JPEG has been the web's standard photographic format since the 1990s, but WebP — developed by Google — achieves roughly 25-30% smaller files at equivalent visual quality. Converting JPEG to WebP is the single most impactful optimization for website performance, reducing image payload without visible quality loss. The .jpeg extension is identical to .jpg and produces the same WebP output.
WebP uses VP8 lossy compression for photographs and VP8L lossless compression for graphics, both more efficient than JPEG's 1992-era DCT algorithm. All modern browsers support WebP, making it a straightforward upgrade from JPEG for web delivery.
Smaller images mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores. Converting JPEG to WebP typically saves 25-30% in file size with no visible quality difference, directly improving Largest Contentful Paint (LCP) and overall page speed scores. This translates to better SEO rankings, lower bounce rates, and reduced hosting bandwidth costs.
WebP is now universally supported in modern browsers (Chrome, Firefox, Safari 14+, Edge). The format also supports alpha channel transparency and animation, features JPEG lacks entirely. For web publishers, JPEG to WebP conversion is the lowest-effort, highest-impact performance optimization available.
Sharp decodes the JPEG using libjpeg-turbo and re-encodes via Google's libwebp at configurable quality (1-100). VP8 lossy compression is used for photographic content, achieving 25-30% smaller files than JPEG at equivalent quality. Chroma subsampling matches the JPEG source. EXIF metadata can be preserved or stripped. ICC profiles are applied during conversion. The output supports progressive-style incremental rendering natively.
At WebP quality 80-85, the output is visually indistinguishable from the JPEG source for photographic content. WebP handles fine textures and gradients more gracefully than JPEG, with less blocking artifact visibility. The quality advantage increases at lower quality settings — WebP at quality 60 looks significantly better than JPEG at quality 60. For near-transparent conversion, use WebP quality matching the JPEG quality minus 5-10 points.
