Learn how to encrypt a PDF with different tools to protect sensitive data, preventing unauthorized access and usage of your documents.

To encrypt a PDF and keep your documents secure, you can use an online tool like pdf.net, Preview (Mac), or Microsoft Word.

This is a helpful way to protect your documents from unauthorized use, editing, and sharing. Additionally, encrypting a PDF will keep your sensitive data safe, which can also help you align with data protection policies set in force by the government or other institutions.

If you're new to PDF encryption, this guide covers why it matters, how encryption levels like AES-128 work, and how to encrypt a PDF both online and offline.

PDF document encryption is a safety procedure that helps you secure confidential information and restrict PDF access, usage, editing, and sharing.

Encrypting PDFs can help you protect documents and comply with the most widespread security regulations (HIPAA, GDPR, CCPA, etc.).

pdf.net secures your files with AES-128 encryption, the same standard trusted by banks and healthcare providers.

In addition to encryption, our software allows you to add signatures to your PDFs for extra security, but also modify, highlight, and annotate text based on your needs.

Encrypting a PDF is important because it 

 helps you stay compliant with various security regulations

Let’s learn more about the encryption benefits:

You can encrypt PDFs to keep specific information a secret; this process renders data into unreadable text, which users can only access if they have the correct password.

Encryption is especially important for highly confidential documents, as it can prevent data leaks. For instance, it is recommended when securing medical and business documents containing sensitive data such as 

patient diagnoses, employee salaries, and 

Not protecting your files can lead to the revelation of such information, which can cause serious problems, damage a company’s or person’s reputation, or affect your future professional endeavors and collaborations.

, which is a common threat nowadays, as it allows you to secure personal information such as your ID card number and SSN.

And finally, PDF metadata also poses a risk of identity theft because it can reveal personal information (e.g., data about the PDF author). You can edit PDF metadata or use encryption to make them inaccessible, both of which are 

practical ways to make your personal details safe

#2. Preventing Unauthorized Editing or Sharing

 for your files and prevent unauthorized access. This can also prevent illegal sharing, because even if your file ends up where it should not be, no one can retrieve the data without the decryption password.

For example, if you sell books in the PDF format online, you can encrypt each copy and share the passcode for decrypting it with buyers.

Not having access to encrypted files also makes such PDFs non-editable and prevents any modifications to your files. Some PDFs contain instructions that must stay unchanged. Encryption ensures your files remain intact and functional.

is a top priority for businesses and professionals. Otherwise, business competitors, hackers, and other individuals with malicious intent can copy and use patents, designs, and scientific discoveries without authorization.

This can hurt the creator’s business and revenue. In some cases, misuse of intellectual property may even endanger others.

#3. Compliance with Data Security Regulations

Encrypting your files is the easiest way to comply with strict data security policies that certain countries and companies propose.

Let’s check out some well-known security regulations:

 The California Consumer Privacy Act dates from 2020 and regulates consumer rights, allowing them to know what data is gathered or sold and for what purpose.

. The General Data Protection Regulation, enacted by the European Union in 2018, requires organizations to protect the personal data of EU citizens and residents and gives individuals the right to control how their information is collected, stored, and shared.

. The U.S. Department of Health and Human Services issued this act in 1996 to protect sensitive information in the medical industry. It grants individuals the right to know and decide how their medical data is used.

. The Payment Card Industry Data Security Standards are a non-governmental regulation created by the leading credit card companies. It ensures privacy protection with quarterly vulnerability scans and annual assessments, which help perform transaction audits.

So, if you fail to encrypt your documents, it might lead to unauthorized data exposure and the

How to Encrypt a PDF Using Microsoft Word

Encrypting a PDF using Microsoft Word works well for simple files, but 

 and back can shift formatting in documents with complex layouts, tables, or images.

That said, here’s how to do it step by step:

Open the PDF in Word (Word converts it into an editable document).

PDF Encryption Levels: AES-128 vs. AES-256

PDF protection depends on the encryption standard behind it

, and understanding the difference helps you choose a tool you can actually trust.

, which is now considered breakable with modern computing power. There are three AES encryption types (128, 192, and 256), but the two 

 which encrypts your file using a 128-bit key. It's the encryption level pdf.net uses to protect every file you secure, and it's the same standard trusted by banks, healthcare providers, and government agencies.

 uses a longer, 256-bit key, making it mathematically even harder to break. It's often reserved for highly classified files, though the practical difference in everyday document security is minimal since brute-forcing either standard is already unrealistic.

For most personal, business, and compliance needs, AES-128 encryption offers more than enough security to keep your documents safe.

Owner Password vs. User Password: What's the Difference?

PDF encryption actually relies on two different types of passwords, and knowing the difference explains exactly what your encrypted file will and won't protect.

