WMV to OGA Converter

How to Convert WMV to OGA Online

1. Upload Your WMV File: Drag and drop or click "+ Add Files" to select one or more.wmv files from your computer. Batch conversion is supported — every file inherits the same audio settings, which keeps a folder of clips consistent without re-clicking.
2. Pick Codec and Quality Preset: Default is Vorbis at the Highest preset. Choose Opus for the smallest size at speech and music bitrates (32-128 kbps), FLAC for lossless archival, Speex if you need legacy compatibility with old VoIP pipelines, or PCM if you want raw uncompressed samples wrapped in Ogg. Switch from preset to Constant Bitrate (e.g. 128 kbps) or Variable Bitrate when you need a specific target.
3. Set Sample Rate, Channels, and Trim (Optional): Audio Sample Rate accepts 8000-48000 Hz (44100 Hz matches CD, 48000 Hz matches video); Audio Channel toggles between Mono and Stereo; Trim lets you set a start time and duration in HH:MM:SS.ms to extract a single clip rather than the whole track. Specific file size and File Compression sliders also let you target a byte budget.
4. Convert and Download: Click "Convert". Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared. Download individually or as a ZIP when batch converting.

Why Convert WMV to OGA?

WMV is Microsoft's Advanced Systems Format (ASF) video container with WMV-codec video and Windows Media Audio (WMA) audio. It first shipped with WMV 7 in 1999, and WMV 9 was standardized as SMPTE 421M (VC-1) in March 2006. OGA is the audio-only Ogg container that Xiph.Org and RFC 5334 (September 2008) carved out from the original.ogg extension — it carries Vorbis, Opus, FLAC, Speex, or OggPCM streams under the audio/ogg MIME type. Going WMV to OGA strips video and re-encodes the audio into a royalty-free, patent-unencumbered open format that ships natively in Firefox, Chrome, Android, and most Linux distros, and side-steps WMA's Microsoft-licensed lineage.

• Web audio embedding — <audio> element fallback chains like Opus → MP3 cover every modern browser; OGA with Vorbis or Opus is the lightweight Firefox/Chrome leg of that chain.
• Podcast and lecture archives — extract just the dialogue from a 200 MB WMV lecture recording into a 15-20 MB Opus OGA file at 48 kbps, with no audible loss for speech.
• Open-source and Linux pipelines — GStreamer, VLC, Audacity, and Rhythmbox all play OGA natively without proprietary codec packs; WMV/WMA need gstreamer1.0-plugins-ugly or equivalent.
• Game audio assets — Godot, Unity, and many indie engines accept Ogg Vorbis as a first-class loop-friendly format with no per-title licensing fees (unlike MP3 before its patent expiry).
• Long-term archival — FLAC inside OGA gives bit-perfect lossless storage at roughly 50-60% of the WAV size, and the codec is fully open so you'll be able to decode it in 20 years.
• Stripping video for transcripts — feed the OGA into Whisper, Otter, or any speech-to-text pipeline; you don't need the picture for a transcript and audio-only uploads are faster.

Frequently Asked Questions

Will converting WMV to OGA keep only the audio?

Yes — that is the point of the conversion. The.oga extension is reserved for audio-only Ogg files (per RFC 5334), so the video stream is discarded and only the audio track is re-encoded. Any subtitles, metadata, or chapter markers embedded in the ASF container are also dropped; the OGA will carry only basic Vorbis/Opus comments (title, artist, album, encoder).

Should I pick Vorbis or Opus for the OGA output?

Opus, in most cases. It was standardized as RFC 6716 in 2012 and outperforms Vorbis at every bitrate from 6 kbps speech up to 510 kbps transparent music. The only reason to still pick Vorbis is hardware compatibility — some older portable players and embedded firmware decode Vorbis but not Opus. For anything web-, mobile-, or desktop-based in 2026, Opus gives smaller files at the same quality.

Why is my OGA file larger than I expected?

Two common causes. First, you may have selected FLAC (lossless) without realising — FLAC files at 16-bit/44.1 kHz typically run 700-1000 kbps, roughly 5-7x the size of a 192 kbps Vorbis file. Second, the Audio Quality Preset defaults to Highest, which uses the upper end of the codec's bitrate range. Switch to Medium or pick a Constant Bitrate around 128 kbps for music or 64 kbps for speech if you want a smaller file.

Can my browser or phone play.oga files natively?

Yes, mostly. Firefox, Chrome, Edge, and Opera have decoded Ogg Vorbis and Opus for over a decade. Safari added Opus in version 11 (2017) and Opus in WebM is supported across Apple platforms;.oga specifically may need to be served with Content-Type: audio/ogg to play in some Safari versions. On Android, Vorbis has shipped since Android 1.0 (2008) and Opus since Android 5.0 (2014). iOS plays Opus via the Ogg container in recent versions; for maximum compatibility you may still want to ship an MP3 fallback.

What's the difference between.oga,.ogg, and.ogv?

Before 2007 everything Ogg used .ogg. RFC 5334 (Sept 2008) split the namespace: .ogv for video (video/ogg), .oga for audio (audio/ogg), and .ogx for multiplexed/application content (application/ogg). The legacy .ogg extension was preserved specifically for Vorbis-only audio for backwards compatibility with old hardware players. So a Vorbis file can validly be either .ogg or .oga, while a FLAC-in-Ogg or Opus-in-Ogg file should be .oga.

Why convert from WMV at all — can't I just play it?

You can on Windows with Windows Media Player or VLC, but WMV becomes painful elsewhere. macOS dropped native WMV support when Flip4Mac was discontinued; Linux distros need gstreamer1.0-plugins-ugly for the proprietary codecs; iOS/Android have no native WMV decoder; and most CMS and podcast platforms refuse to ingest WMV. Converting the audio to OGA (or WMV to MP3, WMV to WAV) gets you a universally playable file.

Can I trim the WMV before converting, so the OGA is just one section?

Yes. Expand Advanced Options, find Trim, and enter a start time and duration in HH:MM:SS.ms format (e.g. start 00:01:30.000, duration 00:00:45.000 to grab a 45-second clip starting 90 seconds in). The trim happens during encoding, so you get only the requested section in the OGA — no extra editor needed. For more granular cuts, the dedicated Audio Cutter lets you set waveform markers visually.

Is the conversion lossy if I pick FLAC?

The FLAC step itself is lossless, but the original WMV audio was almost certainly lossy WMA. Re-encoding a lossy WMA into FLAC produces a "lossless capture of a lossy source" — the FLAC file preserves every sample of the decoded WMA exactly, but it can't restore information WMA already threw away. FLAC inside OGA makes sense for archival when the source is uncompressed (WAV, AIFF) or already lossless; for a WMA-sourced WMV, Opus at 128 kbps gives you the same perceptual quality at roughly 8% the file size.

How big can my WMV upload be?

XConvert processes files on its servers and deletes them automatically after a few hours. For typical WMV recordings (lectures, screen captures, old camera footage at 1-4 Mbps total bitrate) that comfortably covers a multi-hour file. If you're hitting limits, convert to WMV to MP3 at a lower bitrate first, or batch-split the source in a desktop editor before uploading.
