WebP was developed by Google specifically to replace JPEG and PNG on the web, and it typically produces files 25 to 35 percent smaller than a comparable JPEG at similar visual quality, while also supporting transparency, which JPEG cannot do at all. Because WebP supports both lossy and lossless compression modes in the same format, it can serve as a replacement for both JPEG-style photos and PNG-style graphics depending on which mode is used.
WebP has broad support across all current major browsers, which is why it's become a popular target format for website images where faster page loads directly affect user experience and search ranking. The main thing to verify is whether any older software or specific platform you're working with has full WebP support, since adoption, while now widespread, wasn't always universal.
