PageSpeed precision ladder

Omega can generate a dense responsive candidate ladder so browsers can choose an image much closer to the actual rendered requirement. Candidates above the source width can be skipped when no-upscaling is enabled.

Browser-facing responsive delivery is normally best suited to modern web formats such as AVIF/WebP with an appropriate fallback; other formats remain available for output/download workflows.
Purpose-specific sizing
Responsive images and website icons use different size logic.
Normal web imagery follows the selected responsive width ladder without unnecessary upscaling. Favicon and ICO modes ignore that ladder and automatically use their correct fixed icon sizes, keeping the output appropriate to its intended use.
