JPG to WebP Converter

If you're optimizing a site for Core Web Vitals, converting JPEGs to WebP is one of the highest-impact wins available: WebP files are typically 25–35% smaller at equivalent quality, which directly improves LCP and page load times. Drop a JPG above, tune the quality slider, and grab a lighter file.

Everything happens in your browser via WebAssembly — no upload queues, no privacy concerns, no watermarks.

FAQ

How much smaller will my JPG get?

Most photographic JPEGs shrink by 25–35% at the default quality. Flat graphics and screenshots often compress even further.

Should I convert all images on my site to WebP?

Almost certainly yes — WebP is supported by every modern browser (97%+ global coverage). Keep JPEG fallbacks only if you target very old clients.

Are my photos uploaded?

No. Conversion is 100% client-side; your photos never leave your device.
