How to Convert MP4 to OGG
Upload
Drag and drop your MP4 video file into the converter above, or click Choose Video File to browse your device.
Extract & Convert
Click Convert to OGG. Our server extracts the audio track from your video and encodes it as OGG Vorbis. Takes a few seconds to a couple of minutes.
Download
Click Download OGG to save the extracted audio file. That's it — no registration, no email required.
Extract Audio from MP4 on Any Device
On Windows
Upload your MP4 video from any Windows device and get OGG audio back in seconds. Windows does not natively play OGG files in Windows Media Player, but VLC, foobar2000, and all major browsers handle OGG Vorbis perfectly. Game developers on Windows can import the extracted OGG files directly into Unity, Unreal Engine, or Godot without any additional conversion steps.
On Mac
Our converter works in Safari, Chrome, and Firefox on macOS. While macOS default apps (Finder, QuickTime, Music) cannot play OGG files, Safari 17+ supports OGG Vorbis playback natively in the browser. For local playback, VLC for Mac and IINA handle OGG without issues. This is an easy way to extract audio from iPhone-recorded videos and convert to OGG for cross-platform use.
On Linux
OGG Vorbis is the native audio format on Linux — every major desktop environment plays OGG files out of the box with no additional codecs. Upload your MP4 video from any Linux browser, and the extracted OGG audio will play immediately in your default media player. Linux distributions have historically preferred OGG over MP3 due to its open-source, patent-free nature.
On Mobile
Works on both Android and iOS. Android has built-in OGG Vorbis support since its earliest versions, so extracted audio plays natively. On iOS, Safari 17+ supports OGG playback in the browser. This is especially useful for extracting audio from videos recorded on your phone — pull the sound from a concert recording, interview, or lecture and save it as a lightweight OGG file.
What is MP4?
MP4 (MPEG-4 Part 14) is a multimedia container format that can hold video, audio, subtitles, and still images in a single file. Developed by the ISO as part of the MPEG-4 standard, it became the dominant video format on the internet, used by YouTube, streaming services, smartphones, and virtually all video editing software.
The MP4 container typically holds H.264 or H.265 video with AAC audio, though it can contain many different codecs. The audio track inside an MP4 is usually high-quality AAC at 128–256 kbps. When you convert MP4 to OGG, the video track is discarded and only the audio is extracted and re-encoded as OGG Vorbis.
MP4 is essentially a video container, not an audio format. If you only need the audio from a video — for a podcast, music library, game asset, or web page — extracting it as OGG produces a much smaller file (audio-only) while preserving the sound quality.
What is OGG?
OGG Vorbis is an open-source, royalty-free lossy audio codec developed by the Xiph.Org Foundation. Released in 2000 as a free alternative to proprietary audio formats, OGG uses the Ogg container format with the Vorbis audio codec. The entire technology stack — container, codec, and tools — is completely patent-free and licensed under BSD/LGPL.
Vorbis uses a modified discrete cosine transform (MDCT) with variable bitrate (VBR) encoding by default. This means the encoder dynamically allocates more bits to complex audio passages and fewer to simple ones, producing better quality per byte compared to constant-bitrate codecs. At 128 kbps, OGG Vorbis consistently outperforms MP3 in blind listening tests.
OGG Vorbis is the standard audio format for gaming (Unity, Unreal Engine, Godot, SDL), Linux desktops, and open-source software. It's supported by all major web browsers for HTML5 audio. The trade-off is limited support on Apple devices (no iTunes/Music support) and some older hardware players.
MP4 vs OGG: Quick Comparison
| Feature | MP4 | OGG Vorbis |
|---|---|---|
| Type | Multimedia container (video + audio) | Audio-only format |
| Standard | MPEG-4 Part 14 (ISO/IEC 14496-14) | Xiph.Org Vorbis I (2000) |
| Audio codec | Usually AAC (can vary) | Vorbis (MDCT-based) |
| Contains video | Yes (H.264, H.265, etc.) | No (audio only) |
| Typical file size | Large (video data dominates) | Small (audio only) |
| License | Proprietary codecs (H.264/AAC) | Open source (BSD/LGPL) |
| Browser support | All browsers | Chrome, Firefox, Edge, Opera, Safari 17+ |
| Game engine support | Video playback only | Standard audio format (Unity, Unreal, Godot) |
| Linux support | Requires codecs on some distros | Native, preinstalled |
| Best for | Video content, streaming | Game audio, web audio, podcasts, Linux |
Why Extract Audio from MP4 as OGG?
Game audio assets
Game developers frequently source audio from video recordings — foley sound, voice acting sessions, ambient recordings, and music videos. Extracting the audio track as OGG gives you production-ready game assets without intermediate steps. OGG Vorbis is the standard for Unity, Unreal Engine, and Godot because it's royalty-free, efficient, and decodes with low latency during gameplay.
Web audio & HTML5
Need audio for your website but only have video files? Extract the audio track and serve it as a lightweight OGG file instead of embedding the full MP4 video. This dramatically reduces bandwidth — an OGG audio file is typically 90–95% smaller than the source MP4 video. All modern browsers support OGG through the HTML5 <audio> element.
Podcast & lecture extraction
Many podcasts, lectures, and interviews are recorded as video but consumed as audio. Convert the MP4 recording to OGG to create an audio-only version that's easier to distribute, takes less storage, and works on audio-focused platforms. OGG's variable bitrate encoding ensures speech content is compressed efficiently while preserving clarity.
Music from video recordings
If you recorded a live performance, rehearsal, or studio session on video, you can extract just the audio as OGG for your music library. The extracted OGG file preserves the full audio quality from the original video while discarding the video data you don't need — resulting in a file that's a fraction of the original size.
