Annotate PDF: what to know

Annotating adds a layer of feedback to a PDF: highlights, drawings, notes and shapes help a reader find what needs attention. It is useful for reviewing a draft without rewriting its original wording.

Use a consistent color for each type of feedback and keep notes beside the passage they explain. Download a copy and reopen it before sharing, especially if the recipient uses a different PDF reader.

Tips for the best result

  • A highlight is not redaction and does not conceal sensitive text.
  • Keep the unannotated original if you need a clean copy later.
