Why convert JPG photos to WebP
WebP was designed for the web. At the same visual quality a lossy WebP is usually 25–35% smaller than a JPG, which directly speeds up the pages it sits on. Every current browser displays it, and most CMSs and site builders accept it.
Because both formats are lossy, converting re-encodes the picture, and each lossy save costs a little detail. Start from the original JPG, not one that's already been compressed and re-saved, and keep the quality around 80–90.
WebP is a web format first. Some older desktop software, printing services and upload forms still reject it, so keep the JPG for anything that isn't going on a website.

Converting formats, answered
Is WebP better than JPG?
For websites, yes: smaller files at the same quality, with transparency and animation support JPG lacks. For sharing with people or printing, JPG is still the safer choice because everything opens it.
Does converting JPG to WebP lose quality?
Slightly, since the image is decoded and compressed again. At quality 80–90 the difference isn't visible; start from the best original you have.
Can everyone open a WebP?
All modern browsers can, and so can current versions of Windows, macOS, Android and iOS. Some older editors and upload forms can't, which is why it's best kept for the web.
Are my images uploaded?
No. The conversion runs in your browser, so the files never leave your device and it keeps working with your connection off.
