Thumbnail Size Resizer for YouTube – 1280x720 JPG Under 2MB (Private, No Upload)

This free thumbnail size fitter turns any picture into a 1280 x 720 pixel JPG, the 16:9 size that video platforms commonly recommend for thumbnails (check the current rules in the platform's help pages, because they can change).

Pick an image from your device, choose how it should fit, and download the result. You never need an account, and this tool does not connect to any video site.

There are two ways to fit a picture that is not already 16:9. Fill the frame crops the picture so it covers the whole thumbnail, and you can drag it to choose which part stays and zoom in for a tighter look.

Fit with padding keeps the whole picture visible and fills the empty sides with white, black or a blurred copy of the picture itself. Padding is useful for vertical photos or screenshots you do not want to crop.

2 MB is the safe size that works everywhere, including uploads from the mobile app; desktop uploads may now allow larger files, so check YouTube Help.

The tool saves a JPG at quality 0.92 first and lowers the quality step by step until the file is 2 MB or smaller, then shows the final file size.

Very detailed images may still be large, so a simpler picture or a smaller source can help.

Your image is never uploaded. Everything happens in your browser on your own device, and saving re-encodes the picture, which removes hidden camera data such as GPS location.

Photos over 50 MB or 40 megapixels are skipped to keep your device responsive. A small preview shows roughly how your thumbnail looks as a tiny list image.

Check that faces and big words are still readable at that size, and keep important text away from the edges. Only use pictures you made or have the right to use. YouTube is a trademark of Google LLC.
