Convert WMV to OGG
Updated Jul 2026
WMV is Windows' native video format, and OGG (Ogg Vorbis) is an audio format used by games and many media players. Converting WMV to OGG pulls the audio track out of the video and re-encodes it, discarding the picture entirely. Doing this on your own computer means the video never has to leave your machine to get the sound out of it.

How to convert WMV to OGG
- Open Morphjet and drag in the WMV file or a whole folder of them.
- Choose OGG as the output format. Only the audio track will be kept, the video is dropped.
- Convert. The OGG file is written next to your original, and nothing leaves your machine.
WMV vs OGG: what actually changes
| WMV | OGG | |
|---|---|---|
| Contains video | Yes | No, audio only |
| File size | Larger, video plus audio | Much smaller, audio alone |
| Quality | Lossy compression tuned for picture and sound together | Lossy audio compression, quality depends on the bitrate you pick |
| Compatibility | Plays natively on Windows, limited support on Mac and mobile | Supported by many media players and games, not native to Windows Media Player or Apple's apps |
| Typical use | General-purpose Windows video | Game audio, streaming audio, and players that favor an openly licensed format |
When to convert, and when not to
Convert WMV to OGG when you only need the sound from a video, such as pulling out a lecture, a voiceover, or a music track, and you want a smaller audio file in a format many games and media players accept without licensing restrictions.
Keep the original WMV if you actually need the picture, since converting to OGG throws the video away for good.
Why not just use an online converter?
An online converter that extracts audio from a WMV still has to receive the whole video file first, meaning a stranger's server sees the full footage just to hand you back a sound file. Converting on your own computer skips that step entirely. The video and the audio it contains never leave your machine.
Questions
Does converting WMV to OGG keep the video?
No. OGG is an audio-only format, so the conversion extracts the soundtrack and discards the picture. If you need to keep the video, convert to a video format instead.
Will the audio lose quality?
Some. WMV's audio is already compressed, and re-encoding it to OGG compresses it again, so there's a small additional loss. For spoken word or background music it's usually not noticeable, especially at a reasonable bitrate.
Why convert to OGG instead of MP3?
OGG is a format that isn't tied to one company's licensing terms, which is why it shows up as the audio format of choice in a lot of games and open media players. If you specifically need an OGG file for one of those, that's the reason to pick it over MP3.
Does the OGG file keep the title or other tags from the WMV?
Basic tags like a title sometimes carry over, but WMV's metadata doesn't map cleanly onto OGG's tagging system, so don't count on everything transferring. Worth checking the output file's info after converting.
Can I do this without uploading the video anywhere?
Yes. A desktop app like Morphjet extracts and converts the audio on your own computer, so the WMV file never has to travel over the internet.
Morphjet converts WMV, OGG, and 1,800+ other formats, all on your machine. Launching this July.
