About Converting JPG to WebP
JPG is the most widely used photographic image format. Its lossy compression discards detail the human eye barely notices, producing small files that are ideal for photos on the web and in email. When you need to move away from JPG, the usual reason is simple: lossy: quality degrades each re-save.
Converting your JPG image to WebP solves that. WebP is a modern Google image format that offers both lossy and lossless compression plus transparency and animation. It typically produces files 25-35% smaller than JPG or PNG at comparable quality. In practice you gain smaller than jpg and png at similar quality and supports transparency and animation. PrivConvert runs the whole JPG-to-WebP conversion in server memory and deletes your file the instant the WebP is ready — nothing is stored, logged or reused.
