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.
