How to convert WMV to MP4

Three steps from a Windows Media file to an MP4 that opens on any device

1. Upload the WMV1

The Windows Media video and audio are re-encoded to H.264 and AAC. Resolution, aspect ratio and frame rate stay as they were, so a 4:3 home video keeps its shape.

3. Download and watch it anywhere3

Click “Convert” and save the MP4. It opens in QuickTime Player on a Mac, in the Files app on an iPhone and in Chrome, Safari or Firefox. None of them plays WMV.

WMV rarely plays outside Windows

Microsoft built WMV for Windows Media Player, and macOS, iOS and web browsers have never supported it natively. A clip that played fine on an old PC will not open on a Mac or an iPhone. The MP4 version plays on both.

MP4 selected as the output format for a WMV file

Same picture size, smaller file

H.264 is more efficient than the WMV codecs that most old recordings use. The MP4 keeps the original resolution and frame rate. In our test, a 640 by 480 WMV was about a quarter smaller after conversion.
