JPEG: Ideal for photographs

JPEG uses lossy compression. Ideal for photographs and images with gradients. Does not support transparency.

Advantages: Small file size, universal browser support, adjustable quality (1-100). Disadvantages: No transparency, text and lines may blur, quality loss on every save.

Use cases: Photographs, banner images, website hero images, email attachments.

PNG: Transparency and sharp edges

PNG uses lossless compression. Supports transparency (alpha channel). Ideal for text, logos, and line art.

Advantages: Transparency support, sharp edges, lossless quality, animation (APNG). Disadvantages: Large file size for photographs, 2-5x larger than JPEG.

Use cases: Logos, icons, screenshots, images requiring transparent backgrounds, line art.

WebP: Modern and efficient

WebP is a modern format developed by Google. Supports both lossy and lossless compression. Provides 25-35% smaller file size compared to JPEG and PNG.

Advantages: Small file size, transparency support, animation, both lossy and lossless. Disadvantages: Not supported in older browsers (IE11 and earlier).

Use cases: Website images, any image type if targeting modern browsers.
