PNG (Portable Network Graphics): A lossless image format that supports transparency. PNG files are larger than JPEG but preserve perfect quality. Ideal for logos, graphics with text, screenshots, and images requiring transparency. File extension: .png

WebP: A modern image format developed by Google that provides superior compression. WebP images are 25-35% smaller than JPEG while maintaining similar quality. Supports both lossy and lossless compression, plus transparency. Perfect for modern websites and web applications. File extension: .webp

GIF (Graphics Interchange Format): Supports animation and transparency. Limited to 256 colors, making it unsuitable for photographs but perfect for simple animations, icons, and graphics. File extension: .gif
