WThumb
WThumb creates YouTube and Shorts thumbnail designs from a link, image or written brief, with optional face references and revisions requested in plain language.
About this tool
WThumb generates thumbnail artwork from a written video brief or a visual reference. Users can provide a YouTube link whose thumbnail conveys a desired direction, upload an image or work from words alone. The purpose is to develop a new design around the brief rather than extract a frame from an uploaded video.
The workflow supports designs with a face reference or a faceless composition. Horizontal YouTube and vertical Shorts versions are described, along with revisions requested in ordinary language. Each resulting image still needs a review for legible text, faithful likenesses and an honest relationship to the actual video.
What you can do
Reference and prompt inputs
A thumbnail link, uploaded image or text description can guide layout and emphasis. Describe what should change so a reference informs the design without becoming a copied asset.
Face or faceless designs
Users can supply a persona reference or omit a face. Use photographs with permission and inspect the generated likeness before associating it with a person.
Language-based revisions
Changes are requested through a written instruction rather than a layered canvas. Versions remain available in a gallery, with revisions consuming credits under the described arrangement.
Who is it for?
- Draft a thumbnail for an educational video using a title and a description of the main concept.
- Compare horizontal and vertical treatments of the same video idea for YouTube and Shorts.
- Request a clearer headline or different composition after reviewing the first generated design.
Before you choose
Confirm current credit charges, revision costs and output dimensions before creating a large batch.
Review reference-image rights and avoid misleading imagery or claims that the video does not support.
Frequently asked questions
Do I need to upload my video file?
The described inputs are a YouTube link, an image or a written brief. Video-file analysis and automatic key-frame selection are not established by that workflow.
Can I create a design without showing my face?
Yes. A faceless option is described, and a design can begin from words alone. Review whether the composition still communicates the video clearly at a small display size.
Does WThumb change the thumbnail on my YouTube account?
The described result is a downloadable JPEG design. A file intended for YouTube does not establish direct account publishing; plan to review and apply the image through the appropriate channel controls.
