Original qualityKeep original text searchable and artwork sharp. Added annotations are flattened onto the page. Flattened · high qualityReplace each page with an image, including masks. Removes underlying text, links, forms and metadata. Flattened · compactSmaller images for sharing. Text is no longer searchable.

Visual masks are only permanent in flattened exports. Password protection uses the inherited compatibility encryption and is available only for flattened PDFs.
