MOV to WMV Converter
Processing entirely on your device — large files may take a moment.
MOV is Apple QuickTime’s native video container. iPhones and DSLRs record to it, but Windows and Android apps often struggle with it. WMV barely plays outside Windows, so converting to MP4 makes these files usable again.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the MOV format
MOV is Apple's QuickTime container, and technically the elder sibling of MP4 — same ISO base media format, same codec freedom. What sets it apart is professional video: ProRes intermediate codecs, timecode tracks and alpha channels live in MOV, which is why Final Cut, Premiere and every camera that shoots Apple ProRes hand you MOV files.
For everyday sharing it behaves exactly like MP4 (an H.264 MOV is interchangeable in practice). Where it hurts is size: ProRes and other editing codecs run hundreds of gigabytes per hour by design — they prioritize frame-accurate editing over compactness.
+ Strengths
- ✓Native to macOS, iOS and pro editing suites
- ✓Carries ProRes, alpha and timecode tracks
- ✓MP4-compatible for standard codecs
! Limitations
- −Editing codecs produce enormous files
- −ProRes playback needs capable hardware/players
About the WMV format
WMV (Windows Media Video) is Microsoft's codec family, most commonly WMV3/VC-1 inside an ASF container. In its Silverlight-era heyday it delivered good quality at dial-up-to-DSL bitrates and DRM for Windows Media services. Today it survives mainly in corporate archives, old training videos and PowerPoint embeds from the 2000s.
Non-Windows playback was always its weakness and remains so: macOS and Linux need workarounds, phones and web platforms ignore it. Converting WMV to MP4 is the standard exit, and usually saves space at the same time.
+ Strengths
- ✓Good quality-per-bit for its era
- ✓Native Windows Media integration
! Limitations
- −Poor non-Windows and mobile support
- −Obsolete next to H.264
- −DRM variants are device-locked

Frequently asked questions
Is this MOV to WMV converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MOV to WMV?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of WMV, staying in sync with the video. If your MOV file has multiple audio tracks, the first one is used.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
