JPG to WEBP converts your JPG images into WEBP, a modern format that typically produces noticeably smaller files at similar visual quality — great for speeding up websites and saving storage.
Adjust the quality to find the right balance and convert many images at once. Conversion happens entirely in your browser, so your images are never uploaded. Creating WEBP files needs a recent version of Chrome, Edge, or Firefox.
