Overview
- X confirmed the change through a post by Jonah Katz, its mobile engineering lead, announcing users can now attach up to 20 photos or videos to a single post.
- The new cap replaces the decade-old four-file limit that had forced many users to post threads or multiple posts to share large photo sets.
- The feature is live on X's web interface and is arriving on mobile through the latest app update, with staged rollouts meaning some users will see it later than others.
- Users can enable the mobile option by updating the X app to the newest version and then using the camera or upload controls to attach multiple files in one post.
- The change joins other 2026 product moves such as X Money and XChat and could reduce threaded posts, simplify visual storytelling for creators and streamline marketing workflows.
