Images (formats and weight)
Image optimization combines modern formats — AVIF, WebP — sizing to the exact pixel needed, and appropriate compression. First contributor to page weight, first source of speed gains.
In practice
The pipeline automates: multi-format conversion on import, variants by screen size, serving the negotiated best format. A 4 MB photo has no place in a 300-pixel thumbnail — the picture element and srcset attributes exist precisely for that. Our pipelines reject raw images at the gate; compliance is not optional.
