PDF Unlocker

Remove password protection from PDFs you have permission to unlock.

Preparing the editor...

The guide and instructions on this page are available while the tool loads.

PDF Unlocker helps remove password protection from PDFs when you already know the correct password.

It is useful for your own documents when you need an unlocked copy for editing, printing, merging, or archiving.

This browser-based approach relies on QPDF compiled to WebAssembly rather than pdf-lib, because QPDF supports decrypting PDFs with the correct password.
