WThumb

WThumb is a web tool that remakes proven YouTube thumbnails around your own title, face or faceless style. Start from a link, upload or library pick, or describe the video, and get 16:9 or Shorts 9:16 versions using a credit system.

WThumb is a web-based thumbnail maker built specifically for YouTube creators. Instead of starting from a blank canvas, it works from a reference: paste a link to a thumbnail you admire, upload an image, or pick one from the built-in library, and the tool treats it as a brief. Layout, hierarchy and energy carry over, while the title, subject, colors and props change to fit your own video. Creators without a reference can switch to a prompt mode and simply describe the video. The workflow lives on a single page called the Studio. A user adds a reference, chooses a saved persona or Faceless, types the words that should appear on the thumbnail, adds any change requests in plain language, and presses Make. A persona is created once from a name and a few photos, so the creator's likeness appears in generated thumbnails. Faceless mode rebuilds the frame with nobody in it. Output can be 16:9 for standard videos, 9:16 for Shorts, or both, with each version laid out for its own frame rather than cropped. A Change it option lets a finished image be revised with a text instruction, and every version is kept under My thumbnails. The library is a notable extra. It holds thousands of thumbnails from popular channels, each carrying an outlier score that shows how far the video beat its channel's usual views. Results can be searched and filtered by tone, topic, style, mood, object or color, and a Recreate button turns any entry into a brief. Browsing requires signing in. Pricing is credit based: each finished thumbnail or revision uses one credit, and new users receive two free credits without a card. That makes WThumb a fit for solo creators, small channels and editors who want a quick path from a proven design to a custom one without design skills. Compared with general image generators or template editors such as Canva, it is narrower in scope but more directed, since the reference-first approach and outlier data are aimed squarely at click-through performance rather than open-ended art.
