WebP
WebP placeholders for modern image pipelines
WebP is standard in many frontends — but a quick dummy asset is often missing. Create WebP placeholders at the size you need and embed them by URL.
Test performance realistically
WebP placeholders let you exercise lazy loading, srcset, and cache headers without heavy photos. The image URL service serves the format directly.
Fallback strategies
Generate JPG/PNG alongside WebP to verify picture elements and Accept-header logic. The format converter helps you switch quickly.
AVIF next door
Taking the next step: the same generator also supports AVIF — useful for A/B and codec comparisons.
