Adding alt text to your images on the Buffer mobile app

Currently, it is possible to add alt text to static images scheduled to X/Twitter, Mastodon, LinkedIn, Pinterest, Threads, and Facebook through Buffer.

📝 Looking for the web browser version of the "Adding alt text to images" article?

When you have added an image to your post in the Buffer composer (Learn more about scheduling posts on the Buffer mobile app here), tap Add Description to add your alt text and then tap Done to save the changes. From there, you can finish scheduling your post.

While we recommend using less than 200 characters to align with accessibility best practices, the character counts for alt text in Buffer are as follows:

  • Pinterest - 500 characters
  • LinkedIn - 300 characters
  • X/Twitter, Mastodon, Threads, Facebook, Bluesky, Instagram - 1,000 characters

Click "Add Description" to add alt text
