- **Compression**: Lossy algorithm - **Best for**: Photographs and complex images - **File size**: 50-200KB (compressed) - **Quality**: 80-90% recommended - **Everywhere**: Universally supported
PNG Format
- **Compression**: Lossless algorithm - **Best for**: Graphics, logos, screenshots - **Transparency**: Full support - **File size**: Larger than JPEG - **Quality**: Perfect preservation
WebP Format
- **Compression**: 25-35% smaller than JPEG - **Modern**: Google's new format - **Transparency**: Full support with animation - **Browser support**: ~95% (except old IE) - **Best for**: Web images, e-commerce
