Unlock PDF

Remove the open-password from a PDF you already know the password to — useful before merging, compressing or editing a protected file, since most PDF tools can't process an encrypted one directly.

How it works

Private by design

The file never leaves your device — everything runs inside your browser tab using JavaScript PDF libraries, with nothing uploaded to any server. That also means there's no per-day limit on how many files you process, since nothing is metered on a server.

Good to know

A larger PDF is handled a page at a time internally, so it takes a little longer rather than failing outright — closing other heavy browser tabs helps if the device has limited RAM.

Frequently asked questions

Can this remove a password I don't know?

No — you must already know the current password; this only strips it, it doesn't guess or crack it.

Is there a sign-up or a watermark?

No — no account needed and the output file carries no watermark.

Does it work on mobile?

Yes, it runs in any modern mobile browser on Android or iPhone, not just on desktop.

Is my file kept or deleted after processing?

Neither — it's never uploaded in the first place, so there's nothing stored on any server to delete.
