Miniatures YouTube
Générez des miniatures YouTube accrocheuses avec l'IA — des mises en page testées qui boostent le CTR.
Thumbnails Make or Break Your Videos
YouTube's own data shows that 90% of top-performing videos use custom thumbnails. Your thumbnail is the single biggest factor in whether someone clicks your video or scrolls past it. A great thumbnail can double or triple your click-through rate, directly impacting views, watch time, and channel growth.
AI-Generated Thumbnails That Get Clicks
DesignerBox generates YouTube thumbnails using proven design principles — bold text, expressive faces, contrasting colours, and clear visual hierarchy. The AI understands what makes thumbnails click-worthy and applies these principles to your specific content and niche.
Customise to Your Brand
Maintain a consistent thumbnail style across your channel while keeping each one unique. Set your brand colours, preferred fonts, and layout style, and DesignerBox generates thumbnails that are instantly recognisable as yours. Include faces, products, text overlays, backgrounds, and effects — all controlled through simple prompts.
Test Multiple Options Instantly
Don't guess which thumbnail will perform best — test them. Generate multiple thumbnail variations for each video in seconds, then use YouTube's built-in A/B testing or your analytics to find the winner. The speed of AI generation means you can iterate on thumbnails even after publishing.
