The video stream has to be fully re-encoded: 3GP typically carries H.263, and WMV expects WMV9. That means a real transcode, so allow for processing time and a small generational quality cost.
Embedded subtitle tracks will be lost. 3GP can carry them inside the file; WMV has no place to store them, so export them separately first if you need them.
At 1080p, 3GP typically runs around 1.1 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 3GP files, stored in the 3GPP container since 2001, into WMV, which uses ASF and dates from 1999. The differences between the two containers decide what changes in the result.
3GP comes from 3GPP and dates to 2001. It carries H.263, MPEG-4 Part 2, H.264, which is what determines the quality ceiling of anything you convert out of it.
WMV was introduced by Microsoft in 1999. It carries WMV9, VC-1 and has native playback on 1 of six platform categories, which is the practical reason to choose it as a target.
