Resize Image for YouTube Thumbnail
YouTube thumbnails should be 1280×720 px (16:9) and under 2MB. Well-compressed thumbnails load faster for viewers on slow connections. Use our free tool to compress your photo for YouTube — works on mobile and desktop. Keep thumbnails between 100–500KB for the best quality-to-speed ratio. All processing happens locally in your browser.
What You Need to Know
YouTube thumbnails are one of the most important factors in click-through rate. A blurry or slowly-loading thumbnail costs views. At 1280×720px and under 500KB, your thumbnail loads instantly even for viewers on slow connections, and the text overlay remains sharp and readable at small display sizes.
