Resize Image for YouTube Thumbnail — Free Tool
The exact dimensions YouTube recommends, without Photoshop or Canva.
YouTube recommends thumbnails at 1280×720 pixels with a minimum width of 640 px. A blurry or wrong-sized thumbnail kills your click-through rate before anyone watches your video.

- 3Download the cropped image, then open the Image Resizer.
- 4Resize to 1280 × 720 pixels and download the final thumbnail.
