What does converting JPG to WEBP mean?
JPG is a lossy format optimized for photographs, while WEBP is a modern format developed by Google that combines strong compression with wide browser support. WebP offers better compression than JPG at the same quality, reducing file sizes by up to 30%.
JPG uses lossy compression tuned to how the human eye perceives detail, producing much smaller files than PNG for photographic content. It doesn't support transparency, and repeated re-saving can introduce visible compression artifacts over time.
WebP supports both lossy and lossless compression plus transparency and animation in a single format, typically producing files 25-35% smaller than JPG or PNG at equivalent visual quality. It's supported by all major modern browsers.
