WMV to MP4 Converter

When you need WMV to MP4

WMV (Windows Media Video) is a Microsoft format that was popular in the 2000s: corporate presentations, training videos, exports from Windows Movie Maker, webcam recordings. These files still appear in company archives and training materials.

The problem is that WMV only works on Windows. On iPhone and iPad it does not play at all, on Mac it requires extra apps, and browsers do not open it. MP4 is the modern universal standard: all devices, operating systems, and video services support it without any extra software.

What changes after conversion

You get the same clip in MP4, which will open everywhere. Quality will not improve - conversion changes the format but does not improve the source. For old WMV files with low resolution from Windows Movie Maker or webcams this is especially important to keep in mind.

During conversion WMV is re-encoded. If the source file is DRM-protected (Windows Media DRM) - as is sometimes the case with corporate materials and content purchased through Microsoft - conversion is not possible. Unprotected files convert without restrictions.

When this is especially useful

• An old corporate training video needs to be played on a modern device or uploaded to the cloud.
• A PowerPoint presentation exported to WMV does not open on the recipient's Mac or iPhone.
• A Windows Movie Maker recording sits in an archive and needs to be converted to a current format.
• A WMV file needs to be uploaded to YouTube or another video service.
• The video needs to play in a browser or be embedded on a website.

What to check before converting

1. Make sure the file is not DRM-protected: if it does not play without a special licence on Windows, it cannot be converted.
2. Check the file plays in Windows Media Player before uploading.
3. Do not expect quality improvement: old WMV files with low resolution will stay the same after conversion.
4. For video below 720p, do not try to increase resolution during conversion - it will not add detail, only make the file larger.

Format and conversion limits

WMV files with DRM protection cannot be converted - this is a legal and technical restriction. The video is re-encoded, quality will not improve. If the file is damaged or incomplete, conversion may not complete. For working with a large file archive, paid limits are available - see current terms on the pricing page.
