Are my files safe?

Yes. Your files are only used to create your result — they’re never shared and never used to train AI.

My PDF shows no fields — why?

Some forms are just printed lines with no real form fields. You can still add text and a signature with Sign PDF.

Will the answers look right in every viewer?

The answers are written into the form fields. Turn on Lock answers to flatten them into the page so they look the same everywhere and can't be changed.
