Summary:
WMV is Microsoft's video format built on the ASF container. It is known for its small file size and DRM support and is widely used on Windows, but it struggles on macOS. Here's how it compares to other formats, how to play it on any device, and when to convert.
WMV, which stands for Windows Media Video, is a video format owned by Microsoft. It is developed to store and stream compressed videos and uses the .wmv extension. It can contain video encoded with Windows Media Video and is used for Windows applications and older digital media services. If you have an old WMV video, you may wonder how to open and play it on other devices. In this post, we will explain what a WMV file is and compare it to other formats. Also, we will introduce where it is supported and how to convert it.
A WMV file, also known as the Microsoft format, is a video format created and owned by Microsoft. It uses the Windows Media Video codec within the ASF container and carries the .wmv extension. WMV uses lossy compression to minimize the file size while maintaining reasonable video quality. It also supports DRM to control how protected videos are accessed or used. Better yet, WMVs use various bitrates, ranging from low to much higher. WMV integrates well with Microsoft and Windows software, but it is less compatible than modern formats.
| Format | Quality | Bitrate | File Size | Mac Support | Streaming | Best For |
|---|---|---|---|---|---|---|
| WMV | Good picture quality | Good efficiency for older standards | 200 to 400 MB for a 5-minute video | When comparing WMV vs MP4 in terms of Mac support, WMV is a Windows-native format | Older intranet streaming | Windows-only sharing, PowerPoint embedding, and low-bandwidth streams |
| MP4 | Excellent quality at smaller file sizes | Best efficiency | 150 to 300 MB for a 5-minute video | Fully native | Universal web streaming | Web streaming, smartphones, and sharing |
| AVI | Can store lossless or uncompressed video | Old and inefficient | 500 MB to 1 GB for a 5-minute video | Older container format | Not online delivery | Storing uncompressed footage |
Windows Media Player natively supports opening WMV files because it was developed by Microsoft. It can open the file directly in File Explorer if using a supported codec, without additional software.
To open: Open the folder containing the .wmv video in the File Explorer. Right-click the file, click Open With, and select Windows Media Player. The WMV video should begin playing automatically.
How to play WMV on Mac? Mac has a built-in QuickTime Player for playing media files. However, QuickTime alone cannot play WMVs on Mac. You need Flip4Mac to let it play WMV files.
To play: Download the Flip4Mac installer package first and install it on your Mac. Go to System Preferences, click Flip4Mac, and open the Player tab. Check the box for Open local files immediately to enable playback. Next, double-click the WMV file, select Open With, and choose QuickTime Player.
Android devices do not natively support WMV playback, so they require a third-party media player to play them. VLC supports nearly all video formats, meaning WMV can be played with it.
To open: Get VLC from the Play Store and install it on your Android device. Open the media player and allow media access, then find the WMV file in your folders. Tap it to start playback.
Roku devices and Chromecast setups cannot natively play WMV files, while smart TV models offer mixed, brand-dependent support. However, they are increasingly being phased out. The best way to ensure error-free playback is to change WMV to MP4.
Old WMV file formats seem small compared to AVI or even some MP4s. In practice, they are smaller due to aggressive lossy compression and low encoding bitrates. It is not because the .wmv extension magically produces smaller files. If two videos have different sizes, check their codec and bitrate first. These factors explain the difference far better than the file format name alone.
In today’s time, WMV files are rarely used. Macs, DVDs, and modern devices use ProRes, MPEG-2, and MP4 formats instead. Apple ProRes is used in video editing and is supported by many Mac video editing software. DVDs require MPEG-2-compatible video for authoring and burning. Notably, MP4 with H.264 video is the standard format used by browsers, smartphones, smart TVs, and video platforms such as YouTube.
For most people, MP4 is the preferred format because of its high compression and universal support. Choose WMV when you are working with an existing Windows-based archive or application that expects Windows Media files. If you’re looking for the best WMV converter, you can use AnyMP4 Video Converter Ultimate. This tool supports batch conversion across 500+ formats at 120× speed without lag or crashes.

3. Enable the Hardware Acceleration button to speed up the conversion. Set the destination path, then click Convert All to batch-convert WMV to MP4.
WMV files uses lossy compression, meaning converting it to another lossy format decodes and re-encodes the video again. As a result, it may lead to a reduction in quality. Remember to use the right format for your intended use.
A WMV file can be DRM-protected, but raw WMV files are unencrypted and unprotected. DRM is only applied to WMV if it was distributed commercially, purchased, or downloaded from subscription-based platforms that encoded it with Microsoft's copy-protection system.
Is WMV better than MP4?
In terms of universal compatibility, MP4 is better than WMV. Nearly all devices, phones, platforms, and operating systems can handle MP4 formats. WMV only works best on Windows Media Player and PowerPoint.
How do I convert WMV to MP4 for free?
You can use a free online WMV-to-MP4 conversion tools to convert WMVs to MP4 format without charge. However, please be informed that such tools have daily upload size and conversion limits.
Can I still use WMV in 2026?
While it is outdated, you can still use it and open WMV files on a Windows PC. However, for web use, sharing, and non-Windows OS, use the MP4 format instead.
Now that you know what a WMV file is, you can see that this format is still useful today. However, it has compatibility issues on modern devices, phones, and platforms. To make it compatible, convert it to a universal format, like MP4, using AnyMP4 Video Converter Ultimate. This software can convert hundreds of WMVs in batches at 120× speed.
