Frequently asked questions
What does flattening a PDF do?
Annotations, highlights, and form fields stop being interactive objects and become permanent parts of the page — like printing and rescanning, but lossless.
When should I flatten?
Before sharing a filled form or annotated document when you want the content fixed in place — nothing can be edited, moved, or accidentally hidden by another viewer.
