Frequently asked questions
How strong is the protection?
The PDF is encrypted with the password you set. Choose a long, random password — never reuse one.
What if I forget the password?
There is no way to recover it, so store it somewhere safe.
Are my files uploaded to a server?
No. Bynd PDF runs entirely in your browser, so your files are processed on your own device and never sent to us or anyone else.
