Why convert M4V to MP4?

M4V is Apple's MP4 variant and can trip up non-Apple players and editors. Converting to plain MP4 keeps the same video quality while removing the compatibility guesswork.

How it works

Drop your M4V 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.
