WThumb is an AI-powered thumbnail maker for YouTube. The name is short for Winning Thumbnail, and it creates custom thumbnails for your videos either by remaking a thumbnail you like or by designing one from a written description.
To recreate a thumbnail, you paste a YouTube link or upload an image. WThumb reads it as a brief, carrying over the layout, hierarchy and energy, while changing everything you name, such as the subject, words and colours. If you have no reference in mind, you can describe the thumbnail you want instead, or pick from ready-made templates for faceless or face-based designs.
You can save a persona once, with your name and a few photos, so that you appear in your thumbnails. If you would rather stay off camera, the faceless option rebuilds the frame without a person. Thumbnails can be made in 16:9 for standard YouTube videos, 9:16 for Shorts, or both, with each version designed for its own frame so nothing important is cropped.
Everything happens on one page in the WThumb Studio. You add a reference, choose a persona or faceless, type the words for the thumbnail and any changes, then press Make. A typical thumbnail is ready in about 30 seconds. You can then press Edit and describe changes in plain words, and every version is kept in your thumbnail history.
Key features include a library of thousands of thumbnails from popular channels with outlier scores showing how far a video beat its channel's usual views. The library can be searched and filtered by tone, topic, style, mood, object or colour, and any thumbnail can be used as a brief. The site also offers free tools such as a thumbnail tester, size checker, downloader, resizer, compressor and colour palette tool.
Pricing: new accounts get 2 free credits with no card required (1 credit is 1 thumbnail or revision). Paid plans are Starter at US$12 per month (40 credits, 1 persona), Creator at US$28 per month (160 credits, 3 personas) and Studio at US$56 per month (400 credits, 10 personas), billed monthly, with a yearly option that saves 25%.
It is suited to YouTubers, Shorts creators, podcasters, gaming channels and small businesses that want click-worthy thumbnails without design skills.
