How to Save Ink Annotations After a PowerPoint Slide Show Ends

When you use a pen or highlighter to mark slides during a PowerPoint slide show, those ink annotations disappear by default as soon as you end the show. Many presenters lose valuable feedback, meeting notes, or teaching marks because they do not know where to find the save prompt. PowerPoint includes a built-in option that asks whether you want to keep or discard your annotations when you exit the presentation. This article explains how to enable that prompt and how to manually save ink annotations after a slide show ends.

How PowerPoint Handles Ink Annotations by Default

When you right-click a slide during a presentation and select Pointer Options, you can draw or highlight with a pen, highlighter, or laser pointer. PowerPoint stores these marks only in memory while the show is running. As soon as you press Escape or click End Show, the application erases all ink strokes unless you have changed the default setting.

The default behavior is to discard annotations because most presenters use them as temporary visual aids. However, PowerPoint includes a hidden option under Advanced settings that forces the application to ask if you want to keep the ink. When enabled, a dialog box appears immediately after you end the show, giving you the choice to Keep or Discard.

Enable the Prompt to Save Ink Annotations After a Slide Show

1. Open PowerPoint Options
   Open PowerPoint and click the File tab. In the backstage view, click Options at the bottom of the left pane.
2. Go to Advanced settings
   In the PowerPoint Options dialog, click Advanced in the left navigation list. Scroll down to the Slide Show section.
3. Enable the save prompt
   Check the box labeled Prompt to keep or discard ink annotations. Click OK to save the change.
4. Test the setting
   Open any presentation and start the slide show with F5. Use the pen tool to draw on one or more slides. Press Escape to end the show. A dialog box titled Microsoft PowerPoint appears with two buttons: Keep and Discard. Click Keep to save all annotations to the slides.

After you click Keep, each annotation becomes a permanent ink object on its respective slide. You can move, resize, or delete it just like any other shape. The ink remains even after you close and reopen the file.

Save Annotations Manually During the Slide Show

If you prefer not to change the global setting, you can save annotations mid-presentation using the keyboard. This method is useful when you want to save marks for a specific slide without keeping annotations from other slides.

1. Draw your annotations
   During the slide show, use Ctrl+P to activate the pen or Ctrl+I for the highlighter. Draw or write on the slide as needed.
2. Save annotations immediately
   Press Ctrl+S on the keyboard. A brief message appears at the top of the slide: Annotations saved. The ink strokes are now part of the slide object.
3. Continue the presentation
   Press the spacebar or click to advance to the next slide. The saved annotations remain visible on the current slide. Repeat Ctrl+S on any other slide where you want to keep ink.

This method does not require any change to PowerPoint options. It works in PowerPoint 2016, 2019, 2021, and PowerPoint for Microsoft 365 on Windows. The shortcut also works in PowerPoint for Mac, where you press Command+S instead.

Export Ink Annotations as a Separate File

PowerPoint does not have a native export option for ink annotations alone. However, you can save the entire presentation as a PDF or image set that includes the marks. This is the closest equivalent to exporting annotations.

1. Save the presentation with annotations kept
   After the slide show ends, click Keep in the prompt dialog. The ink strokes become permanent slide objects.
2. Export to PDF
   Click File > Export > Create PDF/XPS Document. Click Options and ensure Publish what is set to Slides. Click OK and then Publish. The resulting PDF shows all ink annotations.
3. Export as images
   Click File > Save As. Choose PNG or JPEG from the Save as type list. Click Save. PowerPoint prompts you to export Every slide or Just This One. Every slide creates a separate image file that includes the ink marks.

Common Issues When Saving Ink Annotations

The save prompt does not appear after I enable it

This usually happens when you have multiple presentations open. The setting applies per application session, not per file. Close all PowerPoint windows and restart the application. Open your presentation again and run the slide show. The prompt should now appear.

Ink annotations disappear after I close and reopen the file

If you clicked Discard or pressed Escape without saving, the marks are gone permanently. Re-enable the save prompt and run the show again. Use Ctrl+S during the show as a backup method. If the marks are missing even after clicking Keep, check whether the presentation is set to Read-Only mode. Read-Only files cannot save changes, including ink objects. Save a copy of the file with a new name before starting the slide show.

Ink annotations are not visible in Slide Sorter view

Ink objects are visible only in Normal view and Slide Show view. Slide Sorter view hides all shapes, including ink. Switch to Normal view to see the annotations. If you still cannot see them, zoom in to 100% because very thin pen strokes may be hard to detect at a reduced zoom level.

PowerPoint Save Methods for Ink Annotations: Comparison

Item	Prompt to Keep or Discard	Ctrl+S During Show
How to enable	File > Options > Advanced > Slide Show	No setup required
When it saves	After you end the slide show	Instantly when you press the shortcut
User interaction	Click Keep or Discard in a dialog	No dialog appears
Works for individual slides	Saves all annotations from all slides	Saves only the current slide
Compatibility	PowerPoint 2010 and later	PowerPoint 2016 and later

PowerPoint does not offer a single-click export for ink annotations alone. The two methods above are the only ways to keep ink marks after a slide show ends. Use the prompt setting when you want to save everything at once. Use Ctrl+S when you need selective control over which slides keep their annotations.
