JFIF downloads are ordinary JPEGs with an extension Windows and many upload forms refuse to recognise. ICO is the format Windows, Electron apps and browser favicons require, with every icon size packed into a single file, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole JFIF → ICO conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your JFIF 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.
