Frequently Asked Questions
How strong is the password protection?
We use strong AES-256 bit encryption to password-protect your PDF files. This is an industry-standard level of security used to protect sensitive documents.
What happens if I forget my password?
We do not store your password on our servers, so it is not recoverable. Please make sure to save your password in a secure place, as you will not be able to open the locked PDF without it.
Are my files secure during this process?
Yes. All files are transferred over a secure, encrypted connection (TLS) and are permanently deleted from our servers one hour after processing.
