Why Convert WEBM to WMV?

Converting WEBM to WMV is a common task whenever a file has to work somewhere that expects the other format. WMV is the Windows Media Video format that Microsoft introduced in 1999 for streaming and playback on Windows. This converter makes the switch locally in your browser — nothing is uploaded.

Common use cases

  • You have a WEBM file and need it in WMV format.
  • The target software or platform requires WMV but your file is in WEBM.
  • Typical use of WMV: Opening old Windows recordings on a phone, tablet or Mac.
  • You want to reduce file size or improve compatibility without using desktop software.
Keep in mind: Browsers and phones cannot play WMV natively and the format is considered obsolete. Files created here use the classic WMV2 codec for maximum Windows compatibility.
