Flatten PDF: questions and answers

What does flattening a PDF do?

It burns form fields and annotations into the page, so what you see can no longer be edited or changed, which is useful before sending a filled form.

Is Flatten PDF free?

Yes. Flatten PDF on Folio is free, with no account, no sign-up and no watermark on the result.

Are my files safe?

Your files are processed on Folio's own server only to run the tool, and deleted automatically after 6 hours. There is no account, so they are not linked to you.
