Frequently Asked Questions

How secure is the password protection?
We use industry-standard AES-256 encryption to protect your PDF files. This is the same level of encryption used by banks and government agencies. The security of your document depends on choosing strong passwords that are difficult to guess.
What's the difference between the two passwords?
The Document Open Password is required to open and view the PDF. The Permissions Password (also called the Owner Password) controls what users can do with the PDF, such as printing, copying text, or making edits. You can set either or both passwords.
Is there a file size limit?
Yes, you can protect PDF files up to 100MB in size. For optimal performance and faster processing, we recommend keeping files under 50MB. If you have a larger file, you might want to compress it first using our PDF compression tool.
