Image tools for YouTube
Size thumbnails to 1280 × 720 and make the subject pop.
A YouTube thumbnail is shown at 16:9, and 1280 × 720 is the usual size to export. PixVibe's image resizer and cropper both have a YouTube thumbnail preset, so a frame grab or photo comes out at the right shape; changing the background color puts a cut-out person or product on a bold, solid color that stands out next to other videos. All three tools run in your browser.
