YouTube Community Posts Do Not Support Image Custom ALT Text

YouTube Community posts currently do not provide a built in option for creators to add custom ALT text to images. This differs from platforms such as Facebook, Instagram, LinkedIn, Pinterest, and X, which all support image descriptions for accessibility.

Here are the main reasons:

1. Platform design priorities
   YouTube was originally built around video, where accessibility is primarily handled through:
   
   • Closed captions
   • Subtitles
   • Audio tracks
   • Video descriptions
   • Screen reader support for the interface
2. Community posts were added later as a social feature and have fewer accessibility options than videos.
   
3. No creator interface for image descriptions
   When uploading an image to a Community post, YouTube Studio and the mobile app do not include a field where creators can enter alternative text. Since the interface lacks this feature, creators cannot attach custom image descriptions.
4. Reliance on surrounding text
   YouTube expects much of the image context to come from:
   
   • The post text
   • Poll question (if applicable)
   • Related video title
   • Linked content
5. This approach is less effective for users who rely on screen readers than dedicated alt text.
   

Best practices

Until YouTube adds native support, creators can improve accessibility by:

• Describing the important visual information in the post text.
• Mentioning any text that appears inside the image.
• Avoiding images that communicate essential information without also explaining it in the post.
• Ensuring headlines inside graphics are also written in the accompanying post.

For example, if your image headline says:

Journey Through Millions of Years on Historic US Route 6

Your Community post might begin:

Explore prehistoric fossils, dinosaur discoveries, and family friendly exhibits along Historic US Route 6. The accompanying image shows the museum entrance with the Historic US Route 6 shield and the headline “Journey Through Millions of Years on Historic US Route 6.”

Why you should still write ALT text

Even though YouTube Community posts cannot use custom alt text today, it’s still worthwhile to create it because:

• It can be reused on Facebook, LinkedIn, Pinterest, X, and your WordPress site.
• It provides a consistent accessibility description for your image library.
• If YouTube introduces alt text support in the future, you’ll already have descriptions prepared.

For your US Route 6 Happenings workflow, continuing to include ALT text with every social media image is a good practice. It serves all of your other platforms immediately and gives you a ready to use description if YouTube later adds native image alt text support.
