Convert WMV to MP4
WMV is an older Windows Media video format. Outside Windows — on Mac, iPhone, Android, the web or most editing software — it plays poorly, if at all.
MP4 (H.264) is the most universal video format: it opens on every device and publishes to every platform.
Conversion runs in your browser (WebAssembly): your videos are never sent to a server.
WMV vs MP4: what's the difference?
| Criterion | WMV | MP4 |
|---|---|---|
| Origin | Microsoft — Windows Media | International standard |
| On Mac, iPhone, Android | Often unreadable without a dedicated player | Always plays |
| Social media | Generally rejected | Accepted everywhere |
| Editing software | Limited support outside Windows | Universal |
WMV is no problem… as long as you stay on Windows. The moment the video leaves it — a Mac, an iPhone, a website — it becomes a headache. MP4 removes that for good.
When should you convert WMV to MP4?
- Send a video to someone on Mac, iPhone or Android.
- Publish it on YouTube, LinkedIn or social media.
- Import it into modern editing software.
- Archive old Windows videos in a durable format.
