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.
Use the tool with a privacy-aware browser-based workflow.
Use only on PDFs you own or are authorized to unlock.
