how to make an electronic signature

You can make an electronic signature by writing it manually and scanning it, creating a copy with Word, or using various online tools. Having an electronic signature can be necessary, especially in today’s digital world, where signing documents digitally is common.

Aside from necessity, there are other advantages to knowing how to make an electronic signature, such as convenience and efficiency. So, in today’s article, we’ll explain the four methods you can use for creating electronic signatures and answer some common questions you may have.

Let’s get started!

Key Takeaways

  • An electronic signature is a digital representation of a handwritten signature, used to sign PDFs, contracts, and other documents online.
  • Electronic signatures differ from digital signatures, as digital signatures are encrypted and offer authentication, while electronic signatures are generally a copy of a physical signature.
  • You can create an electronic signature using Word, scanning a handwritten signature, online tools like pdf.net, or graphic editors such as Canva or Paint.
  • Electronic signatures can be legally binding under the ESIGN Act if proper protocols are followed, such as intent, consent, attribution, and record retention.
  • Benefits of electronic signatures include efficiency, convenience, multi-device compatibility, and enhanced document security.

What is an Electronic Signature?

An electronic signature, or e-signature, is a copy of your handwritten signature. Like your physical signature, it can be used to sign PDFs digitally, including contracts, agreements, and other documents.

That said, the appearance of electronic signatures can vary depending on the method you use to create them. For instance, signing a piece of paper and scanning it will likely create the most accurate copy of your signature compared with an online tool.

Electronic vs. Digital Signature

While the terms electronic and digital are often used interchangeably to refer to an online signature, there is actually a distinct difference between electronic and digital signatures.

Electronic signatures are essentially a copy of your physical signature and can be in the form of an image or a scan. Because of this, it can sometimes be difficult to authenticate e-signatures since anyone can upload someone else’s signature.

However, electronic signatures are also very easy to add; practically any text and PDF editor gives you the option to include your signature. That makes it convenient to use, despite the potential security risks.

Digital signatures, on the other hand, are encrypted with a private key, ensuring their authenticity. When they are applied, only the signer and the receiver can view the document, and it loses its validity if any changes are recorded after signing.

As a result, digital signatures are considered highly secure and reliable, but they require specialized software to apply.

Now, let’s discuss the step-by-step process for each one:

#1. Create it Using Word

Making an electronic signature using Word is one of the most convenient methods on this list since you can also use the tool to sign the document directly.

Here’s how to make an electronic signature in the browser version of Word:

  • First, you need to run the program and click on the Insert tab.
Run Word and click on the Insert tab
  • Then, select Drawing and click on Draw.
Select the Drawing option on the Word menu
Click on Draw
  • Next, choose the pen tool you want to use and start creating your signature. This step may be easier using a drawing pad, but if you don’t have one, a mouse would work as well.
Choose the pen tool you want to use to create your signature
  • When done, click Save and Close. This will save your electronic signature as an image and allow you to make size adjustments.
Save your electronic signature as an image
  • After making an electronic signature, you can open your file in Word and attach your signature to the document.

#2. Write it and Scan it
Write your signature and scan it

If you want to create an e-signature for free, you can simply write on or sign a piece of paper and scan it using your phone. This method for making an electronic signature also yields a near-perfect copy of your physical signature since you are scanning it directly.

However, this method is not as secure as the others on this list because if the scanned image gets leaked, then anyone can use your signature to sign documents. Scanned signatures are also not ideal when signing PDFs since these are in an image format and not a digital signature format.

#3. Use an Online PDF Signature Tool

The best way to make an electronic signature online is to use a dedicated e-signature maker like pdf.net. As an online PDF e-signature tool, pdf.net allows you to create e-signatures and sign documents digitally without downloading any additional software.

All you have to do is upload your file on our tool and select one of these three options:

  • Type. With this method, you can type out your name or initials and choose a signature style from the options provided.

Using pdf.net is a guaranteed way to create secure PDF signatures since our tool is protected by the latest HTTPS encryption, so you won’t have to worry about any data breaches.

