How to Remove Password from PDF — 4 Methods (2026)

Before removing a PDF password, it's important to understand that PDFs have two types of passwords:

1. User Password (Open Password) This password is required to open the PDF file. Without it, the document is completely inaccessible — you can't view any content. The file is encrypted and the password serves as the decryption key.

2. Owner Password (Permissions Password) This password restricts certain actions — printing, copying text, editing, or extracting pages — but allows the document to be opened and viewed without entering a password. This is also called a "restrictions password."

Key distinction: If you can open and read the PDF but can't print or copy text, it has an owner password (permissions restriction). If you can't open the PDF at all, it has a user password.

According to Adobe, approximately 15% of PDFs exchanged in business contexts use some form of password protection. The most common scenario requiring password removal is when you know the password but want to create an unprotected copy for convenience.

The quickest way to remove a PDF password is using AuraPDF's free Unlock PDF tool:

Step 1: Go to AuraPDF Unlock PDF

Step 2: Upload your password-protected PDF file

Step 3: Enter the document password when prompted

Step 4: Click 'Unlock' — AuraPDF removes the password protection

Step 5: Download the unlocked PDF

Why use this method: • Completely free — no signup, no watermarks • Works in any browser — Windows, Mac, Linux, phone • Takes less than 10 seconds • Files are encrypted during transfer (TLS 1.3) and auto-deleted within 30 minutes • No software installation required

Limitation: You must know the correct password. AuraPDF does not crack or bypass passwords — it removes the protection from a file you have authorized access to.

Chrome's built-in PDF viewer can bypass owner password restrictions (permissions-only, not open passwords):

Step 1: Open the password-protected PDF in Google Chrome (drag the file into a Chrome window)

Step 2: If prompted for a password, enter it to open the document

Step 3: Press Ctrl+P (Windows) or Cmd+P (Mac) to open the Print dialog

Step 4: Change the destination to "Save as PDF"

Step 5: Click Save — Chrome creates a new, unprotected PDF

Why this works: Chrome's print-to-PDF function creates a completely new PDF file from the rendered content. The new file doesn't inherit the original's password protection.

Limitations: • Only works if you can open the PDF (doesn't bypass user passwords) • May not preserve bookmarks, form fields, or interactive elements • Text searchability may be affected (Chrome rasterizes some content) • Hyperlinks in the original document may not transfer

For a cleaner result that preserves all PDF features, use AuraPDF's Unlock tool instead.

Adobe Acrobat Pro (paid subscription, $22.99/month) offers native password removal:

Step 1: Open the PDF in Adobe Acrobat Pro

Step 2: Enter the password if prompted

Step 3: Go to File → Properties → Security tab

Step 4: Change Security Method from "Password Security" to "No Security"

Step 5: Enter the owner password when prompted

Step 6: Click OK, then save the file

Advantages of this method: • Preserves all PDF features (bookmarks, forms, layers, JavaScript) • Works offline — no internet required • Handles both user and owner passwords • Professional-grade result

Disadvantages: • Requires an active Adobe Acrobat Pro subscription ($22.99/month) • Must be installed on your computer • Overkill for occasional password removal

For a free alternative that handles most use cases, AuraPDF's Unlock PDF is sufficient.

For technical users, the open-source qpdf tool provides command-line PDF password removal:

Installation: • macOS: `brew install qpdf` • Ubuntu/Debian: `sudo apt install qpdf` • Windows: Download from the qpdf GitHub releases

Remove user password: ``` qpdf --password=YOUR_PASSWORD --decrypt protected.pdf unlocked.pdf ```

Remove owner password (restrictions only): ``` qpdf --decrypt restricted.pdf unlocked.pdf ```

Why use this method: • Open-source and free • Scriptable — remove passwords from hundreds of files in a batch • No internet connection required • Preserves all PDF structure and features • Trusted by developers and system administrators

When this makes sense: If you're processing many password-protected PDFs regularly, scripting qpdf is more efficient than using any GUI tool.

Is it legal to remove PDF passwords?

Removing password protection from PDFs you own or have authorized access to is legal. Common legitimate scenarios include:

• Removing the password from your own documents for convenience
• Unlocking files where the password was shared with you by the document owner
• Removing restrictions from company documents you have permission to modify
• Unlocking archived documents where the original password holder has moved on

When it's not appropriate: • Bypassing protection on documents you don't have permission to access • Removing DRM or copyright protections from published materials • Accessing someone else's confidential documents without authorization

All PDF password removal tools — including AuraPDF — are designed for legitimate document management. They require knowing the correct password and do not crack or brute-force unknown passwords.
