PNG is lossless, so files tend to be large. Converting to WebP typically shrinks them by roughly 25 to 35 percent with little visible quality loss, and often even more for images with flat colors or large transparent areas. The exact saving depends on the image content, but for most photos and graphics WebP is a clear win for web performance.
