Your file will be well under 2 MB and ready to upload directly to YouTube Studio.
The ideal YouTube thumbnail size is 1280×720 px (16:9 aspect ratio). Keep it under 2 MB. JPG, PNG, GIF, and WebP are all accepted.
YouTube channel art should be 2560×1440 px. The safe zone visible on all devices is the central 1546×423 px. Keep important text and logos within this safe zone.
Blurry thumbnails are usually caused by uploading a low-resolution image (under 640 px wide) or an oversized file that YouTube has re-compressed heavily. Always start with a 1280×720 source at 85%+ quality.
Free, instant, 100% private. No upload. Works on mobile and desktop.
