About this tool
A YouTube thumbnail is usually 1280 by 720 pixels (16:9) and must stay under 2 MB. Add your image and this tool crops or fits it to that exact size, then compresses it until it is under the limit.
Output: 1280×720 pixels, JPEG or WebP, kept under 2 MB. If the picture is not 16:9, choose Crop to fill, or Fit inside with a blurred background to keep everything visible.
