Which Image Format Should You Use?
Format | Best for | Notes |
|---|---|---|
JPG / JPEG | Photos, web images | Smaller file size, some quality loss |
PNG | Logos, screenshots, transparency | Lossless, larger file size |
WEBP | Websites, faster page loads | Smaller than JPG/PNG at similar quality |
JFIF | Older devices, legacy web images | Functionally identical to JPEG |
