Flatten PDF
Make forms and annotations part of the page for good.
Free, no sign-up. It runs inside your browser: your files never leave your device.
Flatten a PDF so form answers, comments and stamps become part of the page and can no longer be changed. Do this before you send a filled form or a signed document.
How to use Flatten PDF
- Drop one or more PDF files on the page.
- Under How, choose "Keep text and drawings" or "Turn pages into pictures".
- For the first, turn on "Only form fields" to leave comments as they are. For pictures, pick the sharpness and JPEG or PNG.
- Click "Flatten".
Questions
Will the text still be searchable?
With "Keep text and drawings", yes: text stays searchable and sharp. With "Turn pages into pictures", text can no longer be searched or copied.
What does "Turn pages into pictures" remove?
Each page is drawn into a brand-new file, so no metadata, layers, scripts, fonts or hidden text come along.
Can I flatten only the form and keep the comments?
Yes. Turn on "Only form fields".
Is my file sent anywhere?
No. Flattening runs in your browser.
