What does converting JPEG to WEBP mean?
JPEG is a lossy format optimized for photographs (identical to JPG), while WEBP is a modern format developed by Google that combines strong compression with wide browser support. WebP offers better compression than JPEG at equivalent quality — reduce file size by up to 30%.
JPEG — the same format as JPG under a different file extension — uses lossy compression tuned to human perception, producing small files ideal for photographs at the cost of some fine detail and no transparency support.
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.
