Why Convert WMV to MP4?

WMV is Windows Media Video, and it shows: Macs, iPhones, iPads, and most non-Windows players either refuse it or need an extra codec to limp through. MP4 skips all of that.

H.264 video with AAC audio plays natively on every device without anyone installing anything first.

Frequently Asked Questions

Can I convert WMV to MP4 in the browser?
No. Browsers cannot decode the Windows Media codecs, so this pair runs in the desktop app through FFmpeg. The file stays on your Mac; nothing is uploaded.
Why won't my WMV play on my Mac or iPhone?
Apple never shipped Windows Media support. WMV was built for Windows Media Player, so outside the Microsoft ecosystem it needs conversion or a third-party codec to play at all.
What codec does the output MP4 use?
H.264 video with AAC audio, the combination supported by effectively every device, browser, and player made in the last fifteen years.
Are DRM-protected WMV files supported?
No. Old WMV files wrapped in Windows Media DRM cannot be converted. Only unprotected files go through.
Is my file still private in the desktop app?
Yes. The desktop app converts with native engines on your Mac and works offline after a one-time activation check. Nothing is uploaded, in the browser or on desktop.

Converting a Windows video archive?
