YouTube thumbnail compare
Compare two YouTube thumbnails side by side
Two options, one screen. Paste two URLs and see which still reads at a glance — before you swap the custom thumbnail in Studio.
How to A/B two YouTube thumbnails
- Keep option A live in Studio (or unlisted).
- Upload option B to a second unlisted video, or keep a draft ID you already published.
- Paste both links here. Look at faces, contrast, and type size — not just which JPEG you “like.”

https://www.youtube.com/watch?v=VIDEO_ID_BYouTube’s official thumbnail test (when available on your account) measures clicks. This compare tool does not. It stops you from shipping a still that loses the face at phone size. After you pick a winner, download it from the HD downloader or check overlays in the safe-zone preview.
What to look for in a thumbnail comparison
- Face size — the winner is usually the bigger, clearer face at 120 pixels wide.
- Contrast — a busy background loses to a simple one in search.
- Type — three words beat a paragraph. If both have type, the one that survives the title overlay wins.
- Honesty — a still that does not match the video trains people to skip next time.
Compare vs bulk vs one video
Two URLs: this page. Fifteen URLs into a ZIP: bulk downloader. Every quality of one ID: homepage. Same job, different width.
FAQ
YouTube thumbnail compare FAQ
How do I compare two YouTube thumbnails?
Paste two video URLs (or IDs) into this compare tool. You get both stills side by side with titles when oEmbed knows them. Use it for A/B before you change Studio.
Can I compare a Shorts thumbnail to a long-form thumbnail?
Yes. Mix a Shorts URL and a watch URL. Both resolve to the same kind of CDN still; the crop on the player is what differs.
Does this download both thumbnails?
You can download each still from the result. Compare itself is a preview so you do not have to open two tabs.
What if one video has no maxresdefault?
That side shows the next real size. The missing HD file is not faked. Use the size checker if you need the pixel numbers.
Is this a YouTube thumbnail A/B test?
It is a visual A/B on your desk. YouTube’s own test in Studio is a different product. This page does not change CTR; it helps you pick before you upload.
Can I compare more than two thumbnails?
This page is two at a time so the grid stays readable. For a series, use the bulk downloader and open the ZIP.
