Note: you can easily view and edit all the comments you have added to a document by opening the Panel and selecting the Notes section.


  • Click inside a comment in the Panel to add a reply note to the comment.
  • Click inside a note in the Panel, then click the three dots that appear on the right to Edit or Delete it. (Deleting it in the panel will also delete it from the document.)

    Tip:  When several people comment on a file, the responses are saved in a sequence below the first comment. (The flow of responses and comments in Lumin PDF is the same as you see in Google Docs.)

    Tip: You can select the Comment tool with the keyboard shortcut