#4. Use a Graphic Editor

Aside from a PDF signature tool, you can also use a graphic editor like Canva or Paint to make an electronic signature.

Here’s how:

  • Open the program and create a new file.
  • Use the drawing tool and select the pen and ink color you prefer. While you can choose any color, since electronic signatures are often used in professional documents, it’s best to select black.
  • Next, start drawing your signature.
  • When you’re satisfied with how it looks, save the file to create an image of your signature.

One of the advantages of using this method is that you can closely replicate your physical signature depending on the tool that you use. However, keep in mind that since you are creating an image of your signature, it’s important to keep it secure to avoid any unauthorized copies.

How to Make an Electronic Signature on Your Phone

If you want to sign your documents instantly, no matter where you are, you should make an electronic signature on your mobile, too. The process is very simple and, in many cases, no different than the methods used on a desktop.

For instance, pdf.net signing tool and many of the graphic editors mentioned above work on a smartphone just as well as they do on a computer. That makes it easy to create a signature or sign a document directly within seconds.

However, you can also use built-in tools, like the Notes app on iPhone, to open and sign the document. On Android, this can be done in a PDF reader, such as Adobe Acrobat, or whichever other option is available.

Are Electronic Signatures Legally Binding?

Electronic signatures can be legally binding under the Electronic Signatures in Global and National Commerce Act (ESIGN Act). This means that any online file bearing your electronic signature will be treated the same as a document that you physically signed.

However, to be legally binding, the e-signature process must have the following:

  • Intent to sign
  • Consent to sign
  • Signature attribution
  • Signature protection
  • Copy sent to the signer
  • Record retention
  • Opt-out clause

So, if you want to sign a PDF legally with an e-signature, it’s crucial to follow these regulations; otherwise, the document may not hold up in court.

3 Key Benefits of Using Electronic Signatures

Now that you know how to make an electronic signature, you may be wondering what the benefits of signing PDFs digitally are.

Let’s go over each one in detail:

#1. Efficiency

Signing documents with electronic signatures is significantly more efficient than doing so physically, since you won’t have to print them out, mail them to the signer, and then wait for them to be received.

When you use an electronic signature, you can send an email and have the signed document back within minutes. This is especially useful for businesses that often deal with documents that require signatures, like contracts or invoices.

#2. Convenience

With an electronic signature, you can easily sign documents wherever you are, which is highly convenient for remote workers or global teams. Since you don’t need to physically have the document to sign it, you have the flexibility to approve international business transactions and agreements even on the go.

#3. Security

Using an electronic signature to sign documents means that only you and the sender will see the content of the file, which means you can be assured of the security of the transaction. Moreover, electronic signatures are much more difficult to forge and tamper with than physical ones.

Is it Safe to Use Electronic Signatures?

It’s safe to use electronic signatures as long as you use secure e-signature software for business and other private documents. pdf.net, for instance, has the necessary security measures in place to keep your document protected while using our tool.

That said, while electronic signatures are safe, it’s essential to be wary of the documents you sign as well as the program you use to do so. It’s best to avoid suspicious platforms and to verify the source of the document before signing it to ensure that your electronic signature isn’t leaked.

3 Common Issues When Making Electronic Signatures and How to Fix Them

Common issues when making electronic signatures include the following:

  • Blurry signature. If your electronic signature turns out blurry, you could increase image resolution, change the DPI in settings (ideally to 72 or 96), and adjust scaling to 100%. You can also use online tools to refine the edges and sharpen the image.
  • Non-transparent background. When you scan your signature using your phone, the white background you’ve written on will be visible. This problem is pretty easy to fix, though; use a photo editor like Canva to remove the background and keep only the signature. Then, make sure to save the file in PNG format, as it handles transparency much better than JPEG.
  • Issues with adding the signature to the document. Difficulties with adding your signature may arise from many reasons; for instance, your PDF reader may be outdated, or the document may have some restrictions. That’s why it’s important to always check your program version and permissions, as well as to use the correct tools for signing.
