How to Do a WMV-to-MP4 Conversion

Edited by Pat Bitton

August 29, 2019

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.

WMV (Windows Media Video) is a video compression format that was initially designed for storing videos in Windows. WMV is not natively supported by many other operating systems or portable devices.

MP4 (MPEG-4 Part 14) is a video file format that can contain video, audio, and subtitles. This format is one of the most widely used and is supported by many different operating systems and devices.

These days, there are two main ways of converting WMV to MP4 – using desktop software or an online converter. So let’s have a look at pros and cons of each method and also learn the difference between WMV and MP4 formats.

How to Convert WMV to MP4 Using Movavi Video Converter

The first WMV conversion method is to use Movavi Video Converter. This is a high-speed application for converting WMV files to any popular format, including MP4, MPEG, AVI, and MKV. Once you've converted your files, you will be able to watch your movies on your preferred device. Movavi Video Converter also provides batch processing and lossless conversion, for the best user experience. Download the Windows or Mac version of the program and start right away!

Follow the steps below to learn how to convert WMV to MP4.

Download the WMV-to-MP4 Converter

First download and run the installation file. Follow the simple directions on how to install Movavi Video Converter.

Add WMV Files to the Program

Hit the Add Media button, choose Add Video, and add the files for which you want to change the format. Movavi Video Converter supports batch file conversion, so you can select as many files as you want.

Edit the Added Files (Optional)

You can edit the files you’ve uploaded to the program by accessing the built-in editor via the Edit button on the right.

In the Stabilization tab, you can get rid of any shakiness in the videos. In Audio, change the sound level or remove background noise. In the Adjustments tab, alter the saturation, contrast, brightness, and other settings. Apply stylish filters from the built-in library in the Effects tab. Add a watermark or insert subtitles in the Watermark and Subtitles tabs, respectively. In the Crop, Trim, and Rotate tabs, do away with black video borders, trim away unwanted footage, and rotate your clips.

Compress the WMV Files (Optional)

Use the software to reduce the size of over-large files. You can find the size of your file in the description and click on it. Specify the size, bitrate, and quality in the box that opens. Hit Convert sample if you want to check the quality of a small part of the file before converting it.

Select an Output Format

After adding your video files, open the Video tab, expand the MP4 category, and select your preset: you can choose either Same as input so that the resolution remains the same or the specific resolution you'd prefer.

Start Converting WMV to MP4

Make sure where your converted files will be stored. If you need to specify or change the destination folder, choose a different path by hitting the Save to button.

To start the conversion, click the Convert button. The folder with your new files will open automatically as soon as the conversion process is complete.

As you can see, this is a pretty simple and straightforward program. Movavi Video Converter also has another great advantage – flexibility. In addition to converting WMV to MP4, the software can help you convert your videos to any of the 180+ supported formats, and you can use it for almost all your formatting needs. Whichever multimedia files you want to convert, you'll always get the best output quality.

How to Convert WMV to MP4 Online

Another approach for changing the format of WMV files is to use an online service like This handy website may be helpful if you need to convert your video quickly without having to spend time installing software. First, click Add Your Media to upload the video you want to convert from your computer. In the open window, select the desired file and click Open. Then hit the Convert button to launch the process. After the file has been converted, you’ll be able to download the new file in MP4 format.

Despite being so user-friendly, the service does have a couple of restrictions – the file size it can handle is limited, and you can only convert one file at a time. While it’s fair to say that this online service is convenient for a one-time conversion, it lacks the editing capabilities and compression preferences implemented in the desktop software.

How to Convert WMV to MP4 for Free

Another option to change the format of your files is to use a free WMV-to-MP4 converter, such as the VLC media player. Even though it primarily functions as a video player, the VLC media player also enables file conversion to popular formats.

Download the appropriate version of VLC

Install the player on your computer and launch it. Click Media in the top left of the program window and select Convert / Save. Next, click the Add button to upload your file for conversion. Hit Convert / Save and select MP4 as the target format. Click the Browse button to choose the destination folder for the converted file and enter a file name. To convert the file, click the Start button.

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.
