MKV can hold multiple audio tracks, subtitles and chapters, which is exactly why phones and TVs choke on it. ASF is the Windows Media streaming container legacy Microsoft media servers and players ingest, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole MKV → ASF conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your MKV file above and Morphix decodes it locally, then re-encodes it as ASF 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.
