AVIF usually delivers 40-50% smaller files than JPG at matching quality, which is the biggest single win you can get on image-heavy pages. All current browsers decode it.
Drop your JPG file above and Morphix decodes it locally, then re-encodes it as AVIF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
