How to resize a YouTube thumbnail

  1. Choose the image you want to use as your thumbnail.
  2. Pick the platform size — YouTube thumbnails are 1280×720 (16:9).
  3. Crop to fill keeps the subject centered and trims the edges; Fit + blurred bars keeps the whole image and fills empty space with a blurred version.
  4. Download the JPG and upload it to YouTube Studio.
