If you want to merge WMV files with lossless quality, this is the perfect tutorial. The internet is filled with multiple online and dedicated WMV mergers for computers and mobiles. However, just a handful of these programs guarantee lossless results. Also, most WMV editors have limited file size support. So, to be safe, this guidepost discusses the best solutions to merge WMV without quality loss.

Part 1. What is a WMV file?

Before we dive deeper into discussing the best apps to merge WMV, let's first see what precisely this file format is. Basically, WMV (Windows Media Video) is a video format developed by Microsoft in 2013. It features a .wmv filename extension and saves three distinct video codecs: H.262 (MPEG-2), (MPEG-4), and Blu-ray video disc. As expected, WMV can be opened by almost any media player on Windows operating system.

Theoretically, WMV boasts a smaller file size than MP4, thanks to its superior compression. However, MP4 edges it out in terms of quality because WMV still uses old codecs like WMV1 and WMV2. Also, MP4 is universal, unlike WMV, which is mainly confined to Windows platforms. Nonetheless, these file formats are almost evenly matched in most other aspects.
