About Windows Media (WMV)
Windows Media Video (WMV) is Microsoft's family of video codecs, stored in the ASF container.
Older Windows software, Windows Movie Maker projects and video from the 2000s.
WMV files can carry DRM, and many devices outside Windows do not play WMV.

Why does my WMV video refuse to play on my Mac or iPhone? Windows Media Video uses Microsoft codecs that Apple and Android devices don't include, so a conversion to MP4 is the quickest fix.
About AAC
AAC (Advanced Audio Coding) is the lossy audio codec standardised in MPEG-2 and MPEG-4 as the successor to MP3; at the same bitrate it generally sounds better than MP3.
It is the audio in most MP4 videos, in Apple Music and on YouTube; a .aac file is a bare AAC stream without a container.
A bare .aac stream has only limited room for tags and cover art, so music players usually expect AAC inside an M4A file.
Why convert music to AAC instead of MP3? At the same bitrate AAC sounds better, and every modern phone, computer and streaming service decodes it.
What changes when you convert WMV to AAC
- The soundtrack of the WMV is re-encoded as AAC at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the AAC file contains the audio track of your WMV, and the picture is dropped.
- WMV files can carry DRM copy protection; protected files are detected and refused, because copy protection is never removed.
Settings you can change
Before you convert WMV to AAC, you can adjust: Audio codec, Rate control, Audio bitrate, Quality (VBR), Sample rate, Channels, Normalize loudness, Trim start, Trim duration, and Keep tags.