 (also called an open password) controls whether someone can open the file at all. Without it, the PDF stays completely unreadable, this is the type of password our tool creates for you.

 (also called a permissions password) doesn't block access to the file. Instead, it restricts what a reader can do once it's open, such as printing, copying text, or editing the document.

It's worth knowing that permissions set with an owner password can sometimes be bypassed with third-party software, since the file itself isn't locked. If keeping unauthorized readers out entirely is your priority, a user password is the stronger choice.

5 Tips for Creating a Strong Encryption Password

Even AES-128 encryption is only as strong as the password protecting it. Follow these best practices when setting yours:

 Longer passwords are exponentially harder to crack through brute force.

 Combine uppercase and lowercase letters, numbers, and symbols.

 Skip names, birthdays, or anything easily guessed or found on social media.

Use a different password for each sensitive document.

 Reusing the same password means one leak compromises every file it protects.

 This keeps your password strong and memorable without writing it down somewhere unsecured.

 allows you to modify them further in terms of 

Here are the main features for tweaking PDFs to perfection:

If you know the password for an encrypted PDF, our 

 tool lets you remove that protection in seconds. Simply upload your file, enter the current password, and download a fully accessible, editable copy.

However, keep in mind that pdf.net cannot unlock a PDF if you don't have the password. This applies to any properly encrypted file, including one you protected yourself using AES-128 encryption.

In addition to removing the password itself, you can also remove PDF restrictions once you have access to the file. For instance, if a

 or translate texts from English into numerous languages, including Italian, German, Spanish, and Portuguese, and vice versa.

PDF encryption provides the highest security levels to your documents, which helps you protect your data and prevent unauthorized file use or sharing. Whether you choose an online tool like pdf.net or a built-in option like Microsoft Word or Mac Preview, encrypting your PDF only takes a few minutes and goes a long way toward protecting your data.

As a result, you can avoid data leaks, identity theft, and other repercussions such as a damaged reputation caused by information leakage.

#1. Can I remove encryption from a PDF later?

Yes, you can remove encryption from a PDF 

. Aside from this scenario, it is impossible to reverse this process.

#2. What happens if I forget my password?

, you will not be able to access your PDF. Our unlock tool can only remove a password you already know; it cannot recover or bypass a forgotten one, regardless of the encryption level used.

Yes, PDF encryption is safe from hackers when it's backed by a strong standard like the AES encryption, which would take far longer than a hacker's lifetime to crack through brute force. On the other hand, your PDF encryption may be easy to breach if you use cheap tools for the same purpose.

#4. Can I encrypt a PDF on my mobile device?

Yes, you can encrypt a PDF on your mobile with

pdf.net since it’s fully browser based. No need for software installation or steep learning curves.

How to Encrypt a PDF and Keep Your Documents Secure

Remove password protection from your PDF in seconds

We tested 8 tools head-to-head to find the best PDF password remover online in 2026, timing every unlock and checking use limits.

An online PDF password remover is a browser-based tool that strips a known password from a protected file, so you can open, edit, or share the file without re-entering that password every time. It helps whenever you have the correct password, but retyping it every time you open the file, or sending a locked PDF to someone else, slows you down.

To find the best PDF password remover online, we ran the same password-protected PDF through eight popular tools, including PDFgear, PDF24, iLovePDF, pdf.net, PDF2Go, PDF Candy, Smallpdf, and Sejda, checking what each one lets you do. Here’s what we’ve found.

PDFgear and PDF24 unlocked our test file for free, with no account and no file-size limit we could find.

pdf.net accepts more input formats (including HEIC and Markdown) and lets you keep editing, signing, and re-protecting the file afterward without switching tools.

Speed varied by about a second between tools: iLovePDF, PDFgear, PDF2Go, and PDF Candy unlocked files in 1-2 seconds; pdf.net, Smallpdf, and PDF24 took 2-3 seconds.

Sejda failed to unlock either of our test files, even though it otherwise tested well for editing and form tools elsewhere in our review.

A password remover software only unlocks the file itself; if a PDF also blocks printing or copying, you'll need to remove PDF restrictions separately, which we cover below.

How We Tested These PDF Online Password Removers

We tested these PDF online password removers by uploading the same 

 to all eight tools, entering the correct password, and recording what happened next. For every tool, we tracked:

How long the process took, from upload to a downloadable file

Whether an account was required, and what free-use limits applied

The maximum file size allowed on the free tier

Whether the unlocked PDF kept its original formatting and quality

 across every tool and repeated the process where a tool offered more than one unlocking method. All of the tools we tested require you to enter the existing password before they unlock the PDF file.

That's because PDF password protection typically relies on strong ciphers like the

How to Choose the Right PDF Password Remover

Choosing the right PDF password remover implies 

: how large PDFs are, how often you need to unlock them, and whether you're comfortable creating an account or paying upfront.

