OGV is the Theora-era open video container that survives in wikis and archives and plays almost nowhere else. 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 runs the whole OGV → MKV conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your OGV 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.
