Key Features

  • Remove PDF passwords

    Decrypt password-protected PDFs when you know the user or owner password.

  • Modern encryption support

    Handles AES-256 and legacy RC4 encryption used by common PDF tools.

  • Private & local

    Decryption runs in your browser - files and passwords never leave your device.

How to Use

  1. 1

    Upload a PDF

    Drop a password-protected PDF or browse to select the encrypted file.

  2. 2

    Enter the password

    Type the user or owner password. Some PDFs open with an empty user password.

  3. 3

    Download the unlocked PDF

    Run unlock, then download the unencrypted copy with a new filename.

Use Cases

  • Reopening an old encrypted archive

    Remove password protection from an older document you still have the passphrase for so it opens without re-entering it each time.

  • Preparing a file for merging or splitting

    Unlock a protected PDF first so it can be combined, split, or rotated with other ToolMint PDF tools.

  • Removing restrictions for internal editing

    Decrypt a PDF that restricts copying or printing when you are authorized to edit or reuse its content internally.

  • Simplifying distribution after sign-off

    Remove a password from a finalized document once approval is complete so recipients no longer need the passphrase.

Examples

Open an archived contract

Remove the password from an old encrypted contract you still have the passphrase for.

contract-2020.pdf + password
contract-2020-unlocked.pdf

Prepare a file for merging

Unlock a protected PDF so it can be merged or split in other ToolMint PDF tools.

protected-report.pdf + owner password
protected-report-unlocked.pdf

Benefits

  • No upload or account required
  • Supports common AES-256 and RC4 encryption
  • Shows encryption status before you unlock
  • Clear errors for wrong passwords or unsupported files

Best Practices

  • Confirm you are authorized to remove protection from the document.
  • Try the owner password if the user password fails, or vice versa.
  • Keep the original encrypted file until you verify the unlocked copy opens correctly.

Common Mistakes

  • Expecting the tool to recover a forgotten password - it cannot.
  • Uploading a PDF that is not encrypted and expecting a change.
  • Using special characters in passwords without checking keyboard layout or caps lock.

Privacy Notice

All decryption runs in your browser. PDF files and passwords are never uploaded to ToolMint servers.
