, excessive metadata, and complex graphics can increase the size of PDFs.

Compressing images, streamlining fonts, removing unnecessary content, implementing lazy loading, splitting PDFs, and using PDF/A are effective PDF web optimization techniques.

PDF.net can help you compress, split, convert, and clean up PDFs quickly and easily for optimal web viewing.

it directly affects how quickly it loads on a website

. A large PDF can slow down page speed, which frustrates users and increases the likelihood they leave before seeing your content. Statistics show that users expect web pages to 

, and this expectation extends to embedded or linked documents.

slower connections and limited bandwidth, which makes loading large PDFs a hassle

. These files put a strain on the device’s processor, draining battery life in the process. All of this adds up to a poor user experience that can deter visitors from engaging with your content in the future.

The bandwidth costs for businesses serving large PDFs can also be substantial. Businesses that regularly distribute PDF catalogs, reports, or manuals may face higher server costs.

Slow-loading PDFs can interfere with SEO, too

. Google factors page speed into rankings, and large PDFs can reduce overall site performance. Even if a PDF is not embedded, linking to it may still affect bounce rates and time on site, which are important signals for SEO.

Users on limited data plans or older devices may struggle to open or interact with a large file

. If they cannot access the information easily, they are unlikely to stay engaged or return.

Reducing PDF file size helps deliver a faster, smoother experience. 

Optimized PDFs load more quickly, perform better in search results, and provide value across all devices

. It is a small technical fix that makes a big difference in how users interact with your site and how search engines evaluate it.

Several factors contribute to oversized PDF files, many of which are easily overlooked during documentation creation.

One of the biggest causes is high-resolution images. Photos or graphics that have not been compressed

 can increase the file size by up to 90% 

Another common issue is embedded fonts. While embedding ensures that your text displays correctly across devices,

 including full font libraries instead of only the characters used can inflate file size

. Many PDFs include hidden information such as author details, editing histories, and unused layers. These serve no purpose for the reader but still take up space.

Complex vector graphics and detailed design elements, like layered illustrations or interactive forms, can make the file heavier

 as well. They are particularly demanding on older browsers and mobile devices.

combining too many pages or resources into a single file can result in a bloated PDF

. If the document contains hundreds of pages, 

Optimize PDFs for Web: Step-by-Step Guide

A web-optimized PDF should feel seamless to the user while maintaining its readability and functionality. The checklist below covers practical steps you can take to optimize your PDF for web use.

Images are often the largest contributors to PDF file size. Compressing them before or during the creation can make a difference. 

Start by resizing images to match their display dimensions

. There is no need to include a 4000-pixel-wide photo if it will only be shown at half that size on screen.

. A good target is between 100 and 150 dots per inch (DPI). Many desktop publishing tools will let you downsample images directly when exporting to PDF.

If the PDF is already created, you can use our online PDF editor tool to compress the file. Simply upload it, and we will apply automatic image compression and remove excess data to optimize your PDF for web viewing.

Understanding the different image formats within PDFs can also help you make better compression decisions. PNG files are typically larger than JPEGs, so they should be used sparingly in web-optimized PDFs.

convert PNG images to JPEG to reduce your PDF’s size

. Newer formats like JPEG 2000 can provide better compression than standard JPEG while maintaining higher quality, though browser support may vary.

Fonts can quietly add weight to a PDF, especially when the file embeds full font sets. Although embedding ensures the text appears the same across devices, it is often unnecessary to include every character in the font library.

embed only the characters used in the file

. Most PDF export settings offer this option under advanced font settings. This simple adjustment can save kilobytes or even megabytes, depending on the fonts’ complexity.

. These fonts tend to have smaller file footprints and are already optimized for digital viewing. Avoid using multiple typefaces unless needed, as each additional font adds to the file size.

. Some tools retain fonts that were once part of the file but no longer appear as visible text. You can manually identify unused fonts by comparing the font list in your PDF’s properties dialog with your actual content to optimize your PDF for web use.

#3. Remove Unnecessary Elements and Metadata

PDFs often carry extra baggage that users never see. This includes hidden layers, document histories, author details, and embedded scripts. While these might seem harmless, they increase the file size and can even affect how the document behaves on different platforms.

