The video stream has to be fully re-encoded: AVI typically carries MPEG-4 Part 2, and WMV expects WMV9. That means a real transcode, so allow for processing time and a small generational quality cost.
Only one audio track will be kept. AVI can hold several, for example alternate languages, but WMV supports a single track.
WMV is built for streaming and progressive download, so the result starts playing before it has fully loaded, which the source format does not do well.
At 1080p, AVI typically runs around 7 Mbps while WMV sits near 6 Mbps, which is the main driver of the size difference you will see.
This is an older container, introduced in 1999, and browsers will not play it directly. It is best suited to archival or a dedicated player.
This page converts AVI video, stored in the RIFF AVI container since 1992, into WMV, which uses ASF and dates from 1999. The codecs each container accepts decide whether the picture has to be re-encoded.
AVI comes from Microsoft and dates to 1992. It usually holds MPEG-4 Part 2, DivX, or Xvid video with MP3, PCM, or AC-3 sound, and those streams set the ceiling for anything converted out of it.
WMV comes from Microsoft and dates to 1999. It holds WMV9 or VC-1 video alongside WMA audio, and without installing anything it plays on Windows.
