What it is
Thumbnailr.io is a web tool for YouTube creators making thumbnails from a written brief, a reference image, or a YouTube link. It exports 1280×720 PNG files without a watermark, and the site says a typical run takes about a minute. Up to three reference images or a YouTube thumbnail link can guide the style. You can also add up to three images of faces, products, or shots as the main subject. Edit prompts create a new version from the same project and use one credit per edit. A beta script-generation tool shares the thumbnail balance and uses one credit for each generate, regenerate, or edit. New accounts receive five credits without a credit card, and credits never expire. The Free plan is free; a one-time Credit pack is $1,025, paid once for 25 credits. There is no free trial.
