If you need smaller files without severe artifacts:
| Format | When to Use | |--------|--------------| | WebP | Up to 30% smaller than JPG at same visual quality. | | AVIF | Superior compression for photos, but less browser support. | | JPEG Quality 60 | A better trade-off: still small but artifacts less noticeable. | | Resizing first | Reduce dimensions (e.g., from 4000px to 1200px) then save at Q80. |
