How to convert JPG to WebP

For best results keep the quality at high for rich photos, or lower it slightly if you actively want an even smaller file.
Is it lossless-looking?
At high quality settings, WebP is visually indistinguishable from the source JPG. The savings come from a smarter compression algorithm, not from reducing pixels.
Why WebP is the default web format now
WebP typically produces files 25-35% smaller than JPG at the same visual quality, which is the entire reason every major site serves it: faster first paint, less bandwidth on mobile, lower CDN bills. It also carries transparency and animation, which JPG cannot do at all, so a single format can replace both JPG and GIF in modern pipelines.
Browser support is no longer a question - every browser in use since 2020 renders WebP natively. The one genuine caveat is downstream tooling: some email clients, older desktop software and a few upload portals still reject the extension, and a converter round-trip (JPG to WebP and back) doubles the lossy generations. The safe pattern is to keep the original JPG as master, generate WebP derivatives for the site, and fall back to the JPG when a tool says no.
