Pulling the soundtrack out of a .mov video into .wma audio keeps what you can hear and drops the picture entirely. A .mov file is Apple's QuickTime movie container, which stores video, audio, text, and timecode tracks in a flexible atom-based layout. iPhones, iPads, and professional cameras that record ProRes all write .mov, so the extension shows up constantly in editing workflows.
A .wma file contains Windows Media Audio, Microsoft's proprietary compressed format, wrapped in the same ASF container as WMV video. It shipped with every copy of Windows for a decade, so ripped CDs and store purchases from that era survive as .wma libraries. For this route the practical draw is respectable quality at mid bitrates for its era and still opens on any Windows PC without extra software — balanced against proprietary and effectively abandoned, which is worth knowing before you commit a large batch.
Why convert MOV to WMA?
The usual reason to take .wma audio out of a .mov file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, proRes recordings consume enormous disk space; on the target side, the payoff is respectable quality at mid bitrates for its era, which is exactly what you want for converting old ripped-CD libraries to MP3 or FLAC.
MOV vs WMA at a glance
| Aspect | QuickTime video (.mov) | Windows Media audio (.wma) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | media lives in a hierarchy of atoms, each declaring its own size and type, which makes the format easy to extend | the standard codec is a lossy transform coder supporting up to 48 kHz stereo |
| Strongest at | importing iPhone footage into an edit without conversion | converting old ripped-CD libraries to MP3 or FLAC |
| Weak spot | proRes recordings consume enormous disk space | proprietary and effectively abandoned |
| Metadata | quickTime metadata atoms and keys, including camera model, location, and timecode data written by iPhones and professional cameras | aSF attributes mirror ID3 basics such as title, artist, album, and artwork, and Windows Media Player wrote extended library fields on top |
Pick WMA as the output
Select .wma in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WMA is selectable, the route is real and validated.
Convert on your device
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WMA file. Outputs keep the original filename with the .wma extension.
MOV to WMA questions, answered
Will converting MOV to WMA lose quality?
Since mov is container-oriented and wma is lossy-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .wma itself requires.
Is it private to convert MOV files here?
Yes — the .mov file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Where will the WMA file work?
Windows continues to play .wma through its bundled apps, but macOS, iOS, Android, and all web browsers lack native support. Files protected by Windows Media DRM will not play anywhere now that their license servers are gone.
Will the WMA file be bigger or smaller than my MOV?
Much smaller — the video stream is usually 80–95% of a .mov file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
What happens to the metadata in my MOV file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, quickTime metadata atoms and keys, including camera model, location, and timecode data written by iPhones and professional cameras; none of it is transmitted anywhere because the file never leaves your browser.
