Make a YouTube Thumbnail from a Photo with AI

    A 3-step workflow that turns a portrait or product photo into a click-ready YouTube thumbnail.

    YouTube thumbnails are 1280×720 — wider than most phone photos. This workflow gets you there cleanly: Background Remover isolates the subject so you can re-place them, Image Extender outpaints the photo to the correct 16:9 aspect ratio without crop or stretch, and Image Editor adds the bold text overlay that drives click-through. Built for creators who do not want to learn Photoshop just to ship a thumbnail.

    Frequently Asked Questions

    What size thumbnail should I export?

    YouTube requires 1280×720 minimum, under 2 MB, as JPG or PNG. The Image Editor exports at this size by default.

    Can I do this on mobile?

    Yes — every tool runs in the browser, including on iOS and Android.

    Will the extended background look fake?

    For simple scenes (sky, walls, plain surfaces) the outpainting is usually invisible. Busy scenes may need a manual touch-up.
