JPG to WebP Converter

Convert JPG to WebP for 25–35% smaller files. Browser-based — no upload, batch supported.

Why convert JPG to WebP?

WebP at the same visual quality as JPG produces files roughly 25–35% smaller — a meaningful win for page speed, hosting bandwidth, and mobile data. The conversion does involve re-encoding (lossy → lossy is never quality-perfect), so for archival use stick with the original JPG. For web delivery, WebP is the modern default. The libwebp encoder is processed in your browser via WebAssembly.

About JPG

JPG is the universal photo format — lossy, no transparency, broadly compatible.
  • JPEG standard published in 1992
  • Lossy compression — already discards detail; further conversion to WebP is double-lossy
  • WebP can preserve JPG quality at 25–35% smaller file size

Frequently asked questions

Will the WebP be visually identical to the JPG?
At quality 85+ the difference is imperceptible to the eye in side-by-side comparison. JPG → WebP is double-lossy though, so for archival or editing use, keep the original JPG.
