Resize Image to 1280×720 (YouTube Thumbnail)

1280×720 is the size YouTube specifies for a custom video thumbnail — 16:9, minimum 1280 pixels wide, and the frame that shows up in search, on the watch page and across every recommendation rail. YouTube also rejects thumbnail files over 2 MB, which trips people up when they export a huge PNG; sizing to a clean 1280×720 keeps the file small enough to upload on the first try while staying sharp when it's scaled up to fill a TV. This tool crops your artwork to that exact frame on your device, so a thumbnail you haven't published yet never leaves your machine.

Good to know

Outputs exactly 1280 × 720 pixels — YouTube's recommended 16:9 custom thumbnail size.

A 1280-wide export comfortably clears YouTube's 1280 px minimum while keeping the file under the 2 MB thumbnail limit.

"Cover" fit fills the whole 16:9 frame and trims overflow, so there are no bars around your thumbnail art.

Keep faces and title text away from the very bottom-right corner, where the video's duration badge sits.

Also the right size for a 720p video still, a blog hero or any 16:9 slide.

Runs entirely in your browser — no upload, no account, nothing stored.

Frequently Asked Questions

What size does YouTube want for a thumbnail? ▼

YouTube recommends 1280×720 pixels, with a minimum width of 1280 and a 16:9 aspect ratio. That single size scales cleanly everywhere the thumbnail appears — search results, the watch page, mobile and full-screen TV — so it's the safe default for a custom thumbnail.

Why does my thumbnail upload keep getting rejected? ▼

The most common reason is file size: YouTube caps thumbnail images at 2 MB. A 1280×720 JPEG almost always lands well under that, whereas a full-resolution PNG export can blow past it. Sizing to 1280×720 and exporting as a JPEG fixes the vast majority of rejected uploads.

Where should I avoid putting text on a 1280×720 thumbnail? ▼

Keep key text and faces out of the bottom-right corner — that's where YouTube overlays the video's duration timestamp on the thumbnail. Some layouts also get lightly cropped on certain surfaces, so leaving a little margin around the edges keeps everything readable.

Is my thumbnail uploaded to a server to resize it? ▼

No. The resize runs on a canvas in your browser, so your thumbnail art stays on your device — handy when the video isn't public yet.
