Leave Windows Media behind
WMVs won't open on Mac, iPhone or many TVs; MP4 will.
Codecs covered
WMV2/WMV3 (VC-1) and WMA audio decode in the browser.
Honest about limits
If a WMV carries an exotic codec that fails, the error says so clearly.
Private
The video never leaves your device: ffmpeg runs in your browser.
Frequently asked questions
Do all WMVs work?
The vast majority (WMV2, WMV3/VC-1 with WMA). Some rare DRM or Screen-codec profiles may fail; in that case you'll get a clear error, never a corrupted result.
Does it work with DRM-protected WMV?
No: Windows Media DRM files can't be converted, and we don't try to bypass that protection.
Is quality lost?
The CRF 23 re-encode keeps high visual fidelity.
How long does it take?
Like any in-browser re-encode: roughly real-time or a bit more, depending on your machine.