That said, consider the following before you opt for an online PDF password remover:

 If your PDF is under 50 MB, almost any tool works. Larger files almost always require some kind of subscription.

 For a one-off unlock, a free tool with a low usage cap is fine. If you need a PDF unlocker on a regular basis, unlimited free access saves you from hitting a wall.

 A password remover only handles password-protected files. If your PDF instead blocks printing, copying, or editing without a password, you'll need to 

 separately, since that's a different kind of lock.

Is It Safe to Remove a PDF Password Online?

Removing a PDF password online is safe as long as the tool 

. However, you should still avoid uploading highly sensitive documents to a site you don't recognize.

Therefore, before you trust any online tool to remove a password from a PDF, it's worth spending time on a 

few practical checks before you upload anything

Confirm the page uses HTTPS, which encrypts the file in transit. The U.S. Customs and Border Protection agency's own 

guidance on password-protecting PDF documents

 is a useful reference for how government agencies handle document security on their end.

Check whether the tool states a file-retention policy. Therefore, look for 

 before uploading sensitive files to any third-party service.

Be cautious of unsolicited links claiming to "unlock" a PDF sent to you by email. The FTC's guide to 

 notes that fake attachments and lookalike tools are a common way attackers steal credentials.

, removing the password only for that one exchange, rather than permanently, keeps the file protected everywhere else it's stored.

Our testing found that the free tools, like PDFgear and PDF24, handled password removal just as well as the paid options, while Sejda's failure was the biggest surprise in the roundup. If you only need to unlock a PDF you already have the password for, start there before paying for anything.

For everything else you might need to do with that file afterward, from 

 to editing or converting it, look for a 

#1. Which PDF password remover is completely free?

PDFgear and PDF24 were completely free in our testing, with no account, payment, or file-size limit standing between you and your unlocked file. Both handled our test PDF in under three seconds, making either the best online PDF password remover for everyday, no-cost use.

#2. Can I unlock a PDF without a password?

You can only unlock a PDF without a password if a tool offers a dedicated "unknown password" feature, and even then it's not guaranteed. PDF Candy offers this option, but it failed on both of our test files, so most password-protected PDFs still need the correct password before any of these tools will touch them.

#3. Is it safe to use an online tool to remove a password from a PDF?

Using an online tool to remove a password from a PDF is safe if the site uses HTTPS and deletes files after processing. Avoid uploading highly sensitive documents, like financial or legal records, to any tool you haven't verified first.

#4. How do I open a locked PDF if I forgot my password?

 for by recovering the original password first, not by using a password remover; none of the eight tools we tested can guess or crack one. Check a password manager or old emails for the original, or contact whoever created the file.

#5. What if my password-protected file is a word document, not a PDF?

A PDF password remover won't work on a Word file, since the two formats protect content differently. If you're locked out of a .docx instead, check our guide on 

#6. Can I remove a password from a PDF without Acrobat?

Yes, all of the eight tools we tested act as 

 for unlocking files online since Adobe doesn't support unlocking/removing passwords on the web app . PDFgear, PDF24, iLovePDF, pdf.net, PDF2Go, PDF Candy, and Smallpdf all removed our test PDF's password entirely in the browser.

Yes, once a password remover strips the protection, the unlocked PDF stays that way permanently; none of the tools we tested re-lock the file or expire the change.

Bank statements are safe to share if sent securely to trusted recipients. Learn risks, redaction tips, and how to protect your financial data.

Bank statements can be safe to share, but only when they are sent securely to trusted recipients for legitimate purposes, such as loans, rentals, tax filing, or identity verification. Since they contain sensitive financial and personal information, sharing them carelessly increases the risk of identity theft, fraud, phishing scams, and privacy breaches.

That said, this article explains when it is safe to share a bank statement, the biggest risks to watch for, how to protect financial PDFs before sending them, and the best practices for securely handling sensitive banking documents online.

It can be safe to share a bank statement when the request is legitimate, the recipient is trusted, and sensitive information is properly protected.

Sharing bank statements can expose you to risks such as identity theft, financial fraud, phishing attacks, and loss of privacy if the document falls into the wrong hands.

To safely share a bank statement, redact unnecessary details, use secure PDFs, password-protect files, and send documents through trusted encrypted sharing methods.

Following financial document security best practices such as verifying recipients, avoiding unsecured platforms, securely storing files, and limiting unnecessary sharing can help reduce the risk of data exposure.

Is It Ever Safe to Share a Bank Statement?

Yes, it is safe to share a bank statement, but 

Lenders, landlords, accountants, and government agencies often request them as proof of income, proof of address, or financial verification, in situations like:
