PDF ToolsHow to use Annotate PDF
- Choose your PDF to enter Review mode in the shared document workspace.
- Choose Highlight and select document text, or drag an area. The markup style menu also offers Underline and Strikethrough.
- Choose Comment to place a sticky note, or use Draw a box, Arrow or Draw. Select a mark and enter its comment in Properties.
- For markup added here, add replies and use Mark resolved in Properties. Choose another mark from the Comments list when no item is selected.
- To revise markup from another reader, choose Edit existing comments and select its outline. Update the message, color or resolved state. Use Add reply to changes for a new reply, then Apply comment changes.
- Choose Save and download to keep native PDF annotations and editable review threads. Keep the flatten option off to preserve comment threads.
Before you export
Remove existing comment removes the selected annotation and its discussion. Undo restores them. Editing an existing comment keeps its native PDF coordinates and preserves unrelated annotations. An unchanged appearance stays intact; supported color changes rebuild the appearance for that annotation.
Unsupported annotations remain in the PDF and explain why they cannot be edited. Existing-comment editing is unavailable on digitally signed documents. Annotation and review-state display varies between PDF readers. Flatten added markup and form fields applies to markup created here and form fields; it does not flatten imported annotations.
The document stays in memory for this browser session. Export a copy before closing or reloading the tab. Undo history is not saved in the PDF; added objects are saved for reopening unless flattened.
