Comment
Leave notes on a document by dropping a pin on the page and typing your note. When you save, the notes become real PDF annotations — the kind a reviewer sees in any PDF program — not marks baked into the page.
How to do it
- Choose Comment, from the toolbar or the Comment group in the Tools panel.
- Click the spot on the page where you want the note. A little box opens.
- Type your note and click Save Note (or press Enter; use Shift+Enter for a new line, Esc to cancel).
- To change or remove a note later, click its pin.
What to know
- Comments are real annotations. They stay as notes attached to the document, which anyone can open, reply to, or clear in their own PDF program — they aren't flattened into the page.
- They're pending until you save. A note you've dropped is held in the app and written into the document when you Save.
- Reorganizing pages clears unsaved notes. If you rotate, delete, or reorder pages while you have unsaved comments, those pending notes are cleared — so save your comments first.
