How it works

- Leave the size at 1280 × 720, or change it.
- Check the preview, press the button and download the resized thumbnail.
Get a 1280 × 720 image, the size YouTube recommends for video thumbnails. It is scaled and cropped to 16:9 without distortion, and never leaves your device.
Files stay on your device. Free, with no sign-up.
Preparing preview…
Nothing left your device.
YouTube recommends thumbnails of 1280 × 720 pixels (16:9) and a file under 2 MB. An image at exactly that size is displayed sharply everywhere, from phone screens to TVs.
If your saved thumbnail is bigger than 2 MB, save it as JPG or run it through Compress Image with a limit such as 1 MB.
YouTube asks for under 2 MB. A 1280 × 720 JPG is normally far below that; if yours is not, use Compress Image with a 1 MB limit.
By default the edges are trimmed evenly to make it 16:9. Choose "add white margins" if you would rather keep the whole picture and fill the rest.
No. It is scaled without distortion. If the shape of your picture is different from the target, the tool either crops the edges or adds white margins, depending on the page, so faces and lettering keep their proportions.
Yes. After resizing, run the result through Compress Image with the size limit your form gives, for example 50 KB. Doing it in that order gives the best quality.
No. Everything happens inside your browser, on your own device. Your files are never sent to a server, and you can confirm that in your browser's network tab. Close the tab and they're gone.
Each file can be up to 100 MB, and up to 300 MB in total. Because the work happens on your device, very large files depend on your available memory. A desktop browser handles them best.
