Auto-fit to 1280×720px for YouTube

What is the YouTube Thumbnail size?

The YouTube Thumbnail size is 1280×720 pixels, an aspect ratio of 16:9. This is the recommended dimension for Video thumbnails on YouTube. Must be under 2MB. Large readable text works best at small sizes. This tool resizes any image to exactly 1280×720px in your browser — you can zoom, reposition, and choose whether to fill the frame (cropping edges) or fit the whole image (adding whitespace), then download a perfectly-sized PNG.

How to resize an image for YouTube Thumbnail

To resize an image for YouTube: upload your image above, use the zoom and position sliders to frame it inside the 1280×720px area, choose Fill (to crop and fill the whole frame) or Fit (to keep the entire image with white padding), and download. The result is exactly 1280×720px — the correct YouTube Thumbnail size — so it uploads to YouTube without any awkward cropping. Everything happens in your browser, so your image is never uploaded to a server.

Tips for a great YouTube Thumbnail

For the best YouTube Thumbnail: start with a high-resolution image so it stays sharp at 1280×720px, keep important content (faces, text, logos) in the center safe zone, and export as PNG for crisp edges or JPEG for smaller file size. Must be under 2MB. Large readable text works best at small sizes. Using the exact 16:9 ratio prevents YouTube from auto-cropping your image in unexpected ways, which is the most common reason posts look wrong after uploading.
