How is Thumbfa.st different from a generic image generator?

It is built specifically for YouTube thumbnails rather than being a general image generator. It focuses on face consistency, copying proven thumbnail styles, up to four variants per generation and correct 1280x720 output.

How does the face consistency work?

You upload your photos and a description once to create a Person profile. Every future generation can then reference that profile so your likeness stays recognizable.

Is there a free plan?

You can start free with five thumbnails included, up to two thumbnails at a time, ten inspirations and two person profiles, but exports carry a watermark on the free plan.

Can I copy the style of a thumbnail I like?

Paste a YouTube URL and Thumbfa.st extracts the thumbnail and analyzes its style, colors, text placement and composition, saving it to your inspiration library to reference later.

Can I generate multiple variations for A/B testing?

Yes, you can generate up to four variations at once, which is designed to support A/B testing against rival thumbnails.

What resolution are the thumbnails?

Thumbnails are produced at 1280x720, YouTube's recommended resolution, and downloaded as high-quality PNG files ready for YouTube Studio.
