In short
This tool removes the protection from a PDF whose password you know, so you no longer have to type it each time you open the file: a bank statement, an invoice or an official document received encrypted. Enter the password once, and the tool saves a copy with no encryption or restrictions. A PDF that opens freely but blocks printing, copying or editing can also be freed, without a password; only do so if you have the right to use the document freely. The content is not changed. The tool does not recover an unknown password, and it handles one file at a time. The decryption happens in your browser.
