> Unlock PDF online free: remove the password and printing or copying restrictions from a PDF you can open. No watermark, no sign-up, files never stored.

Take the password and the printing, copying and editing limits off a PDF you're allowed to open. Enter the password once and download an unlocked copy — free, with no watermark and no sign-up.

## How do I remove a password from a PDF?

Open the PDF in Mergevanta's Unlock PDF tool, type its password and press Unlock PDF. You get a copy that opens without a password and has no limits on printing, copying or editing. Files that only restrict printing or copying need no password at all. The tool can't crack unknown passwords.

## Frequently asked questions

### Can I unlock a PDF without the password?

Not if the PDF needs a password to open: you have to know it, and Mergevanta doesn't try to crack passwords. PDFs that open freely but block printing, copying or editing can be unlocked without any password.

### Is my password stored?

No. The password is only used to open the file in your browser tab. In the rare case the file goes to the server, the password travels with it encrypted and is discarded when the request ends.

### Where is my PDF unlocked?

In your browser. Only if your browser can't read a file's encryption are files up to 4 MB sent to Mergevanta's server, encrypted end to end, unlocked in memory and never stored.

### Is it legal to unlock a PDF?

Unlock only files you own or have permission to change, such as your own documents or statements you received with their password. Removing protection from someone else's file without permission may break the law or an agreement.

### Which kinds of protection are supported?

Standard PDF password protection: 40-bit and 128-bit RC4, 128-bit AES and 256-bit AES. Encryption tied to a digital certificate can't be removed without that certificate.

### How do I add a password back?

Use [Protect PDF](https://www.mergevanta.com/protect-pdf) to set a new password and choose what people can do with the file.
