# Unlock PDF files.

> Remove PDF passwords locally — nothing ever gets uploaded.

Remove the password from a PDF you own and get a copy that opens freely. Unlike online unlockers, **both the PDF and the password you type stay on your device** — the whole job runs right in your browser, and nothing is ever sent anywhere.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## Your password never leaves this page

Typing a PDF password into a random website is a leap of faith — you hand a stranger’s server both the document and the key to it. Here there is no server in the loop: the PDF is decrypted and rewritten on your own device, and neither the file nor the password is ever transmitted. The unlocked copy downloads straight from your browser’s memory.

## Two kinds of PDF locks

An open password is the real lock: the file is encrypted and nothing can read it without the password, which is why this tool asks for it once. A permissions lock is softer — the PDF opens fine but printing, copying or editing is restricted. Both come off here, and the unlocked copy behaves like any ordinary PDF.

What this tool never does is guess or crack passwords — if you don’t know the open password, the file stays sealed. Going the other direction, [Protect PDF](https://compress-pro.com/protect-pdf) adds a password to documents you are about to send.

## Frequently asked questions

### Is unlocking a PDF legal?

Unlocking PDFs you own or have the right to use — like invoices, bank statements or reports sent to you with a password — is fine. This tool requires the correct password; it does not crack or bypass anything.

### What if I don’t know the password?

Then the PDF can’t be unlocked here. This tool unlocks with the password you provide — it is not a password recovery or cracking service.

### Why does my PDF open fine but refuse printing or editing?

That is a permissions lock — the file is readable, but flags inside it restrict printing, copying or editing. Unlocking rewrites the PDF without those restrictions, so the copy prints and copies normally in every reader.

### Is it private?

Yes. The document never leaves your browser — nothing is uploaded, and the server only delivers this page. That makes it safe for contracts, invoices, medical records — anything you would not email to a stranger. Want proof? Run one file through, switch your connection off, and run another — it still works.
