WMV to OPUS: extract audio
Pull the soundtrack out of a WMV video and save it as OPUS. Your video stays on your device: nothing is uploaded.
How to convert WMV to OPUS
- Add your WMV files. Drop one or more .wmv files on the box above, or tap it to pick them from your device.
- Let it convert. The first video you convert loads the converter once (about 31 MB, then cached). After that it runs on your device; a progress bar shows how far along it is.
- Download the OPUS. Press Download next to each file. Nothing was sent to a server, so close the tab and it's gone.
What is a WMV file?
WMV is Microsoft's old Windows Media Video format, common on Windows PCs, old cameras and video downloads from the 2000s.
What is OPUS?
Opus is the audio codec used by WhatsApp voice notes, Discord and video calls. It sounds great at very low bitrates.
Why convert WMV to OPUS?
WMV is great for Windows Media Player and old Windows software, but Macs, iPhones, Android and most websites won't play it. OPUS is the better choice for voice notes and calls; keep in mind many players, editors and upload forms don't accept .opus files.
Will I lose quality?
OPUS uses lossy compression tuned so the difference is invisible to the ear at normal use. We use high-quality settings by default.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your videos never leave your phone or computer.
Questions
Is this WMV to OPUS converter free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
Are my WMV files uploaded?
No. The conversion happens inside your browser on your own device. Nothing is sent to us or anyone else.
Can I convert WMV to OPUS on iPhone or Android?
Yes, in a modern browser. Phones are slower than computers for video, and very long videos can run out of memory on older phones.
Can I convert several files at once?
Yes. Drop as many as you like; they are converted one after another and each gets its own download button.
Is there a file size limit?
No fixed limit, but your browser has to hold the whole file in memory, so files over about 2 GB may fail.
