YouTube thumbnail dimensions
YouTube recommends thumbnails at 1280×720 pixels (16:9 aspect ratio). This size ensures your thumbnail looks sharp on all devices — from mobile to TV. Using a smaller image can result in a blurry or pixelated thumbnail.
This free tool resizes your image to exactly 1280×720. Fill mode is used by default so your image covers the full frame — if your source has a different aspect ratio, the edges may be cropped. All processing happens in your browser.
