Questions

What if I forget the password?

Nobody can recover it, including PDF’R’US, so keep it somewhere safe.

How strong is the protection?

It uses AES-256, the strongest encryption in the PDF standard.

Are my files uploaded anywhere?

No. The tool runs inside this page, on your own device. Your files are never sent to PDF’R’US or anyone else, so there is nothing to delete afterwards. Once a tool has loaded, it keeps working with the internet switched off.

Is it really free?

Yes. There is no account, no daily limit and no watermark added to your files.
