Adding alt text to images in Microsoft Word is a simple yet crucial step to ensure your documents are accessible to everyone, including those who rely on screen readers. Whether you're preparing reports, creating educational material, or just want to make sure your content is inclusive. Understanding how to add alt text is essential. Let's walk through the process, and you'll be adding alt text descriptions like a pro in no time.
Why Alt Text is Important
Alt text, short for alternative text, is a brief description that you can add to an image in a document. This text is read aloud by screen readers used by visually impaired individuals, allowing them to understand the context of the image within the document. Beyond accessibility, alt text also plays a role in SEO when documents are published online.
Think of alt text as the voice of an image. It describes what's in the picture and, importantly, its purpose. Imagine browsing the web with images turned off or using a screen reader. That's where alt text becomes your guide. It's the story behind the picture that provides context and meaning.
Starting with the Basics: Inserting an Image
If you're new to Microsoft Word, or perhaps just need a refresher, let's quickly recap how to insert an image into your document. After all, we need an image to add alt text to!
- Open your document: Start by opening the Word document where you want to add an image.
- Go to the Insert tab: Click on the 'Insert' tab in the ribbon at the top of the screen.
- Select Picture: Click on 'Pictures' to upload an image from your computer. You can also choose 'Online Pictures' to insert an image from the web.
- Choose your image: Browse through your files or search for an online image, then click 'Insert' to add it to your document.
With your image in place, it's time to add some descriptive text to ensure everyone can engage with your content fully.
Adding Alt Text to Your Image
Now that you've got your image in the document, adding alt text is a breeze. Here's how to do it:
- Right-click the image: Once your image is in the document, right-click on it to bring up a context menu.
- Select Edit Alt Text: From the menu, choose 'Edit Alt Text.' A sidebar will appear on the right side of your screen.
- Describe the image: In the Alt Text pane, you'll see a text box where you can type a description of the image. Make it concise but informative. For example, if the image is of a sunset over a beach, you might write, "A vibrant sunset over a sandy beach with waves gently lapping the shore."
- Close the pane: Once you've added your description, you can close the Alt Text pane. Your alt text is automatically saved with the document.
And just like that, you've added alt text to your image! It's straightforward and ensures your document is more accessible.

Writing Effective Alt Text
Writing alt text is more art than science. You want to capture the essence of the image without overloading on details. Here are some tips to ensure your descriptions are effective:
- Be specific and concise: Describe what's important about the image. Avoid unnecessary detail. For example, "A smiling child holding a red balloon" is more useful than "A child."
- Focus on the purpose: Consider why the image is in the document. If it's to show a product, describe the product. If it's to set a mood, convey that in your description.
- Avoid using phrases like "image of" or "picture of": Screen readers already announce that there's an image, so there's no need to repeat it in your alt text.
Effective alt text acts like a guide, leading the reader through your document with clarity and purpose.
Checking Your Document for Accessibility
Microsoft Word includes an accessibility checker that can help you identify areas in your document that might need attention. It's a helpful tool to ensure that not only your images but your entire document is accessible. Here's how to use it:
- Go to the Review tab: In the ribbon, click on 'Review.'
- Select Check Accessibility: Click on 'Check Accessibility' to open the Accessibility Checker pane.
- Review the results: The checker will highlight issues and give you suggestions on how to fix them. It will point out missing alt text, among other things.
Using the Accessibility Checker is like having an extra pair of eyes ensuring your document meets accessibility standards, making it more inclusive for all users.
Understanding When to Use Alt Text
Not every image needs alt text. Sometimes, images are purely decorative and don't add value to the content. In these cases, you can mark an image as decorative:
- Open the Alt Text pane: Right-click the image and select 'Edit Alt Text.'
- Check Mark as decorative: There's a checkbox for 'Mark as decorative.' Selecting it tells screen readers to skip the image.
By marking decorative images appropriately, you're ensuring that your document remains accessible without overwhelming users with unnecessary information.
Using Advanced Features: Customizing Alt Text
For those who want to get a bit more advanced, Microsoft Word allows you to customize alt text even further. You can add alt text to grouped images or complex diagrams by describing the whole group instead of individual elements.
- Group images: Select multiple images, right-click, and choose 'Group' to treat them as one.
- Add alt text to the group: Right-click the grouped image and follow the same steps as before to add alt text.
This method is particularly useful for charts or diagrams where the overall message is more important than individual components. It keeps your document tidy and informative.

Saving Time with Alt Text Templates

- Create a template document: Draft a document with alt text for common images you use. Save it as a reference.

It's a bit like having a recipe book for your images. You know exactly what to say and when, ensuring your documents are consistent and accessible.
