About this tool
Keep a document private before you send it. Set a password, and nobody can open the file without it. You also decide whether readers can print it, copy from it, or change it.
Common questions
How strong is the protection?
Files are encrypted with AES-256, the current standard for PDFs. A long password is what keeps them safe.
What if I forget the password?
It can't be recovered, so keep it somewhere safe.
Is it free to use?
Yes. You can use it without an account a few times a day, and a free account raises the daily limit. Nothing is added to your file unless you ask for it.
What happens to my files?
Your files are only used to run the tool you chose, and they're deleted automatically after about 24 hours.
Do I need to install anything?
No. It all works in your browser, on any computer or phone.
