AI 縮圖產生器

Need a YouTube thumbnail without opening an image editor?

為您的影片或直播產生吸睛的 AI 縮圖 — 輸入標題，取得設計來吸引目光的封面圖。

Your thumbnail sits right next to your title in every feed, and a short, readable headline with a clear composition helps a video stand out. Enter a main headline of up to 120 characters, plus optional supporting text, and the generator builds a widescreen 16:9 thumbnail around it. Keep the headline to a few strong words; thumbnails are often seen at small sizes, and short text stays readable.

Choose from four styles: Vibrant, Cinematic, Minimal or Reaction. The result works as a YouTube video thumbnail or a Twitch stream cover. If the first image isn't quite right, tweak the wording or switch styles and generate again. Each attempt is a fresh image, so small wording changes can give quite different layouts.

You need to be signed in, and each image costs 150 coins, shown before you generate. If generation fails, the coins are refunded automatically. Finished thumbnails download straight away as PNG or JPG files. The tool works from text only; uploading your own photo into the design isn't supported.
