MPEG to OGG Converter

How to Convert MPEG to OGG Online

1. Upload Your MPEG Files: Drag and drop or click "+ Add Files" to select .mpg or .mpeg clips from your computer. Batch is supported — queue a season of recordings, lecture rips, or DVB captures and extract them in one pass.
2. Pick Compression Method and Quality Preset: Default codec is Vorbis. Choose Quality Preset (Lowest, Low, Medium, High, Very High, Highest) for the simplest path — High maps to roughly 160 kbps and is the sweet spot for music. Switch to Custom Bitrate for Constant or Variable Bitrate targets from 45 kbps up to 500 kbps, or Specific file size when you need to hit a fixed output size for a memory card or upload limit.
3. Set Audio Channel, Sample Rate, and Trim (Optional): Leave Audio Channel on Original to keep stereo (or force Mono to halve file size for spoken-word). Audio Sample Rate defaults to Original — drop to 22050 Hz or 16000 Hz for voice, keep 44100 Hz for music, or 48000 Hz to match broadcast/DVB sources. Use Trim with start time and duration in HH:MM:SS.mmm to extract a single song, chapter, or interview segment.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no queue. Each output downloads as a standalone .ogg you can drop straight into Unity, Godot, Audacity, or VLC.

Why Extract OGG from MPEG?

MPEG-1 and MPEG-2 video files (.mpg, .mpeg) typically carry MPEG-1 Audio Layer II (MP2) — a 1992 codec that's still standard in DVB television and DVD-Video but is a poor fit for modern audio workflows. Re-encoding to Ogg Vorbis gives you a royalty-free container that game engines, Linux audio stacks, and HTML5 browsers all read natively, usually at 15-20% smaller file size for comparable perceptual quality.

• Game audio assets — Unity imports .ogg natively and uses Vorbis as its default compressed audio format. Godot treats Ogg Vorbis as the primary music format and decodes it on every platform the engine targets. Unreal Engine accepts .ogg through its standard audio import pipeline.
• DVB recordings and DVR captures — TV tuner cards, set-top recorders, and over-the-air DVR software write MPEG-2 transport streams with MP2 audio. Extracting to Ogg gives you a player-friendly audio file for clips, podcasts, or archival.
• Linux and open-source audio — Vorbis is the historical default on GNU/Linux because, unlike MP3 (whose core patents expired in 2017) and AAC, Vorbis has been royalty-free since its May 2000 release. Audacity, mpv, Rhythmbox, and Banshee all open .ogg without extra codec packs.
• Web playback — Chrome, Firefox, Edge, and Opera all play Ogg Vorbis in HTML5 <audio> elements; only Safari requires a fallback. Vorbis is a viable alternative to MP3 for browser-based players that want a free format.
• VOIP and voice archives — Mono Vorbis at 64-80 kbps produces clean speech at roughly half the size of an MP3 at 128 kbps, which matters for hosting hour-long lectures or interviews.
• Smaller files than MP3 — At equivalent perceptual quality, Vorbis files are typically 15-20% smaller than MP3, useful for mobile distribution or sample libraries shipped with apps.

MPEG (MP2) vs OGG (Vorbis) — Format Comparison

Vorbis Quality Preset and Bitrate Guide

Vorbis is a variable-bitrate codec — quality presets map to a target average bitrate. Use this table to pick the right preset for the job.

For reference, Vorbis at q5 (~160 kbps) is widely regarded as transparent for most listeners and produces files about 15-20% smaller than MP3 at 192 kbps. The Xiph.Org Foundation has recommended Opus for new projects since February 2013, but Vorbis remains the right pick when your target platform (Unity, Godot, older Firefox, embedded players) expects .ogg with Vorbis inside.

Frequently Asked Questions

My MPEG file is a video — does this strip the picture and keep only the audio?

Yes. .mpg and .mpeg containers hold both video (MPEG-1 or MPEG-2 video) and audio (usually MPEG-1 Audio Layer II / MP2). This tool demuxes the audio stream and re-encodes it to Ogg Vorbis. The video track is discarded; you get a pure audio .ogg file. If you want to keep the video and just change containers, use one of our video conversion tools instead.

Why re-encode MP2 to Vorbis instead of just remuxing?

You can't put MP2 inside an Ogg container as a first-class stream — Ogg's mapped audio codecs are Vorbis, Opus, FLAC, and Speex. So extracting MP2 audio to .ogg always means a re-encode. To minimize generation loss, pick High or Very High preset (q5-q7) rather than a low-bitrate target.

Should I use Vorbis or Opus inside the OGG container?

For game engines (Unity, Godot) and existing Vorbis-only pipelines, stick with Vorbis. For new web projects, voice/VOIP, or anywhere bandwidth matters below 96 kbps, Opus is the better choice — Xiph.Org has recommended Opus over Vorbis since 2013. Opus is supported in all modern browsers including Safari, which Vorbis is not.

What bitrate matches the original MPEG audio?

DVB and DVD MPEG audio is typically MP2 at 192-256 kbps stereo. To preserve perceived quality without bloat, target Vorbis at q5-q7 (~160-224 kbps). Going above 256 kbps in Vorbis when the source is 192 kbps MP2 wastes space without recovering detail that the lossy MP2 encoder already removed.

Will this work for MPEG-2 video files (.mpg from DVDs)?

Yes — the tool accepts .mpg and .mpeg containers regardless of whether the video stream inside is MPEG-1 or MPEG-2. Audio in MPEG-2 program streams is most often MP2 (DVB) or AC-3 (DVD-Video, region-dependent); both are demuxed and re-encoded to Vorbis.

What's the difference between Constant Bitrate and Variable Bitrate?

Constant Bitrate (CBR) holds the bitrate steady across the whole file, which is easier for streaming or hardware that expects predictable data rates. Variable Bitrate (VBR) lets the encoder spend more bits on complex passages and fewer on silence or simple sections — it produces smaller files at the same perceived quality. Vorbis was designed VBR-first; pick CBR only when a target system requires it.

Can I extract just a chapter or song from a long MPEG capture?

Yes. Expand Trim, set the start time and duration in HH:MM:SS.mmm format. For finer or repeated edits after conversion, use the Audio Cutter on the .ogg output. If you want lossless cutting of an existing .ogg, that tool can split on packet boundaries without re-encoding.

What if I want MP3 instead of OGG, or I need to compress an existing OGG?

Use Convert MPEG to MP3 for MP3 output, or Convert OGG to MP3 to convert an .ogg you already have. To shrink an existing .ogg without changing codec, Compress OGG re-encodes at a lower quality preset. There's also a parallel Convert MPG to OGG page if your source file uses the .mpg extension. For audio extracted from .mp4 video, see Convert MP4 to OGG.

Is my file uploaded to a server?

Files are uploaded over HTTPS for processing and are deleted automatically after the session ends. No sign-up is required, there's no watermark, and there's no file count limit on a single batch.
