Why convert JPG to WebP?

JPG is the universal photo format, but it carries 25-year-old compression baggage. WebP gets the same image quality in 25–35 % fewer bytes, which directly helps Lighthouse / Core Web Vitals scores, mobile data plans, and CDN bills. Every modern browser renders WebP natively, so for anything web-bound the conversion is essentially free.

Stick with JPG when you're emailing a photo to someone on a ten-year-old mail client, uploading to a CMS that hasn't updated since 2018, or attaching to a Word doc you don't control. For everything else — site assets, social posts, product photos — WebP is the smaller, faster choice.
