FAQ

Thumbnail Generator FAQ

What is a thumbnail generator?

A thumbnail generator creates video thumbnail images using AI. Describe what you want in plain language, and it generates complete images in about thirty seconds. Then add text overlays and export for YouTube.

How do I generate thumbnails for YouTube?

Type a description of what your video is about. The AI generates thumbnail options, you pick your favorite, add title text with the editor, and export in HD. Upload the file to YouTube Studio when publishing.

Are AI-generated thumbnails allowed on YouTube?

Yes. YouTube allows AI-generated thumbnail images as long as they accurately represent your video content and follow community guidelines. The creation method doesn't affect eligibility.

What makes a good video thumbnail?

High contrast colors, readable text under 5 words, expressive faces when relevant, one clear main subject, and mobile-optimized design. Test at small sizes to verify readability.

Can I edit thumbnails after generating them?

Yes. Every generated image opens in the editor where you can add text, adjust colors, remove backgrounds, or refine details. Most creators generate the base image then spend a minute or two adding final touches.
