Thumbnail tester, rater, checker & viewer — FAQ
How do I test a YouTube thumbnail for free?
Paste the video link above. The page loads that video's real thumbnail and puts it side by side with proven examples so you can compare and vote. No sign-up required.
What is the difference between a thumbnail tester, rater, checker and viewer?
They are the same job described with different words. A tester previews your thumbnail, a rater gives it a score, a checker compares it with others, and a viewer shows it at real size. This page covers all four in one place.
Is my thumbnail score official or from YouTube?
No. The percentage here is based only on the votes made in your own browser. It is a quick gut-check, not YouTube's real click-through data. YouTube does not publish per-thumbnail CTR.
Do you store my video or images?
No. The thumbnail is loaded from YouTube's public image server, and votes are stored only in your browser. There is no upload and no account.
