Frequently Asked Questions about Protecting PDFs
Where is my PDF processed and is it safe?
To apply professional-grade cryptographic standards, your PDF is securely uploaded over HTTPS, processed in an isolated sandbox, and temporary processing files are automatically deleted from our servers once the process is complete.
What is the difference between a user password and an owner password?
A user password is required to open and read the PDF. An owner password (or permissions password) restricts editing, content extraction, or high-resolution printing of the document.
