Stop the Scroll. AI Generator for High-CTR Video Ad Thumbnails.
Don't let a bad cover kill your video ad's performance. Lovart's AI Design Agent helps you create scroll-stopping thumbnails for TikTok, YouTube, Instagram, and Facebook. Upscale blurry frames, A/B test text hooks instantly, and design covers that demand clicks.
Create Winning Thumbnails in 3 Steps
Start with a Frame
Upload a screenshot from your video or describe the scene. Lovart's 'Upscale' will instantly turn a blurry frame into a crisp 4K image ready for editing.
Hook Them Instantly
Use 'Text Edit' to add or change bold headlines directly on the image. Test 'Review', 'Warning', or 'Offer' hooks in seconds without Photoshop.
Adapt to Any Feed
Need a 9:16 for TikTok and a 16:9 for YouTube? Use 'Expand' to intelligently extend your background, ensuring your thumbnail fits every platform perfectly.
The Ad Creative Toolkit
Text Edit for A/B Testing
The ultimate hook tester. Change the text on your thumbnail instantly to see which headline drives more clicks. AI matches the font and style automatically.
Upscale to 4K
Video screenshots are often low-quality. Our AI Upscaler enhances details and resolution, making your static cover look professional and sharp on all devices.
Edit Elements
Fix the composition. Move the subject to the side to make room for text overlay, or resize product elements to make them pop, all within the canvas.
Expand / Resize
One design, all platforms. Use AI Outpainting to extend your 1:1 image into a 9:16 Story format or a 16:9 Banner without cropping out key details.
Remove Background
Isolate your subject instantly. Place your product or spokesperson onto a high-contrast or branded background to make them stand out in a busy feed.
Style Transfer
Match the vibe. Apply a 'Cyberpunk', 'Minimalist', or 'Paper Cutout' style to your thumbnail to differentiate your ads from competitors.
