FAQ

Questions people ask before trusting a tool

What is the difference between a user password and an owner password?

A user password (open password) restricts who can open and view the PDF. An owner password restricts document permissions such as high-resolution printing, copy-pasting content, and page editing.

How strong is the encryption used?

We use the standard secure client-side encryption algorithms supported by the pdf-lib binary engines, conforming to standard PDF protection specs.

Can someone bypass this password protection easily?

No. Fileora creates proper industry-standard PDF password layers. Any standard compliant PDF reader (like Adobe Acrobat, Apple Preview, Google Chrome) will strictly enforce the password and editing permissions.

Is my password or file ever sent to a server?

Absolutely not. The encryption process occurs completely inside your local browser memory space using JavaScript. Your passwords and PDF file nodes never touch the network.
