How to Add Annotations in PowerPoint: The Complete Step-by-Step Guide

This blog explains how to add real-time annotations in PowerPoint presentations using tools like the pen, highlighter, and laser pointer to make slides more interactive and engaging. It provides step-by-step guidance on drawing, emphasizing key points, and improving audience engagement during a live slideshow. It also highlights how to save and export annotated slides, making it useful for collaboration, meetings, and post-presentation sharing.

Introduction

Whether you are leading a boardroom discussion, teaching a class, or walking a client through a proposal, knowing how to add annotations in PowerPoint can completely change how your audience engages with your content. Instead of static slides, you get a live, interactive experience where you can draw, highlight, and emphasise points in real time — all without leaving your presentation.

This guide covers everything: from using the pen and highlighter tools to saving your annotated PowerPoint as a shareable PDF. You will also find keyboard shortcuts, iPad-specific steps, and tips for annotating while presenting on Zoom or Teams.

What Are Annotations in PowerPoint?

A PowerPoint annotation is any mark, drawing, or highlight you add on top of a slide — either before the presentation or live during the slide show. Think of it as writing on a whiteboard, but directly on your slides.

Two Ways to Use Annotation in PowerPoint

• Pre-designed annotations are drawings or callouts you add to slides while building your deck. These become a permanent part of the slide design and are visible every time the presentation runs.
• Real-time annotations are marks you make during a live slide show using the built-in pen and highlighter tools. These are temporary by default, but PowerPoint gives you the option to keep them once the presentation ends — turning your live session into a fully annotated presentation.

Understanding the difference matters because each approach suits a different goal. Pre-designed annotations work well for structured, polished decks. Real-time annotations are ideal for interactive sessions, training, or discussions where audience responses shape what you write.

How to Annotate a PowerPoint Presentation During a Slideshow (Step-by-Step)

This is the core skill. Follow these steps to annotate PPT slides live, directly inside your running slideshow.

Step 1 — Start Your Slide Show

Go to the Slide Show tab and click From Beginning, or press F5. Your presentation will open in full-screen mode.

Step 2 — Open the Annotation Toolbar

Look at the bottom-left corner of your screen. You will see a small floating controls bar. Click the pen icon to open the annotation menu.

Step 3 — Choose Your Annotation Tool

The annotation menu gives you four options:

• Laser Pointer — projects a glowing dot on the slide without leaving any ink
• Pen — draws freehand lines and shapes in your chosen colour
• Highlighter — applies a semi-transparent colour over text or images
• Eraser — removes specific ink marks from the slide

Select the tool that fits what you need at that moment. You can switch between all of them without exiting the slide show.

Step 4 — Annotate Directly on the Slide

Click and drag your mouse (or use your finger on a touchscreen) to draw, underline, circle, or highlight anything on the current slide. Use right-click or the controls bar to change your pen colour or thickness at any point.

Step 5 — Save or Discard Your Annotations

When you press Escape or end the slide show, PowerPoint will ask: “Do you want to keep your ink annotations?”

• Click Keep to save all marks to the slides — this creates an annotated PowerPoint you can share directly.
• Click Discard to remove all marks and return to the clean original.

If you select Keep, every annotation becomes an embedded drawing object on its respective slide.

PowerPoint Annotation Tools Explained: Pen, Highlighter, and Laser Pointer

PowerPoint gives you three core annotation tools, each with a distinct purpose. Knowing when to use which one is what separates a smooth, confident presenter from someone fumbling mid-slide.

The Pen Tool — Freehand Drawing and Underlining

The pen tool is your go-to for freehand drawing during a presentation. Use it to:

• Circle a key figure or data point
• Underline an important phrase
• Draw arrows pointing to a specific area
• Write short notes or labels directly on the slide

You can customise the color (from a full color picker) and the thickness (thin for detail, thick for emphasis). A thick red circle around a critical number immediately pulls every eye in the room.

The Highlighter Tool — Emphasising Without Covering

The highlighter lays a semi-transparent colour over existing content. It is ideal when you want to draw attention to text or a chart element without obscuring it. Use it to:

• Mark key sentences in a quote
• Highlight a specific row in a data table
• Emphasise a label within a diagram

Unlike the pen, the highlighter does not draw defined shapes — it is purely for marking areas of the slide.

The Laser Pointer — Guide Attention Without Leaving Ink

The laser pointer is the one annotation PowerPoint feature that leaves no mark on the slide. It projects a glowing coloured dot (red, green, or blue) that follows your cursor, guiding your audience’s attention without adding any permanent ink.

To activate it during a slide show:

• Click the pen icon in the controls bar
• Select Laser Pointer
• Move your mouse — the dot follows your cursor across the slide

The laser pointer is especially useful when you want to direct attention to a chart element, figure, or image without writing on the slide. It keeps the slide visually clean while giving you full control over audience focus.

Tip: You can also hold Ctrl and press the left mouse button during any slide show to instantly activate the laser pointer — without opening the annotation menu at all. Mac users can use Cmd+ Click. 

How to Adjust Colour and Thickness

During a live presentation, right-click anywhere on the slide and go to Pointer Options. From here you can:

• Switch between the pen and the highlighter
• Select a new ink colour
• Adjust the pen line thickness

Changing these settings takes only a few seconds and does not interrupt the flow of your presentation.

Keyboard Shortcuts for Annotations in PowerPoint

Switching tools via the controls bar takes a few clicks. PowerPoint Keyboard shortcuts let you move between annotation modes instantly, keeping your presentation rhythm intact.

