GIF's 256-colour palette and ancient compression make it the heaviest way to ship a modern image. AVIF encodes the same frame with full colour depth at a fraction of the weight, so pages load faster and mobile visitors burn less data.
Drop your GIF 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.
