MKV can hold multiple audio tracks, subtitles and chapters, which is exactly why phones and TVs choke on it. 3GP is the compact mobile container built for very low bandwidth, ideal for feature phones and MMS-era hardware, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole MKV → 3GP 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 3GP 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.
