Drop a photo onto the page. For thumbnails, pick a source at least 1280×720 — ideally 1920×1080 or larger for clean downscaling.
The frame is locked at 16:9 with a 1280×720 output. Drag and scale until the key subject sits where you want it.
The size badge confirms '1280×720 px' before download — exactly the resolution YouTube recommends for thumbnails.
Hit Download and choose JPG to keep the file well under YouTube's 2 MB thumbnail limit, or PNG/WebP for the highest quality.
Google's own YouTube Help recommends 1280×720 as the minimum thumbnail width, with a 16:9 ratio. It's the smallest size that stays sharp across the YouTube web player, the mobile app's video card, and the search result thumbnails.
720p is 1280×720 pixels (HD). 1080p is 1920×1080 (Full HD). Both are 16:9. 1080p has 2.25× more pixels, so it looks sharper on large screens — but YouTube downscales thumbnails for many surfaces, so 720p is often enough.
Yes — YouTube accepts thumbnails up to 2560×1440 as long as you stay under 2 MB. Use our Crop to 16:9 tool to pick a larger output. Many creators use 1920×1080 for extra sharpness on Retina displays.
YouTube's hard cap is 2 MB per thumbnail. At 1280×720, a quality-80 JPG is typically 100–300 KB, so you have plenty of headroom. If your file is too large, re-export as JPG instead of PNG.
On the YouTube video page, the thumbnail is displayed at roughly 480×270 to 640×360, so a 1280×720 image is downscaled — that downscaling actually keeps it crisp. On large grid views (TVs, full-screen browsing), 1920×1080 looks slightly sharper.
