How to use the download
For Shorts, YouTube recommends a 9:16 image. Its current desktop instructions say a verified account can upload it under Content → Shorts → Thumbnail in YouTube Studio.
Use 16:9 for a standard YouTube video. Square is a general design export. YouTube’s native title and thumbnail A/B testing is not available for Shorts.
