Your password never leaves this browser tab — everything runs locally.
Private by design. Remove password protection from a PDF you have the password for, so it opens freely. Your file is processed entirely in this browser tab using WebAssembly — it is never uploaded anywhere, so it stays yours even on a shared or offline computer.
Frequently asked questions
- Do I need to know the password?
- Yes. This tool removes password protection from a PDF you already have the password for — it cannot recover or guess a forgotten password.
- Is the password sent to a server?
- No. The password and your file stay in this browser tab — decryption runs locally, and nothing is ever uploaded.
- Why did it say the password did not work?
- Double-check for typos or extra spaces. If it still fails, the PDF may use an encryption method this tool does not support yet.
