About Thumbrix

Thumbrix helps video creators turn an idea into a thumbnail without starting from a blank design canvas. Describe your video, optionally add a photo and a short headline, and review the result on the same page.

What you can create

The generator creates a single 16:9 image per request. It supports text descriptions and a JPG or PNG reference photo. The examples on our homepage illustrate possible directions; they are not live results or a promise of identical output.

Free and paid use

New accounts get 20 free credits, shared across image tools. One-time credit packs start at $2.99 for 60 Credits; monthly plans add 2K/4K generation. Images use credits by size and model, shown before you generate. See the current pricing before purchasing.

Review before publishing

AI can change facial details, objects and lettering. Check the image, spelling and final crop before using it. A thumbnail should accurately represent the video it accompanies. Thumbrix does not guarantee clicks, audience growth or a particular visual result.
