WThumb

Overview

WThumb (Winning Thumbnail) is a web-based AI tool for creating YouTube thumbnails. It helps video creators generate thumbnails for long-form videos (16:9) and Shorts (9:16) without using traditional image editors. ### Core Workflow Users can start the generation process in three ways: - **Paste a YouTube link**: Enter a video link you like. WThumb reads its layout, hierarchy, and visual style, then recreates it around your title. - **Upload an image**: Upload any image as a reference, or add extra assets such as products or logos. - **Text description**: If you have no reference image, simply enter your video title and content description, and let the AI design from scratch. The entire interaction takes place in WThumb Studio through a short conversation. You confirm the format, whether to include a face, the exact copy, and any details to adjust, then click Make to generate. Each generation or edit costs 1 credit. ### Key Capabilities - **Face and Faceless modes**: Save a Persona (name and photo) so the AI blends your face into the thumbnail, or choose Faceless mode— even if the reference contains people, the result will be rebuilt without them. - **Natural language edits**: Click the pencil icon on a generated thumbnail and describe your changes in natural language to get a new version. All previous versions are kept in your gallery. - **High-resolution output**: 16:9 thumbnails export as 2048 × 1152 JPEGs and 9:16 as 1152 × 2048, watermark-free and ready to upload to YouTube. - **Landscape/portrait conversion**: Redesign landscape references into portrait thumbnails and vice versa, rather than simply cropping. - **Multilingual support**: Copy can be entered in any language. ### Thumbnail Inspiration Library WThumb includes a built-in Library of thousands of thumbnails from popular channels. Each thumbnail shows an Outlier score—the multiple by which the video's views exceeded the channel's average. Filter and search by tone, topic, style, mood, object, or color, then jump straight into the recreation workflow with one click. ### Who It's For WThumb is ideal for solo creators, podcasters, and gaming channel operators who lack design skills but need to update their YouTube thumbnails frequently.

Q&A

How does WThumb work?AI-generated

Open Studio and paste a YouTube link, upload an image, or describe your video in text. A short conversation walks you through the format, whether to include a face, the copy, and any edits. Confirm and click Make to generate. Only then do you need to sign in with Google or email.

Do I have to put my own face on the thumbnail?AI-generated

No. Skip the photo upload and choose Faceless mode. Even if the reference image contains people, WThumb rebuilds the layout without them.

What resolution are the generated thumbnails?AI-generated

16:9 thumbnails are 2048 × 1152 JPEGs and 9:16 thumbnails are 1152 × 2048—both above 1080p, watermark-free, and ready for YouTube uploads.

Can I edit a thumbnail after it's generated?AI-generated

Yes. Click the pencil icon on a finished thumbnail and describe your changes in natural language; WThumb generates a new version. Each edit costs 1 credit, and all versions are saved in your gallery. Canvas- or layer-style editing is not supported.

How is WThumb priced?AI-generated

Verify your account to get 2 free credits—no credit card required. Paid plans start at $12/month ($9/month billed yearly) across Starter, Creator, and Studio tiers. All plans use the same generator and image quality.

Which languages are supported? Can others see my thumbnails?AI-generated

Copy can be entered in any language. Generated thumbnails and uploaded assets are visible only to your account and remain private.

Can I turn a landscape reference into a portrait thumbnail?AI-generated

Yes. Choose YouTube 16:9, Shorts 9:16, or both at the start, and WThumb redesigns the composition for the selected frame instead of simply cropping.

Can I use my own image as a reference?AI-generated

Yes. Besides pasting a link, you can upload any image as a reference and add extra assets like product photos or logos into the thumbnail.

What kind of photo works best for upload?AI-generated

A clear, well-lit face photo, ideally looking straight at the camera. Both studio shots and phone selfies work fine.

What does the name WThumb mean?AI-generated

WThumb stands for Winning Thumbnail—W for Winning and Thumb for Thumbnail.
