Why convert 3GP to MP4?

3GP was built for old mobile networks and chokes most editors. MP4 is the standard container for social uploads, timeline editing and playback on every current device.

How it works

Drop your 3GP file above and Morphix decodes it locally, then re-encodes it as MP4 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.
