Password Protect and Unlock PDFs Offline

🔒 Strong Local Encryption

Encrypt your files with standard owner and user passwords. Specify custom permissions for printing, editing, and copying content safely.

🔓 Instant Password Removal

Provide the password of a secured PDF to decrypt it permanently. Save a copy of the unlocked PDF without password restrictions in milliseconds.

Frequently Asked Questions — PDF Security

Can you recover my PDF password if I forget it?

No. Because Amendly runs strictly client-side and never transmits your files or passwords to our servers, we have no access to your credentials or files. Make sure to keep your passwords saved securely.

What encryption standards are supported?

We leverage PDF-Lib's native encryption handlers to apply standard document restrictions that are compatible with any compliant PDF reader, including Adobe Acrobat, Chrome, and iOS/Android systems.

Can I decrypt any PDF without a password?

No, our unlocking utility requires you to enter the correct original document password. This ensures files are only decrypted by users who have authorized access to their contents.
