01 — Why this tool?

Convert JPG to WebP…

Since Google's Page Experience update, loading speed has become an official ranking factor. The Core Web Vitals — LCP, INP, and CLS — measure how fast and stable your site feels, and the LCP (Largest Contentful Paint) is almost always driven by your main image. That's exactly where WebP shines: it delivers JPG-equivalent visual quality at one-third less file size, which can push an LCP from 3.5 seconds down to under 2 seconds without touching anything else in your code. WebP is also natively supported by every modern browser — Chrome, Edge, Firefox, Safari (since macOS 11 / iOS 14), and Opera — meaning over 97% of global users. Converting your JPG catalog to WebP is probably the highest-ROI SEO quick-win you can run in a few minutes: less CDN bandwidth consumed, better Google rankings, and a meaningfully smoother experience on mobile 4G or low-bandwidth connections.
