What Is YouTube Thumbnail Resizer?

The YouTube Thumbnail Resizer produces a thumbnail at the 1280x720 that YouTube asks for, plus Full HD and channel avatar options. It is aimed squarely at the platform rules that decide whether your video gets clicked, starting with meeting the minimum resolution. JPG is offered as the recommended format because it keeps the file comfortably under the 2 MB upload limit.

Who Uses the YouTube Thumbnail Resizer?

YouTubers, video editors, course creators and agencies use it to make sure a video is not skipped in search results for having a low-resolution or oversized thumbnail.

How to Use the YouTube Thumbnail Resizer

  1. Drop the thumbnail image into the resizer.
  2. Choose Thumbnail HD 1280x720, Full HD 1920x1080 or Channel avatar 800x800, or set your own width and height.
  3. Select JPG for the smallest upload under the 2 MB limit, or PNG or WebP, then resize and download.
