Good to know

When to use the Unlock PDF
- Remove the password from your own statement so it prints easily.
- Make archived documents easier to open later.

Troubleshooting
The file does not open
Check that it is one of the supported formats above and opens in another app. Damaged files and password-protected PDFs cannot be read until they are repaired or unlocked.
It is slow or stops on a very large file
Everything runs on your device, so speed depends on its memory. Close other tabs, use a computer rather than a phone, or split the file into smaller parts first.
The download did not start
Look for your browser’s download bar or icon. Some browsers ask once before a site may download files; allow it and click the button again.

Can it crack a password I do not know?
No. You need the password. This tool only removes protection from files you are allowed to open.
Are my files uploaded?
No. Your files are processed on your own device by your browser. They never leave your computer or phone, and there is no file size limit other than your device’s memory.
