Most people convert M4V to ASF for compatibility — a website, app or device insists on ASF, and M4V simply won't open. ASF is widely supported, which makes it a dependable target. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.
It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.
Privacy is the default here. Your M4V file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
