About the JPG to WEBP Converter
JPG has been the standard for photographic web images for decades, but WEBP outperforms it on almost every metric relevant to the web. Google's WEBP format typically achieves 25–35% smaller file sizes than JPG at comparable visual quality. It also supports transparency (which JPG does not), though converting a JPG to WEBP won't add transparency — the existing solid background is preserved.
