Convert WMV to AVI — Free Online Converter

WMV and AVI are both Microsoft video formats from different eras. WMV uses the ASF (Advanced Systems Format) container with VC-1 or WMV2 codecs, designed for streaming and DRM. AVI (Audio Video Interleave, 1992) uses the RIFF structure and is a simple, universally recognized container that works with virtually any editing software and media player. Converting WMV to AVI moves content from Microsoft's streaming format to its simpler, more compatible container — useful for legacy editing software, hardware players, and systems that support AVI but not ASF.

Some video editing applications (especially older versions of VirtualDub, Avidemux, and Windows Movie Maker) work natively with AVI but cannot import WMV/ASF files. Hardware media players and set-top boxes from the pre-streaming era often support AVI (with DivX/XviD) but not WMV. Converting to AVI also strips any Windows Media DRM that might be present, producing an unprotected file (from DRM-free sources only).