. Strip out author names, creation dates, and version histories. Unless the document requires this information for archiving or legal purposes, it is better to leave it out to improve PDF speed.

delete any unused objects or hidden layers

. These can include background graphics, alternate layouts, or template elements that were never finalized. Cleaning out unused content not only reduces the file size but also minimizes the chances of rendering errors.

 is another effective way to reduce file size. These are often left behind from the editing process and serve no purpose for end users. Comments can be particularly bulky when they contain lengthy text of multiple replies.

Color profiles and ICC profiles are additional sources of unnecessary bulk in PDFs. These define how colors should be displayed and are essential for print production, but they add significant file size without improving the web viewing experience. When exporting or optimizing PDFs for web use, 

choose settings that exclude these profiles

Some PDFs also contain JavaScript or interactive elements that are not needed for web viewing. If the document does not rely on forms or buttons, 

removing these scripts helps make the file lighter and load faster on your website

. It also limits compatibility issues across devices and browsers.

 is a technique often used for web images, but it can also be applied to PDFs when embedded into a webpage. Instead of loading the entire PDF at once, lazy loading defers loading pages until the user scrolls to them. This improves initial load time and conserves bandwidth, especially for longer documents.

, which restructures the PDF internally so browsers can display the first page quickly while the rest loads in the background. For embedded PDFs, 

combine linearization with iframe lazy loading by adding the loading=”lazy” attribute to your iframe tag

Lazy loading helps reduce bounce rates and keeps users engaged by delivering only what is necessary at any given moment. While it does not reduce the actual PDF file size, it improves perceived performance. That difference matters when optimizing PDFs for web user experience and SEO metrics.

Large, content-heavy PDFs can overwhelm users and slow down load times. 

Splitting them into smaller, focused sections can improve usability and performance.

 For example, instead of one 100-page document, break it into multiple PDFs based on topic, chapter, or section.

This approach reduces the individual file sizes and helps users find information faster. A training manual, for instance, can be separated into different modules, each available as its own downloadable file. Visitors can access what they need without downloading an entire package.

Splitting large PDFS can also make content easier to maintain and update

. Instead of replacing the document every time something changes, you can edit only the relevant section and reupload it. This saves you a lot of time and effort if you are managing many large, content-heavy PDFs that need to be reviewed and revised often.

From an SEO perspective, smaller, topic-focused PDFs have an edge over large, comprehensive ones

. Search engines can more easily crawl and index focused content, and each individual web-optimized PDF can target specific keywords relevant to its topic.

This way of optimizing a PDF for SEO allows your content to rank for various search queries, potentially increasing your overall organic visibility. Additionally, users are more likely to link to and share smaller, specific PDFs that directly address their needs, which can improve your link-building efforts and domain authority.

 is a standardized version of the PDF format designed for long-term digital preservation

. What makes it useful for web optimization is its simplified structure. PDF/A files exclude non-essential features like JavaScript, audio, video, and external content links, all of which can slow down loading or cause compatibility issues.

Because PDF/A focuses on consistency and reliability, it tends to produce cleaner, smaller files that are easier to render across devices. 

 is especially helpful for documents that do not require interactive elements. It also ensures your file meets compliance standards in regulated industries.

There are several PDF/A standards, each with different capabilities and restrictions. PDF/A-1, based on PDF 1.4, is the most restrictive version, excluding all interactive elements, embedded files, and multimedia content. It also does not support JPEG 2000. This makes it ideal for simple text and image documents that need maximum compatibility across devices and long-term accessibility.

PDF/A-2, based on PDF 1.7, allows for some additional features, like embedded files and improved compression methods, but can still maintain archival qualities. PDF/A-4f goes further by permitting the embedding of any file format within the PDF, making it useful for documents that need to include source files or related materials.

For web viewing purposes, PDF/A-1 typically produces the smallest, most efficient files, while PDF/A-2 offers a good balance between features and file size optimization. PDF/A-4f is compatible with modern construction, engineering, and geospatial workflows. 

Choose the standard that best fits your specific use case and PDF web optimization needs

If you want to skip the technical steps and still get excellent results,
