WMV is Microsoft's old video format, which macOS, iOS and most editors cannot open without extra codecs. MKV is the flexible open container that keeps every audio track, subtitle and chapter in one file, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole WMV → MKV conversion locally with WebAssembly, so even sensitive material never leaves your device.
Drop your WMV file above and Morphix decodes it locally, then re-encodes it as MKV 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.