Memorise Ctrl + P (pen) and Ctrl + A (cursor) at a minimum — or ⌘+P and ⌘+A on Mac. Those two shortcuts alone will dramatically speed up your annotation workflow during any live session. 

Mac users note: fewer slideshow annotation shortcuts are available on Mac; the pen and cursor shortcuts work identically, but the highlighter and eraser require the controls bar rather than a keyboard shortcut.

How to Switch Between Annotation Tools Seamlessly During a Presentation

One of the most common mistakes when annotating PPT slides is fumbling between tools mid-presentation, which breaks focus and flow. Here is how to stay smooth:

• Lead with keyboard shortcuts. They are faster than clicking the toolbar and keep your eyes on the audience, not the screen.
• Pre-decide your tool order. Before the session, consider which slides need highlighting vs freehand drawing.
• Use the eraser strategically. Remove exploratory scribbles while keeping useful annotations.
• Right-click for the fastest menu. A right-click during the slide show opens a context menu with direct access to all pointer options.

How to Annotate a PowerPoint on an iPad

To annotate PPT on iPad, the process is even more intuitive than on a desktop, because the touch interface makes drawing natural and precise.

Steps to Annotate PPT on iPad

• Open your presentation in the Microsoft PowerPoint app on your iPad.
• Tap Slide Show to enter presentation mode, or tap the three-dot menu and select Presenter View.
• During the slide show, tap the pen icon in the bottom-left corner.
• Choose your tool — Pen, Highlighter, or Laser Pointer.
• Use your finger or Apple Pencil to draw directly on the slide.
• When you end the slide show, tap Keep to save your annotated presentation, or Discard to remove all marks.

Apple Pencil Advantage

If you are using an Apple Pencil, annotating ppt on iPad feels closest to writing on paper. The precision and pressure sensitivity make it ideal for writing shorthand notes, signing off on slides, or marking up detailed diagrams during a client review.

Note: Make sure you are running the latest version of PowerPoint for iPad. Some features — like the full colour picker and line thickness control — are only available in updated versions.

How to Annotate in PowerPoint When Presenting on Zoom or Teams

Annotating live while screen-sharing on Zoom or Microsoft Teams requires one extra step: making sure you share the right window. Here is the correct approach for each platform. If you need a broader overview of presenting PowerPoint online, our guide on broadcasting PowerPoint online covers the full setup in detail.

Presenting and Annotating on Zoom

• Launch your presentation in Slide Show mode in PowerPoint first.
• In Zoom, click Share Screen and select the slide show window (not the PowerPoint editor window).
• Use PowerPoint’s built-in pen and highlighter tools as normal — all marks are visible to attendees in real time.

Important: Do not use Zoom’s own annotation toolbar if you want to save your marks. Zoom annotations float at the OS level and cannot be exported back into the PowerPoint file.

Presenting and Annotating on Microsoft Teams

• In a Teams meeting, click Share and choose Window, then select the PowerPoint slide show window.
• PowerPoint’s full annotation toolbar works normally in this mode.
• If you want a blank canvas for brainstorming alongside your slides, Teams also integrates with Microsoft Whiteboard as a companion tool.

For both platforms, starting PowerPoint in slide show mode before sharing ensures your audience only sees the presentation — not your toolbar, taskbar, or editing interface.

How to Save and Export Your Annotated PowerPoint as a PDF

Once your session ends and you choose to keep your marks, you have an annotated PowerPoint file with all drawings embedded as slide objects. Sharing the .pptx file works perfectly, but exporting to PDF is often cleaner for client distribution or archiving.

Steps to Export an Annotated Presentation as PDF

• Go to File > Export > Create PDF/XPS
• Click Options before saving
• In the Options dialog, check “Include comments and ink markup.”
• Click OK, name your file, and click Publish

Your PDF will include every annotation — highlights, pen drawings, circled figures — exactly as they appeared on the slides during the session.

Tip: An annotated presentation exported to PDF is especially useful after client meetings, training sessions, or workshops. It captures the live discussion visually, giving every participant a record of what was emphasised, agreed on, or flagged — without needing a separate written summary. For a full walkthrough on export settings and formatting options, see our guide on how to save PowerPoint as a PDF.

Why Annotations Make Your Presentations More Effective

Knowing how to annotate a PowerPoint is one skill. Understanding why it works helps you use it confidently and consistently.

They Direct Attention Instantly

A well-placed circle or underline tells your audience exactly where to look — no verbal instruction needed. Annotations in PowerPoint essentially act as a virtual pointer that leaves a visible trace, ensuring attention stays on the right spot even as you continue speaking.

They Make Complex Ideas Easier to follow.

When you are explaining a multi-step process, a data trend, or a diagram with many parts, drawing through it live is far more effective than describing it. Real-time annotation lets you walk the audience through complexity step by step — at their pace, not a pre-set animation speed.

They Create a Record of the Discussion

Unlike verbal conversations, an annotated presentation captures what was discussed, decided, or flagged as important. Exporting it as a PDF gives every stakeholder a visual record of the session — especially valuable after sales calls, project reviews, or team training.

They Signal Confidence and Engagement

Presenters who annotate live come across as more in control of their material. Using the PowerPoint annotate tools mid-presentation shows fluency with both the subject and the tool. It is the difference between reading a script and having a genuine conversation with your audience.
