Why Flatten PDF?
Filled out a PDF form and need to submit it? Some systems reject PDFs with editable form fields. Flattening "bakes in" the content, converting form fields to regular PDF content.
This also merges layers and annotations. The result is a simpler PDF that displays consistently everywhere and can't be accidentally edited.
Common use: government form submissions, legal documents, and any time you need the content to be permanent.
