Free tool

YouTube thumbnail analyzer Score your thumbnail and see what people notice first.

Drop a thumbnail and get a score out of 100 in a second: what gets seen first, whether the face or the title wins, and what pulls the eye away. Score two versions, upload the winner. Free, no sign-up.

Why people pick this one

A preview tool shows how your thumbnail looks in the feed. This one shows what a viewer's eye does with it: where it lands first, what it skips, and how much of the glance your title gets.

JPG, PNG and WebP thumbnails, covers, banners and ad images, any size.
Comes back as
A score out of 100, three readings (First glance, Focus, Clarity), the three spots seen first, a heat view over the thumbnail, tips, and a report card.
Detail
Draw a box over the face, the title or the logo and see its exact share of attention.
Limits
None. Score as many thumbnails as you like.
Price
Free, no sign-up.

How to test a thumbnail in three steps

  1. Drop the thumbnail in. The score and the heat view appear in a second.
  2. See what wins the glance. The spots people notice first are numbered. Drag a box over your title and your face to see which one gets more.
  3. Fix and score again. Bigger face, bolder text, plainer background: drop the new version in and keep the higher score.

Questions people ask

What makes a thumbnail score high?

One clear thing to look at, seen at first glance, with nothing fighting it. A big face or a bold word on a plain background usually scores higher than a busy scene.

Can I compare two thumbnails?

Yes. Score one, download its report, then drop the second in. Upload the one with the higher score, or the one where the title gets the bigger share.

Does it work for Shorts covers and Instagram posts?

Yes. Vertical and square images are scored the same way.

Is it free?

Yes, with no limit on the number of thumbnails and no sign-up.
