Many apps save a PDF by adding changes to the end, so the old text stays readable inside. Cleaning writes the file afresh, keeping only what the pages show.
Text, images, links and form fields are untouched, and the file still opens everywhere. Only the hidden extras you pick come out.
Checking and cleaning happen in this tab, so the private details you’re removing never leave your device on the way.
