WMV is the Windows Media Video format from Windows XP and Windows Movie Maker. Macs, phones and most web players can’t open it.
Browsers can’t decode WMV, so the page loads ffmpeg (about 32 MB, once) and re-encodes the video to H.264 with AAC sound. It runs on your computer, so nothing is uploaded. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
How to convert WMV to MP4
- Drop your WMV file on the box above.
- MP4 is already selected. You can pick another format if you need one.
- Press Convert to MP4 and download the new file.
Questions
Does it work with ASF files?
Yes. ASF is the container WMV uses. Drop it on the video converter.
How long does it take?
WMV has to be fully re-encoded. Expect a few times the video’s length.
Can it open protected WMV files?
No. DRM-protected files can’t be converted.
