Frequently Asked Questions
What does flattening do exactly?
Flattening merges all interactive elements (forms, annotations, layers) into the base content, making them non-editable.
Will form data be preserved?
Yes, filled form values become part of the static page content. They are visible but no longer editable.
Why would I flatten a PDF?
To prevent further editing, ensure consistent display across viewers, reduce file size, and prepare for printing or archiving.
