Can I edit existing text in a PDF?

This is an annotation/overlay editor — you can add new text on top of the PDF. Modifying existing PDF text streams is not supported (it requires re-parsing complex PDF content streams).

What annotation tools are available?

Text boxes, image overlays, emoji, shapes (rectangle, circle, line, arrow), freehand drawing, highlights, whiteout, and stamps (APPROVED, DRAFT, CONFIDENTIAL, etc.).

What is the difference between Flatten and Keep as Annotations?

Flatten permanently composites annotations into the page — they cannot be edited later. Keep as Annotations saves them as PDF annotation objects, viewable and editable in Adobe Reader.

Yes — Ctrl+Z / Ctrl+Shift+Z with up to 50 action history.
