About this tool
YouTube thumbnails must be 1280 x 720 pixels (16:9) and under 2 MB. This tool resizes and crops any picture to that exact size and compresses it automatically to stay within the limit.
Pick Crop to fill for a full-frame thumbnail. Keep faces and text away from the bottom-right corner, where YouTube places the video length badge.
Everything runs in your browser. Nothing is uploaded.
