Why convert MP4 to AVI?

Some legacy editing software, DVD authoring tools and industrial players only accept AVI. Converting keeps your footage usable on that older hardware and software chain.

How it works

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