Unlock PDFs on Windows — locally, privately, instantly
Remove a known password from a PDF file without uploading it anywhere. PDF LockSmith processes every file on your device using QPDF — your documents never leave your machine.
How unlocking works
Drag a password-protected PDF into PDF LockSmith, enter the password you know, and the app creates an unlocked copy. The original file stays untouched. The result saves automatically next to the original or in your chosen output folder.
There is no cloud step, no account, and no upload. The entire process happens on your Windows desktop.
