How strong is the protection?
Files are locked with AES-256, the same encryption standard used by banks. Use a long password that is hard to guess.
What if I forget the password?
Nobody can open the file without it, including us, because we never store your password. Keep a copy of the original file.
Is it safe to upload my files?
Files are sent over an encrypted connection, processed on our servers and deleted automatically after 1 hour. You can also delete them right after downloading.
Do I need to sign up?
No. This tool is free to use without an account.
