How to do a WMV to MP4 conversion

Edited by Ben Jacklin

If you are a PC user, you’re probably familiar with WMV, which stands for “Windows Media Video”. Originally developed by Microsoft, this format works well on Windows and even Mac with the help of Windows Media Player, but it’s not very friendly with other operating systems. So if you want to watch a video in WMV on your mobile device, it would be best to transfer it to a more compatible video format, like MP4. You can convert WMV to MP4 online using the tool at the top of this page. Alternatively, try desktop conversion software.

In this article, you’ll learn how to convert WMV to MP4 using Movavi Video Converter. You’ll also find a comparison table describing the two formats and answers to frequently asked questions.

WMV vs. MP4 comparison

WMV and MP4 are both popular video formats but let’s see what makes them different from each other.

WMV (Windows Media Video) is a video container format developed by Microsoft. Today it’s seen as a rather old-fashioned format which is best suited for use on Windows; other operating systems may experience problems playing this video format. Its codecs and compression algorithms are less technologically advanced than those of MP4, which primarily uses H.264 and H.265 codecs.

MP4 (MPEG-4 Part 14) is a container format used for storing video and audio streams. This format provides high compression levels and relatively low quality loss, which makes it one of the most widely used formats on the internet. Over the course of time, MP4 has become a truly universal format and can be played on almost any desktop or portable device.

So, in the end, there is one main point that you should focus on when deciding which of the two formats to use – the operating system. If you want to play your WMV videos only on a Windows system, it’s fine to keep your files the way they are without conversion. But if you’re thinking of playing them on other platforms or mobile devices, then converting WMV to the more advanced MP4 format is the better solution.
