Video Thumbnail Maker

By hijacker05

Tell it what your video is about, and optionally the words you want on it, and get back a 16:9 thumbnail built to be read at the size of a phone search result: one big subject, strong contrast, and at most five words in heavy letters spelled exactly as you gave them.

About this skill

Most thumbnails are seen at the size of a thumbnail, next to twenty others. This listing composes for that size first: one subject you can recognise at a glance, contrast strong enough to survive a small phone screen, and words big enough to read without zooming.

Text is optional. If you put a short headline in quotes, it is drawn in large, heavy letters exactly as you wrote it. Keep it to five words or fewer; the model spells short phrases reliably and long ones less so. Without a headline, the image has no text, and you can add your own in any editor.

The output is 16:9, the shape video platforms show thumbnails in. Check any text before you upload, and do not use it to imitate another creator's channel or a real person.

What comes back

  • One 16:9 thumbnail at 1K, the shape video platforms use.
  • One dominant subject with strong contrast, composed to read at phone-result size.
  • Your headline, if you give one, in at most five large words, spelled as written.
  • No small text, borders, logos or platform icons.

What it needs from you

  • What the video is about and the feeling it should give: surprise, curiosity, calm, urgency.
  • Optional: a headline of five words or fewer, written in quotes exactly as it should appear.
