# How to add or edit alt text on Instagram photos

By HeyMark · Updated October 22, 2026

When you prepare a photo for Instagram, you can add a description for people who use screen readers. You can also edit it after sharing the photo. Here’s where to find the field on a computer and what to check when you finish.

## Before sharing a photo

1. Upload the photo, then choose a filter or edit the image.
2. Select **Next**.
3. Open **Accessibility** and enter the alt text in the field.
4. Select **Share** to publish the photo.

## Edit a photo you’ve already shared

1. Open the photo and select **Options**.
2. Choose **Edit**, then open **Accessibility**.
3. Enter or revise the alt text and select **Done**.

Meta says automatic descriptions use object recognition and that you can replace them. Screen reader users hear the alt text when they access Instagram; it does not appear as the photo caption. For another device, check its steps in [Instagram’s official help](https://www.facebook.com/help/instagram/503708446705527?locale=en_US).
