Frequently asked questions
What exactly is flattened?
All interactive form fields (text boxes, checkboxes, dropdowns, signatures) and annotations are merged into the page content. The visual result is identical.
Can I un-flatten a PDF after?
No — flattening is permanent. Keep a copy of the original if you may need to edit the form again.
