Remove password protection from PDFs you own. Know the password and the encryption is stripped permanently — privately, in your browser, free.

Upload PDF

Quick Answer

Remove password protection from a PDF you can open. If you know the password, type it and the tool strips the encryption permanently — the downloaded file opens without any password in every viewer. Owner-password-only locks (printing/copy restrictions) drop without needing any password at all.

Key Facts

  • Strips encryption permanently — the output needs no password ever again
  • Know the open-password: type it once and it is used locally to decrypt
  • Owner-only locks (print/copy restrictions) remove without a password
  • Cannot crack unknown passwords — AES-256 is mathematically secure
  • Everything runs in your browser via qpdf WebAssembly

Frequently Asked Questions

How do I remove a password from a PDF?

If you know the password: upload the file, type the password, download — the decrypted copy opens anywhere without it. If the file only has printing/copying restrictions (it opens fine but complains when you copy), leave the password empty and those permissions drop automatically.

Can this tool crack a PDF password I do not know?

No. It uses your password to decrypt the file locally — there is no cracking. Anything advertising unknown-password AES-256 removal is either lying or running a decades-long brute-force.

Why does my PDF open without a password but still say locked?

That is an owner password — permission restrictions on printing, copying, or editing. Viewers honor it, but it does not encrypt the content. This tool removes it without needing any password, restoring full printing and copying.

Is unlocking PDFs legal?

For your own documents, yes. Removing protection from files you do not own or are not authorized to modify can violate copyright or contract law. The tool is built for the legitimate case: your files, your password, your choice of viewer.
