Instagram Alt Text Guide: How to Add or Edit Image Descriptions

Balasahana Suresh
Instagram allows users to add alt text (alternative text) to their photos, helping visually impaired users understand images. Alt text also improves SEO and post discoverability.

1. What is instagram Alt Text?

  • Alt text is a written description of an image that screen readers use for visually impaired users.
  • Instagram automatically generates alt text using AI, but users can customize descriptions for clarity.
  • Helps enhance accessibility and increase engagement, as it provides context for all users.
2. How to Add Alt Text When Posting a New Photo

On mobile (iOS & Android)

Open Instagram and tap + to create a new post.

Upload your photo or video.

Tap Next → Advanced Settings → Write Alt Text.

Enter a detailed description of the image.

Tap Done and then Share your post.

Tip: Describe key elements, colors, context, and any text in the image.

3. How to Edit Alt Text on an Existing Post

Open the post you want to edit.

Tap the three dots () → Edit → Edit Alt Text.

Update the description and tap Save.

This allows you to improve accessibility for older posts without reposting.

4. Best Practices for Writing Alt Text

  • Be clear and concise, 1–2 sentences is usually enough.
  • Include important details like people, objects, actions, or text in the image.
  • Avoid repeating phrases like “image of” — screen readers already indicate it’s a picture.
  • Use keywords naturally to improve post discoverability.
Example:

  • Instead of: “Picture of a dog.”
  • Better: “Golden retriever wearing a red bandana, sitting in a sunny park with a frisbee nearby.”
5. Benefits of Using Alt Text

  • Accessibility: Helps visually impaired users understand your posts.
  • SEO Advantage: search engines can index your images better.
  • Engagement: More people can interact with your content when it’s descriptive.
