Frequently Asked Questions
What makes a good YouTube thumbnail?
Great thumbnails combine an expressive face, bold contrasting text (2-5 words), vibrant colors, and a clear focal point. They should be instantly readable at mobile sizes (320px wide) and create curiosity.
How does the thumbnail analyzer work?
Upload your thumbnail image (JPG, PNG, or WebP, max 4MB). Our AI vision model analyzes composition, text readability, facial expressions, color usage, and overall click appeal, then scores it 0-100 with specific fixes.
Is the thumbnail analyzer free?
Yes, completely free with no account required. Upload your thumbnail and get AI analysis in seconds.
What size should my thumbnail be?
YouTube recommends 1280x720 pixels (16:9 ratio). However, most viewers see thumbnails at 320x180 or smaller on mobile. Our analyzer evaluates readability at both sizes.
How important are thumbnails for views?
Extremely important. YouTube data shows that 90% of top-performing videos have custom thumbnails. A/B testing by creators consistently shows 20-50% CTR improvements from better thumbnails. They're often more important than the title.
