Why convert PNG to WEBP?

PNG is a lossless format, which makes it reliable for graphics and UI assets but also makes it much larger than necessary for the web. WEBP supports both lossless and lossy modes and preserves PNG's alpha transparency. Typical savings when converting a PNG to WEBP are between 50% and 80% depending on the image — often without any visible change in quality.
