The video stream has to be fully re-encoded: WMV typically carries WMV9, and F4V expects H.264. That means a real transcode, so allow for processing time and a small generational quality cost.
At 1080p, WMV typically runs around 6 Mbps while F4V sits near 6 Mbps, which is the main driver of the size difference you will see.
This is an older container, introduced in 2007, and browsers will not play it directly. It is best suited to archival or a dedicated player.
This page converts WMV files, stored in the ASF container since 1999, into F4V, which uses Flash MP4 and dates from 2007. The differences between the two containers decide what changes in the result.
WMV comes from Microsoft and dates to 1999. It carries WMV9, VC-1, which is what determines the quality ceiling of anything you convert out of it.
F4V was introduced by Adobe in 2007. It carries H.264 and has native playback on 0 of six platform categories, which is the practical reason to choose it as a target.
