How to Remove a Password from a PDF (If You Know the Password)

7 min read

Learn how to remove password protection from a PDF you own. 4 free methods to unlock and save an unprotected copy on any device.

Tired of typing a password every time you open a PDF you own? If you have the password, you can remove it and save an unlocked copy in just a few steps.

This guide covers four free methods to remove password protection from your PDFs on Windows, Mac, and the web. Each method works slightly differently, so pick the one that fits your setup.

Important: You Need the Password First

This guide is about removing password protection from PDFs you own or have legitimate access to. Every method below requires you to enter the existing password first.

This is not a guide for cracking or bypassing passwords on documents that belong to someone else. If you have lost the password to your own document and have no way to recover it, these methods will not help.

If you know the password and simply want to stop being prompted for it every time you open the file, read on.

Types of PDF Passwords

PDFs can have two different kinds of password protection. Understanding the difference helps you choose the right removal method.

Open Password (User Password)

This password is required to open and view the PDF at all. Without it, the document is completely inaccessible. When you open a password-protected PDF and see a prompt asking for credentials before anything loads, that is an open password.

Permissions Password (Owner Password)

This password restricts specific actions like printing, copying text, or editing the document. You can still view the PDF without entering this password, but certain features are locked. For example, you might be able to read a document but not print it.

Most people looking to unlock a PDF are dealing with an open password. The methods below handle both types.

Method 1: Google Chrome (Free, Any OS)

Chrome has a built-in PDF viewer that makes this the easiest method for most people. No extra software needed.

Steps:

  1. Open Google Chrome on your computer
  2. Drag and drop your password-protected PDF into a Chrome tab (or press Ctrl+O / Cmd+O and select the file)
  3. Enter the password when prompted
  4. Once the PDF is displayed, press Ctrl+P (Windows) or Cmd+P (Mac) to open the print dialog
  5. Change the destination to "Save as PDF"
  6. Click "Save" and choose where to save the file

The saved copy is a brand new PDF without any password protection. You can open it freely from now on.

Best For:

  • Quick one-off unlocking
  • Users who do not want to install any software
  • Works on Windows, Mac, Linux, and ChromeOS

Limitations:

  • Very large PDFs may lose some formatting
  • Interactive form fields may not carry over
  • Bookmarks and internal links may be lost

Method 2: Adobe Acrobat (Windows and Mac)

If you have Adobe Acrobat (the paid version, not just Acrobat Reader), you can remove passwords directly from the security settings.

Steps:

  1. Open the PDF in Adobe Acrobat
  2. Enter the password when prompted
  3. Go to File > Properties (or press Ctrl+D / Cmd+D)
  4. Click the Security tab
  5. In the "Security Method" dropdown, select No Security
  6. Enter the permissions password if prompted
  7. Click OK and save the file

The PDF is now permanently unlocked. This method preserves all formatting, bookmarks, form fields, and other document features.

Best For:

  • Preserving exact document formatting
  • Removing permissions passwords specifically
  • Professional and business use

Limitations:

  • Requires a paid Adobe Acrobat license
  • Acrobat Reader (the free version) cannot remove passwords

Method 3: macOS Preview (Free, Mac Only)

Mac users have a built-in option that requires no extra downloads. The Preview app that comes with every Mac can handle this.

Steps:

  1. Open the password-protected PDF in Preview (right-click the file, choose Open With > Preview)
  2. Enter the password when prompted
  3. Go to File > Export as PDF (not "Save" or "Export")
  4. Choose a file name and location
  5. Click Save

The exported PDF is a new copy without password protection. The original file remains unchanged and still protected.

Best For:

  • Mac users who want a fast built-in solution
  • Maintaining good document quality
  • No internet connection required

Limitations:

  • Only available on macOS
  • Some complex PDFs may have minor formatting changes

Method 4: Online Tools

Several web-based tools can remove PDF passwords without installing anything. Popular options include Smallpdf and iLovePDF.

General Steps:

  1. Go to the tool's PDF unlock page
  2. Upload your password-protected PDF
  3. Enter the password when prompted
  4. Download the unlocked PDF

Privacy Considerations

Before uploading any PDF to an online service, consider what the document contains. These tools process your file on their servers, which means:

  • Your document is temporarily stored on a third-party server
  • Sensitive content (financial records, legal documents, personal information) could potentially be exposed
  • Most reputable services delete files after processing, but you are trusting their policies

For sensitive documents, use one of the offline methods above instead. The Chrome and Preview methods never send your file anywhere.

Best For:

  • Users without access to Chrome or Acrobat
  • Simple PDFs without sensitive content
  • Mobile devices where desktop methods are not available

When to Keep Password Protection

Not every PDF should have its password removed. Consider keeping the protection in place for:

  • Financial documents like tax returns, bank statements, and investment records
  • Legal files including contracts, agreements, and court documents
  • Medical records and other personal health information
  • Confidential business documents like employee records or trade secrets
  • Documents shared with others where you want to control access

If multiple people access a document and the password serves as an access control mechanism, removing it could expose the content to unauthorized viewers. Only remove passwords from PDFs where you are the sole user or where open access is appropriate.

How to Add Password Protection Back

If you have removed a password and want to re-protect a PDF later, or if you need to add password protection to a new document, you can do so with most PDF editors. Check out our guide on password protecting PDFs for step-by-step instructions.

You can also host your PDF online with Linkyhost and use link-level access controls instead of document-level passwords. This lets you share the file with specific people without requiring them to remember a password.

FAQ

Can I remove a PDF password without knowing the password?

No. All legitimate methods for removing PDF passwords require you to enter the existing password first. If you have lost the password to your own document, contact the person or organization that originally created the file to recover it.

Is it legal to remove a password from a PDF?

Removing a password from a PDF you own or have authorization to access is perfectly legal. The password removal methods in this guide simply save a new copy of content you already have the right to view. Do not use these methods on documents you are not authorized to access.

Will removing the password change the PDF content?

The content itself stays the same. However, some methods (particularly the Chrome print method) may cause minor formatting differences. If preserving exact formatting is important, use Adobe Acrobat or macOS Preview.

Do online PDF unlock tools store my files?

Policies vary by service. Most reputable tools like Smallpdf and iLovePDF state they delete uploaded files within a few hours. However, for sensitive documents, it is always safer to use an offline method like Chrome, Adobe Acrobat, or macOS Preview.
