Convert JPG to WebP Online

Need to turn a JPG file into WebP? JPG (also written JPEG) is the world's most widely supported photo format. It uses lossy compression that throws away detail the eye barely notices, which keeps photographic files small while staying compatible with virtually every device, browser and app. WebP is a modern format from Google that compresses far better than JPG or PNG at the same quality. It supports both lossy and lossless modes, transparency and animation, which makes it the format of choice for fast-loading websites. Converting from JPG to WebP bridges the two: you keep the picture, but in a format that fits where you are taking it.
