Alt Text
Add image descriptions for accessibility when posting to Instagram, X/Twitter, and Threads.
Alt text provides a text description of your images for screen readers and visually impaired users. Adding alt text makes your content more accessible and can improve search visibility.
Supported platforms
- X/Twitter
- Threads
Adding alt text
- Upload an image to the composer
- The alt text input appears below your media preview
- For carousel posts, each image has its own alt text field below the carousel item
- Write a concise description of what the image shows
Tips
- Describe the content and context of the image, not just its appearance
- Keep it concise — one or two sentences is usually enough
- Skip phrases like "image of" or "photo of" — screen readers already announce that it's an image
