How to convert MP4 to WMV
WMV (Windows Media Video) is a Microsoft video format that was widely used on Windows PCs in the 2000s and early 2010s. It is still required by some older corporate video systems, Windows Movie Maker projects, and Silverlight-based video players. Converting MP4 to WMV produces a file compatible with these Windows-centric environments.
BoltConverter converts MP4 to WMV on its servers. The video is encoded using the WMV3 codec (Windows Media Video 9), which is the standard WMV format for most compatibility scenarios.

Frequently asked questions
Why would I need a WMV file instead of MP4?
WMV is needed for compatibility with older Windows Media Player versions, some corporate intranet video systems, older Windows-only video editors, and any workflow that was built when WMV was the standard Windows format.
Will there be quality loss?
Yes. Converting from MP4 to WMV re-encodes the video, which causes a small generational quality loss.
Can I play WMV files on a Mac?
WMV is not natively supported by macOS. You need VLC or Flip4Mac installed to play WMV files on a Mac.
Is there a size limit?
BoltConverter accepts MP4 files up to 100 MB for conversion to WMV.
Are my files kept private?
Your file is uploaded over HTTPS and deleted from the server immediately after conversion.
