WMV to OGG Converter
Processing entirely on your device — large files may take a moment.
Windows Media Video and Ogg Vorbis Audio exist for different jobs: WMV is Microsoft’s Windows Media video format, still found in old recordings, webinars and screen captures. Ogg is the standard choice for open-source software, game engines and free platforms.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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
About the OGG format
OGG usually means the Ogg container carrying Vorbis audio — the open-source answer to MP3 from 2000. Vorbis delivered better quality than MP3 at the same bitrate and cost nothing to license, so it spread through game engines (Valve titles), open-source apps and streaming startups. It is technically a container format, so OGG files can also hold Opus or FLAC.
Hardware support was always its ceiling: phones and car systems were slow to add Vorbis, and Opus (also Ogg-based) has since surpassed it technically. Today OGG/Vorbis is best understood as a game-audio and open-ecosystem format.
+ Strengths
- ✓Royalty-free with good quality-per-bit
- ✓Native in game engines and open-source stacks
- ✓Container flexibility (Vorbis/Opus/FLAC)
! Limitations
- −Patchy hardware and car support
- −Technically surpassed by Opus

Frequently asked questions
Is this WMV to OGG 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 WMV to OGG?
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 OGG, staying in sync with the video. If your WMV file has multiple audio tracks, the first one is used.
Does converting WMV to OGG re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
