AI YouTube thumbnail maker for long-form video

Make the thumbnail your title deserves

Start from a topic, a working title, an exported key frame, a portrait, a product photo, or your channel look, and get a 16:9 thumbnail with one clear hero subject, readable hierarchy, and space left for the headline.

One clear hero subject · Headline-safe space · Readable at small size

One video, one cover that carries the title

Three directions, then one render

Compare three distinct approaches in words — subject, contrast, text area, background — and render only the one you pick.

Built for the small size

One hero subject with real separation from the background, so the image still reads when it is a card on a phone.

A look you can repeat

Leave with a channel rule, so the next thumbnail is recognizably from the same channel without starting over.

Thumbnails for explainers, reviews, tutorials, and series

Explainers and essays

Give a long-form idea a single visual anchor that matches the title's promise instead of restating it.

Reviews and comparisons

Put the product where the eye lands first and keep the comparison legible at card size.

Tutorials and how-to

Show the result or the moment of difficulty, with clear space for the step count or the outcome.

Gaming and vlogs

Keep the face and the scene readable together, with the expression carrying the hook.

Podcasts and series

Hold one layout across episodes so the series is recognizable in a subscription feed.

Start with the title

Bring the topic, the title, and an image if you have one

Share the promise the video makes, who it is for, and the subject that has to survive into the thumbnail.

  • Topic and working title
  • Exported key frame, portrait, or product photo
  • Channel look and destination
  • Must-keep subject and words to avoid

Compare before rendering

Three design directions, one recommendation

Each direction names its focal subject, contrast approach, text area, relationship to the title, and background treatment.

  • Three distinct visual directions
  • One recommended route
  • Title-matching notes
  • A safe text hierarchy

Then make it

16:9, one hero subject, headline space kept clear

The selected direction is rendered at 16:9 from your frame or as an original concept, and handed back with its actual dimensions and format.

  • 16:9 thumbnail at its actual output size
  • Faces, products, and logos treated as must-keeps
  • Headline area kept clear
  • A channel rule for the next one

Questions

Can I start from just a title?
Yes. A title and the promise behind it are enough to shape directions; a key frame or portrait gives the hero subject something real to build on.
Can you use a frame from my video?
Export the frame or take a screenshot and share it, and it becomes the hero subject the thumbnail is built around.
Can I put text in the image?
Yes. Give the exact wording and where it should sit, and it is set before rendering so the layout is built around it. Image models do not always draw letters exactly, and changing a word means rendering the thumbnail again, so you can also keep the text out of the image: leave a clear headline area and set the title yourself afterwards.
Can I keep one look across a series?
Yes. An accepted direction becomes a channel rule covering subject placement, contrast, and text area, so later episodes match.

Bring the frame, leave with the thumbnail

Share the title, the promise, and a key frame or portrait, and get a 16:9 thumbnail built around one hero subject with room for the headline.
