How to use YouTube thumbnail maker

  1. Add a picture to use as the background.

  3. Check the preview at 1280 by 720 pixels.
  4. Save the thumbnail, keeping it under YouTube's 2 MB limit.

Why use this tool

The thumbnail is the first thing a viewer sees, and it can decide whether they click. YouTube expects 1280 by 720 pixels and a file under 2 MB. This tool builds a thumbnail in that format, with a title on it, and warns you about the file size.

Tips for best results

  • Use large, bold text with strong contrast so it reads on a phone.
  • Keep the title short, about three to five words.
  • Keep the corner clear, because YouTube puts the video length there.
