AI Thumbnail Maker

Describe the thumbnail - the expression, the object in frame, the background, the colour that should dominate - and Zappy renders it. Generate a batch, then pick the one that stops the scroll.

Choose the wide 16:9 shape so the image is already the right proportion for YouTube, and use Ideogram 3 when the thumbnail needs readable words inside the picture.

How it works

1

Describe the shot

Say what is in frame and what the mood is. Bold, simple and high contrast beats detailed.

2

Set it to wide 16:9

Pick the wide aspect so the thumbnail is not cropped awkwardly when YouTube scales it.

3

Generate a few and choose

At 1 credit on the fast models you can make a dozen options and only keep the best one.

FAQ

Can it put text on the thumbnail?

Yes - use Ideogram 3, the model in the line-up built for rendering legible text inside an image. It costs 8 credits. You can also add a title afterwards in any editor.

What size are the thumbnails?

Pick the wide 16:9 shape and the output already matches what YouTube expects. Keep faces and text away from the very edges, since small players crop tightly.

Is it free?

The fast models cost 1 credit and you get 25 free credits a day. Ideogram 3, the one worth using when you need text, costs 8 credits per image.
