How to convert MP4 to WMV
- Add your .MP4 file - drop it in the box above or click to browse.
- Convert it to .WMV in a few seconds.
- Download your new .WMV file.
What to expect
- Re-encoding is unavoidable - WMV and MP4 use different video codecs, so some quality loss always occurs; keep the output bitrate close to the source to minimise it.
- WMV files are typically larger than MP4 at the same quality because the Windows Media Video codec is less efficient than H.264.
- Audio is re-encoded from AAC to WMA, and any embedded subtitles or chapter markers in the MP4 are not carried over to WMV.
Frequently asked questions
Can I convert MP4 to WMV without quality loss?
No - full re-encoding is required, which always introduces some loss. Setting the output bitrate at or above the source bitrate keeps the difference minimal.
Does HandBrake support WMV output?
Recent versions of HandBrake dropped WMV output; use ffmpeg or a dedicated converter like FormatFactory instead.
Will the WMV file be smaller than the MP4?
Usually not - WMV is less efficient than H.264, so the output is often larger at equivalent quality.
How long does conversion take?
A 10-minute 1080p MP4 typically converts in 2-5 minutes on a modern computer using ffmpeg with default settings.
