A welcoming PDF workspace
Combine text notes, marker strokes and outlined shapes to explain changes on a PDF. A review annotation leaves the original page in place, so the recipient can compare your feedback with the source. MassPDF does not provide a shared comment thread or simultaneous editing.
Upload a PDF, add text, highlight details, place images, and keep edits moving in one focused workspace.
Open the document and enter Edit mode. Use Box or Oval to outline an area, then add a Text note beside it. For a draft flyer, circle the date and write Confirm with organizer. Keep the note outside the original text so both the question and its context remain readable.
Review facts first, layout second and spelling last. Use Select to reposition your added annotations. Avoid covering a large region with overlapping marks. If a page becomes crowded, remove unnecessary annotations and write a shorter note before exporting.
Save your changes, download and reopen the result. Verify that every note appears on the intended page. Tell the recipient which file is the reviewed copy and keep the unmarked original. Visible annotations are part of the exported page; do not promise recipients editable discussion threads or secure content removal.
