AI YouTube Thumbnail Generator

Generates a 16:9 thumbnail from a description, or better, from a real frame of your video. Text is left off on purpose, because image models render lettering badly.

Input

A thumbnail made from a text prompt alone rarely looks like your actual video. MrBeast's team built an AI thumbnail tool and dropped it for this reason. Paste a link to a real frame from your video below and describe what to change, and this tool edits that frame instead of inventing a new scene.

What this does

Describe the thumbnail, or better, paste a link to a real frame from your video and describe what to change. With a reference frame this edits that photo. On its own it invents a scene from your words, which rarely ends up looking like you or your set.

The image never carries any text. Models render lettering badly, so we leave the space clean and you add the title afterwards with a text tool. MrBeast's team built an in-house AI thumbnail tool and shut it down over quality, so treat a pure text prompt here as a rough draft, not a finished thumbnail.

Use cases
  1. 01Sketch a thumbnail concept before you sit down in an editor.
  2. 02Edit a real frame from your video into a punchier crop instead of starting from nothing.
  3. 03Test a scene idea before you light and shoot it for real.
Glossary
FAQ

Questions, answered.

Will this look like an actual photo of me?

Not from a text prompt alone. Paste a link to a real frame from your video and describe the change, and the tool edits that photo instead of inventing a new face.

Why is there no text on the thumbnail?

Image models render letters badly, so we leave the space clean and blank. Add your title afterwards with a text tool, the way most thumbnail workflows already work.

Do I need an account?

Yes. AI Thumbnail Generator is a Pro tool, 20 credits a run.
