PowerPoint Slideshow With Pen Tool: How to Save Ink as Annotation

You draw on your slides during a presentation using the Pen tool in PowerPoint. When you exit the slideshow, the ink marks disappear and you lose all your handwritten notes. This happens because PowerPoint treats ink drawn during a slideshow as temporary unless you explicitly save it. This article explains how to keep those annotations permanently attached to your slides so you can review, print, or share them after the presentation.

Why Pen Ink Disappears After a PowerPoint Slideshow

When you use the Pen tool during a slideshow, PowerPoint creates the ink marks in a temporary overlay layer. This layer exists only while the slideshow is active. As soon as you press Escape or reach the end of the presentation, PowerPoint discards this overlay by default. The application assumes that most ink drawn during a live presentation is spontaneous and not meant to be saved.

The ink strokes are not lost if you take a specific action before leaving the slideshow. PowerPoint provides two built-in commands to promote temporary ink to permanent annotation objects. Once saved, the ink behaves like any other shape on the slide. You can move it, resize it, change its color, or delete it in Normal view. The saved ink is also visible when you export the presentation to PDF or print the slides.

What Happens if You Do Not Save Ink

If you exit the slideshow without saving, the ink is gone. There is no undo command that can restore it. The AutoRecover feature does not capture temporary ink strokes because they are not part of the slide file until you explicitly save them. This is why presenters who rely on pen annotations for feedback sessions or classroom teaching often lose their work.

Steps to Save Pen Ink as a Permanent Annotation

You can save ink annotations while the slideshow is still running or when you are about to exit. Use one of the following methods depending on whether you want to keep ink on one slide or on all slides you have drawn on.

Method 1: Save Ink on the Current Slide Without Exiting

1. Draw on the slide using the Pen tool
   During the slideshow, click the Pen icon in the bottom-left toolbar or press Ctrl+P to activate the Pen cursor. Draw your annotations on the slide.
2. Right-click the slide
   Press the right mouse button anywhere on the slide to open the context menu.
3. Select Keep Ink
   From the context menu, choose Keep Ink. The ink strokes on the current slide become permanent. The slideshow continues.

Repeat this process for each slide that has ink you want to save. Ink on slides where you did not select Keep Ink will be discarded when you exit the slideshow.

Method 2: Save Ink on All Slides When Exiting

1. Press Escape to exit the slideshow
   PowerPoint displays a dialog box with two options: Keep or Discard.
2. Click Keep
   All ink strokes drawn on every slide during the current slideshow are saved as permanent annotations. Ink is saved on each slide you drew on.

If you do not see this dialog box, the feature is disabled in PowerPoint Options. See the next method to enable it.

Method 3: Enable the Prompt to Keep Ink on Exit

1. Open PowerPoint Options
   Click File in the ribbon, then Options at the bottom of the left pane.
2. Go to the Save tab
   In the PowerPoint Options dialog, select Save from the left navigation.
3. Check the prompt setting
   Under Save presentations, check the box labeled Prompt to keep ink when exiting. Click OK.

Now whenever you exit a slideshow where ink was drawn, PowerPoint will ask whether to keep or discard the ink. This setting applies to all presentations.

Method 4: Save Ink Using a Keyboard Shortcut

1. Press Ctrl+S during the slideshow
   This saves the ink on the current slide and immediately exits the slideshow. PowerPoint does not show a confirmation dialog. The ink on all slides you have drawn on is saved.

This is the fastest method when you want to end the presentation and keep all annotations at once. Be aware that Ctrl+S also saves any changes you made to the slide content during the slideshow, such as typing in text boxes.

Common Problems When Saving Pen Ink

Keep Ink Option Is Grayed Out in the Context Menu

The Keep Ink option is only available when you have drawn at least one ink stroke on the current slide. If you right-click a slide where you did not draw, the option is disabled. Draw a small mark first, then right-click and select Keep Ink.

Ink Is Saved but Looks Different in Normal View

Pen ink drawn during a slideshow uses the default pen color and thickness defined in the slideshow toolbar. When saved, the ink becomes a freeform shape. Its appearance may shift slightly if the slide zoom level in Normal view differs from the slideshow resolution. This is normal and does not affect printing or export.

Ink Disappears After Saving and Reopening the File

If you saved ink using Keep Ink or the prompt dialog, the ink is part of the slide file. If the ink disappears after reopening, check whether you saved the presentation file after exiting the slideshow. The ink is stored in the .pptx file only after you save the document. Press Ctrl+S in Normal view after the slideshow to write the ink objects to disk.

Pen Tool Does Not Appear During Slideshow

The Pen tool is visible only when you move the mouse or touch the screen during the slideshow. It disappears after a few seconds of inactivity. Move the mouse to bring the toolbar back. If the toolbar still does not appear, press Ctrl+P to activate the Pen directly.

Item	Keep Ink (Context Menu)	Ctrl+S During Slideshow
Scope	Saves ink on the current slide only	Saves ink on all slides and exits the show
Slideshow continues	Yes	No, exits immediately
Confirmation dialog	None	None, saves silently
Best use case	Teaching sessions where you draw on one slide at a time	End of a presentation where you want to keep all annotations
Requires enabled prompt	No	No

You can now save your pen annotations permanently in PowerPoint using one of the four methods described above. The next time you present, decide in advance whether you will keep ink on individual slides or all slides at once. For frequent use, enable the prompt to keep ink on exit in PowerPoint Options so you never lose annotations by accident.
