WebP encodes the same photo about 25–35% smaller than JPEG at equal visual quality, which is why page-speed tools recommend it. The converter decodes your JPG in the browser and encodes WebP at quality 92; the result looks identical and loads faster.
Every current browser displays WebP, and it has been safe to serve without a JPEG fallback since Safari 14 in 2020.
WebP is a display format. If the image is going to a print shop, into a Word document or to someone using older desktop software, keep the JPG. Converting JPG to WebP also does not recover quality: it is lossy-to-lossy, so do it once from the best source you have rather than repeatedly.
