What Does Flattening a PDF Mean?

A PDF form contains interactive elements — text fields, checkboxes, dropdown menus, signatures — that recipients can fill in and modify. Flattening a PDF converts these interactive elements into static content that cannot be changed. The visible values are preserved, but the interactivity is removed.

This is useful when you have a completed form and want to share or archive it in a way that prevents further editing, while ensuring it prints and displays consistently across all PDF viewers.
