Version 0.2 of the NoInk script to remove ink annotations from your PowerPoint slide decks is out!

I just released version 0.2 of the NoInk.ps1 Powershell script to remove ink annotations from your PowerPoint slide decks.

When I teach online, and sometimes in presence as well, I use a lot of my Wacom ONE graphic tablet to draw on my PowerPoint slides.
Generally, I save them so I do not lose the annotations during the breaks.

This tool helps you to remove all the ink annotations from all your slides decks automatically so they return clean and ready for the next training.

I wrote this tool in PowerShell and I tried it on Windows 7 x64 SP1 and Windows 10, using PowerShell 5.1 and Office Plus 2013 and Office 2019

This new version includes some nice improvements. I added a couple of optional parameters:

  • ShowAll:  If specified all the objects found in every slide are enumerated but only the objects of type msoInk and msoInkComment are removed
  • DryRun:  If the parameter is specified no objects are deleted

The usage is really simple:

From the PowerShell command line:


  • It removes the Ink Annotations from all the .pptx files found in the current directory.

.\NoInk.ps1 myPresentation.pptx

  • It removes the Ink Annotations from the specified file.

.\NoInk.ps1 C:\Users\mzuppone\Desktop

  • Removes the ink annotations from all the slide decks (.pptx files) found in C:\Users\mzuppone\Desktop

.\NoInk.ps1 C:\Users\mzuppone\Desktop -DryRun

  • All the slide decks (.pptx files) found in C:\Users\mzuppone\Desktop are processed but no shapes are deleted from them

.\NoInk.ps1 myPresentation.pptx -ShowAll

  • Removes the ink annotations from the file myPresentation.pptx and shows all the shapes type found in every slide

Where can I find the script?

You can find it on GitHub at this link:

On GitHub you can find as well a signed copy of the script.

The advantage of using the signed version of the script is that you can execute it without the need to modify the PowerShell execution policies.

Keep an eye on the Releases here:
