What does flattening do?

Flattening converts interactive elements (forms, annotations, layers) into static content that cannot be edited. The visual appearance is preserved.

Can I unflatten a PDF?

No. Flattening is irreversible. Always keep a copy of your original document before flattening.

Why would I want to flatten a PDF?

Flattening ensures the document looks the same everywhere, prevents form editing, and can reduce file size. It's useful for final distribution.
