About PDF Password Remover
What it does
PDF Password Remover takes a PDF you can already open and gives you back an unlocked copy: the open (user) password is removed, and any owner / permission restrictions — no-print, no-copy, no-edit — are stripped along with it. The result is a normal PDF that opens with no prompt and has no usage locks.
How it works
- It runs
qpdf— the real, battle-tested C++ PDF toolkit — compiled to WebAssembly, right inside your browser tab. - When a protected file needs a password, you type it once; qpdf decrypts the document and re-writes it without encryption (
qpdf --decrypt). - The decryption is lossless: text stays selectable and searchable, fonts and vectors are preserved. Pages are not rasterised to images, so file size and quality are unchanged.
What it can't do
- It does not crack passwords. You must be able to open the PDF yourself. If you don't know the password, this tool can't recover it — by design.
- Files over 50 MB aren't supported (they strain the in-browser wasm heap).
- It removes protection — it doesn't add it. Use a dedicated tool if you need to set a password.
Privacy & responsible use
Browser-only, like every ChoreCrush tool. Your PDF and the password you type stay in memory on your device — there's no upload, no server, nothing logged. Only unlock documents you own or are authorised to unlock. Because qpdf re-writes the file, a digitally signed PDF may lose its signature, so verify important documents after unlocking.
