3GP is the low-bitrate format old handsets recorded to, and desktop players usually stare blankly at it. 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 3GP → MKV conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your 3GP 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.
