Convert WebM to WMV
Updated Jul 2026
WebM is the video format used by browsers and web recording tools, while WMV is the older format built for Windows Media Player and older Windows software. To convert WebM to WMV, open the file in a converter and export it as WMV. Doing this on your own computer means the video never has to be uploaded anywhere to get it into a format Windows tools expect.

WebM vs WMV: what actually changes
| WebM | WMV | |
|---|---|---|
| Opens everywhere | Well in browsers, spottier in older Windows software | Native support in Windows Media Player and legacy Windows tools |
| File size | Smaller for the same visual quality | Larger, older compression is less efficient |
| Quality | Good, modern compression | Lower ceiling, and re-encoding to WMV adds a second lossy pass |
| Typical source | Screen recordings, browser video, web downloads | Older Windows editing software and legacy media libraries |
| Editing support | Limited in older desktop editors | Wider support in older Windows-only editing tools |
When to convert, and when not to
Convert WebM to WMV when you need a video to open reliably in Windows Media Player or an older Windows program that doesn't recognize WebM.
Keep the WebM if the video is only going into a browser, a modern editor, or a website, since WebM already plays there and re-encoding to WMV just adds an extra generation of quality loss.
Why not just use an online converter?
Screen recordings and browser-captured clips can end up with sensitive content in frame, a private call, an internal dashboard, a document on screen. An online converter means that footage sits on someone else's server while it processes. Converting on your own computer keeps the video, and whatever it shows, on your machine the whole time.
Questions
Does converting WebM to WMV lose quality?
Yes, a little. Both formats are lossy, so re-encoding from one to the other adds a second round of compression on top of the first. It's usually not visible at normal viewing sizes, but it's there.
Will the WMV play in older Windows programs?
That's the point of converting. WMV was built for Windows Media Player and older Windows editing tools, so it opens reliably in software that may not recognize WebM at all.
Is WMV still a good format to use today?
Not really, for anything new. It's an older format kept around mainly for compatibility with legacy Windows software. If you have a choice, WebM or a newer format is the better long-term option.
Can I convert WebM to WMV without uploading the file?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never travels over the internet. You can do it with no network connection at all.
