PDF password unlock — remove protection from any PDF
Remove encryption from a PDF using qpdf (WASM) running inside your browser. Owner-only restricted PDFs unlock with an empty password; user-password-protected PDFs need the correct password. Text and layout are preserved. Runs entirely in your browser.
How to use
Drop an encrypted PDF and enter the password if needed (leave it empty for owner-only restricted PDFs). Click Unlock and qpdf (WASM) generates a new PDF without the encryption. Compare side-by-side and download. Batch processing of multiple files is supported.
FAQ
- Is the PDF uploaded?
- No. qpdf runs as WebAssembly inside your browser, so neither the PDF nor the password leave your device.
- Can I unlock a PDF whose password I don't know?
- Not for user-password-protected PDFs — you need the correct password. Owner-only restricted PDFs (where the password just limits actions like printing) unlock with no password.
- Does content stay intact?
- Yes. Only the encryption layer is removed; text, layout and images are preserved exactly.
- How does this run fully in-browser?
- qpdf is compiled to WebAssembly via Emscripten, so no server is involved.
