What is a JPG file?

JPG (or JPEG) is the most common format for photos. It uses lossy compression, discarding detail the eye barely notices, so photos become small files that open in every app, browser and phone. It has no transparency, and repeated editing and re-saving gradually lowers quality, so it suits finished photos rather than graphics with sharp text.

What is a WebP file?

WebP is a modern image format developed by Google for the web. It supports both lossy and lossless compression as well as transparency, and its files are usually noticeably smaller than JPG or PNG at similar quality. All current browsers display WebP, but some older desktop apps and upload forms still don't accept it.
