Frequently Asked Questions

What does flattening do?

Flattening converts interactive form fields and annotations into static page content that cannot be edited.

Does this preserve bookmarks and form fields?

Form fields are intentionally flattened into static page content — that is the point of flattening. Bookmarks and the document outline are kept.

What PDF versions are supported?

Flattening works on PDF 1.0 through 2.0. Output is bumped to at least 1.5 if the input used non-flattenable transparency groups.
