Flattening makes form fields and comments part of the page so they print/share consistently and can't be edited.
Your files are processed locally and never uploaded to a server.
About Flatten PDF
Flattening bakes form fields and comments directly into the page. The PDF still looks the same — but text, signatures and annotations become un-editable and render correctly in any viewer.
