Why Thumbnail Size Matters
YouTube thumbnails are the first thing viewers see. A sharp, correctly-sized thumbnail can dramatically improve your click-through rate.
The recommended size is 1280×720 pixels at a 16:9 aspect ratio. Thumbnails that don't match this ratio will be cropped automatically by YouTube, often cutting off important text or faces.
Use this free tool to crop your images to the exact 16:9 ratio before uploading. Everything runs in your browser — your images stay on your device.
