After annotating a PDF (highlights, comments, freehand drawings), flatten the annotations so they become part of the page content - permanent, unremovable, embedded. Useful when distributing reviewed PDFs where you don't want recipients to easily remove your annotations.
When to use this
Use to: distribute reviewed contracts with annotations baked in, lock highlight markup on study notes for resale, prevent annotation removal on signed-off documents, archive PDFs in their annotated state.
Frequently Asked Questions
Can the recipient still see who made the annotations?
No - flattening removes the annotation metadata (author, timestamp, comment threads). The visual content stays, but it's now just part of the page, not a separately-attributed annotation.
