Form entries, sticky notes and markups become part of the page — nothing can be changed or deleted afterward.
Flattened forms print exactly as they look on screen, ending the missing-text mystery on paper forms.
Flattening happens on your device. Filled contracts and applications never touch a server.
Removing interactive layers often shrinks the file and stops compatibility warnings in older readers.
Flatten as many documents as you need at zero cost — no account, no page limits, on any device.
It merges every interactive layer — form fields, annotations, comments, digital markups — into the page content itself. The visible result stays the same, but the parts are baked in permanently.
A filled form with live fields can render differently in every PDF reader, and some print with blank boxes. Flattening fixes the entries into the page so it looks identical everywhere, on screen and paper.
The interactive layers are gone — you can't retype form fields or delete comments anymore. The page content itself is still a normal PDF, so tools like our Split or Rotate PDF work on it as usual.

The tool works in all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari and Opera. We recommend keeping your browser up to date for the best experience.
