About the Thumbnail Maker

Thumbnail Maker builds a YouTube thumbnail from your own photo in three styles: a bold big-text look, a clean split layout, and a face-and-arrow layout. Type your video topic and Zyn suggests 3 short thumbnail texts with a highlight word and a colour scheme for each (these are AI suggestions; you can change everything). The image itself is drawn in your browser, so your photo is never uploaded to our server.

How it works

Add your photo, or skip it and use a colour background.
Type your video topic and tap "Get AI suggestions" for 3 text ideas.
Pick a style, edit the text, colours and photo position, then download a 1280×720 PNG or a JPG under 2 MB.

Free to use. AI text ideas count as 1 use each with a daily free limit; editing and downloading are unlimited.
