PNG vs JPEG vs WebP — Which Should You Use?
| Format | Compression | File Size | Best For |
|---|---|---|---|
| PNG | Lossless | Larger | Screenshots, logos, images with transparency, graphics with sharp edges |
| JPEG | Lossy | Small | Photos, images for email, social media, web pages — where file size matters |
| WebP | Best compression | Smallest | Web images — 25–35% smaller than JPEG with better quality, supported by all modern browsers |
