Video to OGA Converter

How to Convert Video to OGA Online

1. Upload Your Video File: Drag and drop, or click "+ Add Files" to pick from your device. MP4, MKV, MOV, WebM, AVI, FLV, MTS, 3GP and 30+ other video formats are accepted. Batch uploads work — every file uses the same settings.
2. Pick the Audio Codec via Quality Preset: The default "Highest" preset writes Vorbis at roughly 320 kbps stereo, which matches what most desktop and Linux players expect inside a .oga container. Drop to "Medium" for podcasts and voice (~96–128 kbps) or "Lowest" for archival speech tracks where size matters more than fidelity.
3. Tune Audio Sample Rate, Channel, Bitrate or Trim (Optional): Keep "Original" sample rate to preserve the source, or force 48 kHz / 44.1 kHz to match a target DAW. Switch the channel to Mono to halve file size for spoken word. Use Custom Bitrate (CBR or VBR) when you need a specific number, Specific file size when you have a hard upload cap, or Trim to extract a single segment.
4. Convert and Download: Click "Convert" — files are processed on our servers and held in your private session, with no watermarks, no account, and no marketing emails. Download individually or grab everything as a ZIP.

Why Convert Video to OGA?

OGA is the Xiph.Org Foundation's recommended file extension for audio-only Ogg streams, standardized in 2007 alongside .ogv (video) and .ogx (multiplexed). The .oga extension can carry Vorbis, Opus, FLAC, Speex, or OggPCM payloads — that flexibility is the main reason Linux desktops, GStreamer-based players, and some HTML5 audio pipelines prefer it over the more codec-specific .ogg. Pulling the audio out of a video into an OGA gives you a smaller, easier-to-share file and removes any dependency on a particular video codec.

• Linux media library — GNOME Music, Rhythmbox, Clementine, and Strawberry index .oga natively without requiring proprietary codecs. Stripping a 1.2 GB MKV concert recording down to a 90 MB Vorbis OGA makes it usable on a netbook or a Raspberry Pi without the player ever spinning up a video decoder.
• Open-source podcast pipelines — Tools like Auphonic and Castopod accept Ogg/Vorbis sources, and many Fediverse audio hosts prefer royalty-free codecs. Converting a Zoom recording or an OBS capture to OGA keeps the workflow patent-free end to end.
• Web audio embeds — Firefox and Chromium have shipped Vorbis-in-Ogg playback for over a decade, and the W3C HTML spec lists audio/ogg as a recommended fallback. Use OGA alongside an AAC/MP3 source in a <audio> tag so Linux Firefox users get a non-proprietary stream.
• Game audio assets — Godot, Unity (via plugins), and most indie engines load Vorbis OGA directly because the codec is license-free and decodes cheaply on mobile CPUs. Converting cutscene videos to OGA gives you ready-to-import voice and music tracks.
• Speech archives — Pair OGA with the Speex or Opus codec (selected via the "Custom Bitrate" / codec dropdown) for an archive of lectures, interviews, or oral history recordings at one-third the size of MP3 with no royalty exposure.
• Removing video to save quota — Cloud backups, email attachments (Gmail caps at 25 MB, Outlook.com at 20 MB for free accounts), and Discord's 10 MB free upload limit are easier to live with when you've discarded the video track entirely.

OGA vs OGG vs MP3 — Format Comparison

Audio Codec & Quality Preset Guide

Vorbis is the default codec because it is the most broadly supported payload inside a .oga container. To switch to FLAC (lossless), Opus (best efficiency below 64 kbps), or Speex (legacy VoIP), open Custom Bitrate and use the codec dropdown.

Frequently Asked Questions

Will iPhone or QuickTime play the OGA file I get?

Not by default. Apple has never shipped native Ogg/Vorbis decoding in iOS, macOS QuickTime, or the Music app. You will need VLC, Outline Music, Doppler, or another third-party player. If iPhone playback is the goal, convert to MP3 or M4A instead — both decode in stock Apple software. OGA is the right choice when the destination is Linux, Android, Firefox, Chrome, or a game engine.

What is the difference between picking .oga and .ogg here?

The bytes inside the file can be identical — both are Ogg containers — but the extension signals intent. Xiph.Org recommended in 2007 that .oga be used for audio-only streams and .ogg be reserved for Ogg Vorbis specifically (or kept as a generic Ogg label). Some Linux media scanners, GStreamer plugin chains, and audio-only players treat .oga as a hint to skip video-codec probing. If you are unsure, .oga is the safer modern choice for audio extracts; convert to .ogg instead when a particular tool insists on it.

Why is my OGA larger than I expected after extracting from a small video?

The video file's size was dominated by H.264 or HEVC video at maybe 2–8 Mbps, while the audio track was typically 128–384 kbps. Extracting at the "Highest" preset re-encodes to Vorbis at 320 kbps, which is close to the original audio bitrate. To make the OGA significantly smaller, drop to Medium (128 kbps) or switch the channel layout to Mono — for a one-hour clip that is the difference between ~140 MB and ~30 MB.

Will the conversion lose audio quality?

It is a lossy-to-lossy transcode unless your source was lossless (uncommon in video). Vorbis at 192 kbps and above is generally considered transparent for music in blind listening tests, but each generation of lossy encoding compounds artifacts. If you plan to edit further, choose FLAC via the Custom Bitrate panel to write a lossless OGA, then encode to lossy later. If the source was already MP3 audio inside an MKV, expect very mild additional artifacts — use Medium or higher to keep them inaudible.

Can I extract a single section instead of the whole video?

Yes. Open "Trim" in Advanced Options, set the start time in HH:MM:SS.mmm, and either set an end time or a duration. Only the chosen segment is encoded, so the OGA is exactly the length you specified. For multi-segment cuts (intro, two highlights, outro), convert the whole video first and then use the audio cutter on the resulting OGA.

Does this work for huge files like a 4-hour MTS camcorder clip or a 4K MKV?

Yes — the upload and conversion run on our servers, not in your tab, so memory is not capped by your browser. Long files are still bandwidth-bound on your upload, and very large videos may take several minutes to upload before encoding starts. If you only need part of the audio, the Trim option avoids re-encoding the entire track.

What sample rate should I pick when the destination is Linux audio editing?

Match the source. Most video files carry 48 kHz audio (the broadcast and consumer-camera standard), while music-focused sources are often 44.1 kHz (CD lineage). Setting "Original" keeps the source rate untouched. Force 48 kHz only when your destination DAW or video editor is locked to that rate — resampling 44.1 → 48 introduces minor phase artifacts and is rarely worth it for an audio extract.

Is OGA still relevant in 2026 with Opus and AAC widely available?

Yes, for two reasons. First, .oga is the canonical extension for any audio-only Ogg payload, and Opus-in-Ogg is increasingly common (especially for podcasts and WebRTC archives) — a .oga file can already be carrying Opus. Second, royalty-free playback matters for open-source projects, public broadcasters in jurisdictions that avoid AAC licensing, and game developers shipping on Linux. AAC is more efficient on iOS, but OGA remains the friendlier format for the open-source ecosystem.
