YouTube Thumbnail Resizer

Create perfectly sized YouTube thumbnails with our free YouTube thumbnail resizer.
Upload any image and instantly generate thumbnails at YouTube’s recommended dimensions: 1280×720 pixels (standard), 1920×1080 (HD), and 640×360 (SD).

Why thumbnail size matters: YouTube recommends thumbnails be exactly 1280×720 pixels with a 16:9 aspect ratio. Images below this resolution appear blurry in search results, suggested videos, and mobile feeds. Our thumbnail resizer ensures your image meets these requirements while preserving maximum quality.

Size previews: See how your thumbnail appears at actual YouTube sizes – search results (360px), sidebar suggestions (168px), and mobile feed (320px). Make sure text remains readable and key elements stay recognizable even at small sizes.

Fit options: Choose Cover mode to fill the frame completely (may crop edges), Contain mode to fit the entire image with letterboxing, or Original mode for pixel-perfect control.

I switched from my previous platform to Beamly years ago, and I’ve never looked back!

I was looking for a platform I could easily configure myself without spending hours on it, and Beamly has been exactly that.
