Frequently Asked Questions

Is the encryption strong?

The tool applies standard PDF encryption. For maximum security, choose a long, unique password. Your file is never uploaded โ€” encryption happens entirely in your browser.

What if I forget the password?

There is no password recovery option. Store your password in a secure password manager. You can use the Unlock PDF tool only if you know the password.

Will the protected PDF open in Adobe Reader?

Yes โ€” the protected PDF is fully standard and opens in Adobe Acrobat, Preview, Chrome, and all major PDF viewers once the correct password is entered.
