AVIF is the newest web image codec, so anything older than a couple of years — editors, CMS uploaders, phones on old firmware — simply cannot open it. ICO is the format Windows, Electron apps and browser favicons require, with the icon sizes packed into a single file, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole AVIF → ICO conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your AVIF file above and Morphix decodes it locally, then re-encodes it as ICO 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.
