Compressing WebP to Under 100 KB
100 KB is the recommended default web target for WebP. At around Q78 it matches the quality of a 130–150 KB JPEG, freeing bandwidth for faster pages. Use it for product images, article photos, and graphics with transparency. Dimensions stay up to about 1920 px. This is the target most sites should standardize on for above-the-fold and content imagery, since it offers the best size-to-quality ratio of any widely supported format.

Frequently Asked Questions
How much smaller is WebP than JPEG at the same quality?
Typically 25–35% smaller at equivalent perceived quality. At 100 KB you get quality comparable to a noticeably larger JPEG.
Should I convert old PNGs and JPEGs to WebP?
For web delivery, yes — you keep the same visual quality and transparency while shrinking files, which improves load time and Core Web Vitals.
