Tips & Best Practices
Thumbnail Design Tips
Keep important text and faces in the center of the image. YouTube may crop thumbnails on different devices. Use bold, contrasting colors and large, readable fonts. Test your thumbnail at small sizes to ensure it's still effective.
File Size Optimization
Our tool automatically compresses to under 2MB. For best results, start with high-quality source images. The compression algorithm maintains visual quality while reducing file size efficiently.
Aspect Ratio
Always use 16:9 aspect ratio (1280×720). If your image is a different ratio, our tool will resize it while maintaining the center focus. For best results, design thumbnails in 16:9 from the start.
Common Mistakes
- Don't upload thumbnails larger than 2MB - YouTube will reject them
- Avoid extreme aspect ratios - stick to 16:9 for best display
- Don't use low-resolution images - they'll appear pixelated at 1280×720
- Avoid placing critical text near edges - it may be cropped on mobile
