How to Highlight Text in PDFs in SharePoint

Muhimbi’s PDF Editor for SharePoint lets you annotate text in a PDF directly in SharePoint Online or on-premises. Select a line of text in your PDF to highlight, underline, strike through, or add a squiggle line. Make text annotations stand out by customizing their color and opacity. Include user information with each annotation to help identify the different users that added text highlights to your document.

Add the following text annotations to documents in SharePoint:

  • Highlight text or other content in PDF

  • Underline and strike through text

  • Squiggle text

  • Erase highlight marks or draw something
