Frequently Asked Questions

How does the YouTube thumbnail checker work?

You upload your thumbnail image and enter your planned title. Our AI analyzes the visual impact, text readability, emotional appeal, and title strength — then returns a score out of 100 along with actionable recommendations.

Is ThumbnailScore free to use?

Yes — you get 3 free analyses per day with no account required. Create a free account to raise that limit and unlock history tracking.

What makes a good YouTube thumbnail?

High-CTR thumbnails share four traits: a single clear focal point, bold contrasting colors, minimal readable text (under 5 words), and an emotional face or striking visual element that creates curiosity.

Does ThumbnailScore store my image?

Only if you are signed in. Your thumbnail is sent to our AI for analysis; signed out, nothing is kept. When signed in, a small preview image (about 200 px wide), your score, and your title are saved to your private history and deleted after 30 days.
