What does flattening a PDF do?

Flattening merges all layers (forms, annotations, comments) into a single layer, making them non-editable and part of the page content.

Why should I flatten a PDF?

Flatten PDFs to prevent form fields from being edited, reduce file size, and ensure consistent appearance across viewers.
