Pros: Small file size, excellent compression, widely supported

Cons: Lossy compression, no transparency support

PNG (Portable Network Graphics)

Best for: Graphics with transparency, simple images, screenshots

Pros: Lossless compression, transparency support, good for graphics

Cons: Larger file sizes, not ideal for photos

WebP (Web Picture Format)

Best for: Modern web applications, when file size matters

Pros: Excellent compression, supports both lossy and lossless, transparency support

Cons: Limited browser support (though improving)

Choosing the Right Format

• Use JPEG for photographs and complex images
• Use PNG for graphics, logos, and images requiring transparency
• Use WebP for modern web applications when supported
• Consider using multiple formats with fallbacks
