Choose a locked PDF, type the password you already know for it, and download an unlocked copy. Decryption uses the open-source QPDF engine in your browser — your file and password never leave this tab. This is not a password cracker: a wrong password simply fails.
Remove the password from a PDF you own: enter the password once and save a copy that opens anywhere — decrypted locally by the open-source QPDF engine.

Remove the password from a PDF you own and know the password for: enter it once, and download an unlocked copy that opens anywhere. Powered by the open-source QPDF engine, running entirely in your browser — the password you type never leaves your device.
Your bank sends every statement as a password-protected PDF — secure for email, maddening for your records. Each quarter you unlock your own statements with the password the bank gave you and file the plain copies in your accounting folder, where your bookkeeping software can finally read and archive them.
Decryption is done by QPDF — the open-source PDF toolkit — compiled to WebAssembly in your browser. Given the correct password, it removes the encryption layer and writes a standard, unprotected PDF with identical pages and content. A wrong password is rejected by the engine itself with an “invalid password” result, and the tool explains that plainly instead of producing a broken file.
No. The tool needs the correct current password and removes it from your copy; it does not crack or guess passwords. Forgotten-password recovery has to go through whoever issued the document.
Removing protection from your own documents, or ones you are authorised to handle, is a normal everyday task — bank statements, your own contracts, your company’s files. Unlocking someone else’s protected document without permission is a different matter; only use it on files you have the right to open.
No. Pages, text, images and layout come through unchanged; only the encryption wrapper is removed. File size can differ slightly because the file is rewritten cleanly.
The password typed does not match the one the file was protected with. Check for typos, extra spaces, and keyboard layout or Caps Lock issues. Passwords are case-sensitive. If a copied password fails, type it manually once to rule out hidden characters.
Neither, ever. QPDF runs as WebAssembly in your browser; unlocking happens in the tab’s memory and closing the tab wipes everything.
