AMR is the narrowband codec old phones recorded voice memos in, and barely anything plays it today. WMA is the Windows Media audio format older Windows software, car head units and voice recorders still expect, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole AMR → WMA conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your AMR file above and Morphix decodes it locally, then re-encodes it as WMA 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.
