Frequently asked questions
What does flattening a PDF do?
It converts fillable AcroForm fields into static page content and drops leftover annotation widgets. It does not rasterize drawings that are already part of the page stream.
Why should I flatten a PDF?
Flattening prevents others from altering your filled data and ensures the document displays correctly on all PDF viewers and printers.
Can a flattened PDF be un-flattened?
No. Once flattened, the data becomes part of the page content. Keep an unflattened copy if you need to edit it later.
Is this process secure?
Yes. The flattening process runs entirely on your device, so your data remains private.
