About YouTube Thumbnail Maker
A thumbnail is judged at thumbnail size on a phone, which makes the rules concrete: few words, high contrast, and keep the bottom-right clear for the duration badge. Those constraints are baked into the defaults here — you supply the image and the headline.
Photo editing steps
Prepare your input, choose the edit and review the output before using it:
- Upload a face or source image
- Pick a style
- 16:9 composition
- Raise contrast and saturation
- Avoid the duration badge area
- Export 1280×720

Frequently Asked Questions
Why was my headline cut off?+
It is too long or too close to the edge. Shorten it and keep it in the central safe area.
Is there a file size limit?+
YouTube caps thumbnails at 2MB; the JPG export is optimised for that.
Image handling and privacy
This is an AI tool: images you upload are sent to the configured inference service for processing, not handled locally in the browser. The active route is managed internally and is separate from the model developer. You can delete any generation from your history at any time.
