How to Add Comments to PDFs in SharePoint

Muhimbi’s PDF Editor for SharePoint lets you add comments to a PDF directly in SharePoint Online or on-premises. Start by adding your comment to a specific location in your document, and then customize its colors to make it stand out. Comments can also include a user’s name to help you identify who left specific feedback on a document after multiple users have added comments.

Step 1: Opening a PDF File

Open PDFs in SharePoint

Select a PDF from the SharePoint library and right-click on the three dots menu. Then click Edit with PSPDFKit Editor.

Step 2: Adding Comments to PDFs

Add comments to PDF

Open the PDF annotation tool by clicking the Note icon.

Select the exact area in the PDF document where you want to add comments and click to open the note field. Type the comment and close the dialog. The PDF annotation will be saved, and you can drag it to another place within the document.

Step 3: Editing Comments in PDFs

Edit comments in PDF

In the top-left corner of the screen, there is wide range of options to change the look of your annotations. The default color of the note field is yellow, but there are five other colors to choose from. You can also change the look of the icon of the closed annotation, depending on the type of comment added to the PDF document.

To delete annotations in a PDF, click the recycle bin icon in the top-right corner. Click Save to save the changes to your PDF document.
