When this tool helps
- Make filled-in form fields part of the page, so the answers can no longer be changed in a PDF reader.
- Remove comments, highlights and other annotations before sending the final version.
- Prepare a filled-in form for printing or archiving.
Good to know
- Links in the document are removed too, because they are annotations. Text stays text — the page is not turned into an image.
- If the file has no form fields or annotations, you get an identical file and a message that there was nothing to flatten.
