M4V to WEBM Converter

Why convert M4V to WEBM?

M4V is Apple's MP4 variant, and the extension alone is enough to make many players and uploaders refuse the file. WEBM with VP9 is the open, royalty-free web format that streams smaller than MP4 at the same quality, so converting turns a file you are stuck with into one you can actually use. Morphix does the whole M4V → WEBM conversion locally with WebAssembly, so even sensitive material never leaves your device.

How it works

Drop your M4V file above and Morphix decodes it locally, then re-encodes it as WEBM 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.
