The practical guide
Choose the kind of PDF flattening your workflow actually needs.
Form flattening preserves normal document structure while making field appearances non-editable; full raster flattening turns complete pages into images.
Rasterize complete pages
Full raster mode can bake forms and annotations into a single page image, but it removes original editability and usually removes selectable text.
Select resolution deliberately
Higher raster resolution improves visual clarity and increases file size and memory use. Choose it only when full-page flattening is necessary.

Questions, answered
Frequently asked questions
What is the difference between form and full flattening?
Form flattening affects interactive form controls; full flattening renders the entire page into an image.
Will flattened forms still be editable?
Ordinary form fields are no longer editable after they are flattened.
Does full flattening preserve searchable text?
No. Full raster flattening replaces page objects with an image; use OCR afterward if searchability is required.
Does flattening securely redact content?
No. Use Redact PDF for permanent removal of selected sensitive areas.
