How to Add Alt Text in PowerPoint: A Step-by-Step Guide

Adding alt text in PowerPoint is one of those small tasks that can make a world of difference for accessibility. It’s the digital equivalent of opening a door for someone with a big smile. Alt text provides a brief description of images, shapes, and graphics within a presentation, allowing screen readers to convey this visual information to visually impaired users. Whether you’re presenting data or showcasing a vibrant image, adding alt text ensures everyone can appreciate your hard work.

How to Add Alt Text in PowerPoint: A Step-by-Step Guide

We get it—it might sound a bit daunting if you’ve never done it before. Don’t worry! Incorporating alt text is easier than you think and won’t take a lot of time. In PowerPoint, you have the option to type the description yourself, let PowerPoint generate it, or mark the object as decorative if it’s purely for aesthetic purposes. This not only helps with accessibility but also encourages more thoughtful and inclusive communication in our presentations.

Let’s face it, navigating accessibility features can sometimes feel like learning a new language. Think of alt text as a translator that bridges the gap between visuals and descriptive words. By spending just a few extra minutes adding alt text, we can transform our presentations, making them inclusive and accessible for everyone. It’s a small step that truly reflects our commitment to inclusivity.

Fundamentals of Alt Text

Adding alt text to images in PowerPoint is essential for enhancing accessibility. We will cover why alt text matters for inclusive design and provide tips for crafting effective descriptions.

Importance of Alt Text for Accessibility

Alt text allows screen readers to convey the content of images to visually impaired users. It’s more than just a text description; it provides context that might otherwise be missed.

For example, when we insert an image, those using screen readers will understand its purpose through our alt text.

Key benefits include:

  • Ensuring equal access to information
  • Enhancing the user experience
  • Making content searchable and easily navigable

By using alt text, we make sure no one is left out, showcasing our commitment to accessibility.

Best Practices for Writing Effective Alt Text

Writing effective alt text involves being concise yet descriptive. We should avoid unnecessary details but accurately describe the image’s purpose.

Tips for writing alt text:

  • Be specific: Describe what the image shows in simple, clear language.
  • Keep it concise: Aim for one or two sentences.
  • Include context: Explain the image’s relevance to the surrounding content.

For instance, if we add a pie chart demonstrating sales growth, instead of just saying “chart,” we might write, “Pie chart showing a 20% increase in sales for Q1 2024.”

Following these best practices ensures our alt text is both efficient and informative.

Adding Alt Text in PowerPoint

Adding alt text to images and objects in PowerPoint is essential for improving accessibility. It benefits users with visual impairments and enhances the overall usability of our presentations. Let’s explore how to do this on both PC and Mac versions of PowerPoint, along with utilizing automatic features and the Alt Text pane.

Step-By-Step Instructions for PowerPoint on PC

First, open your PowerPoint presentation. Select the image or object for which you want to add alt text. Go to the “Format” tab on the ribbon and click “Alt Text”. Alternatively, right-click the object and choose “Edit Alt Text” from the dropdown menu.

Once the Alt Text pane appears, enter a concise description in the text box. Describe what’s visible in the image as clearly as possible. If the image is purely decorative, check the “Mark as decorative” box. This tells screen readers to skip over it, enhancing the user experience.

For those who prefer automation, PowerPoint offers an “Generate a description for me” button. This feature uses AI to automatically generate a description, which we can then edit or approve based on its accuracy.

Adjusting Alt Text in PowerPoint for Mac

On a Mac, the process is quite similar. Select the image or object, then click the “Format Picture” tab on the ribbon. From there, click “Alt Text”.

In the Alt Text pane, type a brief, meaningful description. Again, if the image doesn’t contribute to the content, mark it as decorative. The option to “Generate a description for me” is also available on Mac, providing an automated alternative to manual entry.

Remember to review and, if necessary, adjust any generated text to ensure it accurately conveys the essential information to users relying on screen readers.

Utilizing the Alt Text Pane and Automatic Features

The Alt Text pane is a powerful tool in PowerPoint’s accessibility arsenal. It’s accessible by right-clicking an image and choosing “View Alt Text”, or through the “Format” tab.

A major plus for us is the “Generate a description for me” feature. It can save time, though we must review any autogenerated descriptions for accuracy. Adding an effective alt text enhances our presentations by making them accessible to everyone.

Decorative images can be marked as such to avoid unnecessary clutter for screen readers. Open the pane, review the description, and check the “Mark as decorative” box if the image is not essential. This ensures a seamless experience for all viewers.

Advanced Alt Text Techniques

Mastering advanced alt text techniques means effectively handling complex images and knowing when to mark images as decorative. These strategies improve accessibility for those with visual impairments and enhance the overall user experience.

Working with Complex Images like Charts and SmartArt

Complex images, such as charts and SmartArt graphics, demand detailed descriptions. When you right-click the object and choose Format Picture, you’ll see options for adding alt text. First, describe the object, providing a concise and clear explanation of what the image represents. For example, a bar chart showing sales data over the year:

Month Sales Change
January $5000 +10%
February $6000 +20%

It’s important to capture the trends and significant data points succinctly so users with visual impairments can understand the contents. For SmartArt graphics, explaining the relationships or processes depicted can be crucial. For example, if the SmartArt shows a project timeline, describe the key milestones and their significance.

Marking Images as Decorative When Appropriate

Not all images add essential information to your presentation. Some are purely decorative and don’t require alt text. In such cases, marking these images as decorative helps screen readers bypass them, allowing users to focus on critical content.

To mark an image as decorative, select the image, then in the Alt Text pane on the right, check the box labeled Mark as decorative. For example, borders or background images often don’t need descriptions. This can improve accessibility by keeping the information streamlined and relevant.

Using these advanced techniques can significantly enhance the user experience for people with visual impairments, making your presentations more inclusive and effective.

Verifying Accessibility in Your Document

Ensuring our PowerPoint presentations are accessible is crucial. The Accessibility Checker is a powerful tool that runs automatically while we work. It scans for accessibility issues and provides suggestions for resolving them.

To manually run the Accessibility Checker, we go to Review > Check Accessibility. This will open a pane where we can see all the issues detected.

For effective use, we also need to pay attention to Alt Text for images and other non-text elements. When we add or change alt text, it helps describe the significance of digital images to those who can’t see them. Here’s a simple way to add alt text:


1. Select the image.

2. Go to **Format** > **Alt Text**.

3. In the Alt Text pane, write a description.

It’s also beneficial to check how these documents will appear on web pages. Ensuring alt text is meaningful means our content is more inclusive for everyone.

We often make edits on multiple images together. We can do this by grouping images:


1. Shift-click to select images.

2. Use **Home** > **Arrange** > **Group**.

3. Add a collective alt text.

Example Description for Grouped Images:

“A cat and mouse engaged in a playful chase.”

If we find ourselves needing to update suggestions from the accessibility checker, we can always revisit the steps and make necessary changes. This ensures that all our PowerPoint presentations remain accessible and inclusive.
