MPG to OGA Converter

Extract Audio from MPG to OGA Online

This tool pulls the soundtrack out of an MPG video and saves it as an OGA file — the audio-only flavour of the Ogg container. The video frames are discarded; only the audio is kept. An MPG (an MPEG-1 or MPEG-2 program stream, first standardised in 1993) almost always stores its audio as MP2, so the conversion re-encodes that to Vorbis inside Ogg — an open, royalty-free format that plays natively in Firefox, Chrome, Edge, and Safari 18.4+. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark.

How to Convert MPG to OGA

1. Upload Your MPG File: Drag and drop your MPG onto the page, or click "+ Add Files" to browse. The .mpeg extension works the same way, and you can queue several clips to convert with the same settings.
2. Set the Quality Preset or Bitrate: Open Advanced Options. The output codec is Vorbis. Leave Quality Preset at Highest, or switch to Custom Bitrate / Constant Bitrate (for example 128, 192, or 256 kbps) for an exact rate. Specific file size lets you target an output size in MB.
3. Adjust Channels, Sample Rate, or Trim (Optional): Audio Channel and Audio Sample Rate default to ORIGINAL (matched to the source). Set them to mono or a lower rate for speech, or use Trim to keep only a start time and duration.
4. Convert and Download: Click "Convert" and save your OGA file. No sign-up, no watermark.

MP2 to Vorbis — What to Expect

MPG audio is typically MP2 (MPEG-1 Audio Layer II), which is already lossy. Re-encoding it to Vorbis is a lossy-to-lossy transcode, so there is no way to recover detail the MP2 step discarded, and a small amount of extra generational loss is normal. Keeping the Quality Preset at Highest, or choosing a bitrate at or above the source's, keeps that loss inaudible in most cases.

Frequently Asked Questions

Will I lose quality converting MPG audio to OGA?

The audio inside an MPG is almost always MP2, which is already a lossy format, so re-encoding it to Vorbis stacks a second lossy step on top — there is no quality to "regain," only a little more to potentially lose. In our testing, a Vorbis output at the Highest preset (roughly 192-256 kbps) kept the result transparent against the MP2 source even on headphones. Dropping below ~96 kbps is where dense music starts to show artifacts.

What happens if my MPG has no audio track?

If the source MPG is video-only with no audio elementary stream, there is nothing to extract and the resulting OGA would be empty. Check the original file in a player like VLC first; if it has no sound, this conversion has no audio to pull out.

Is OGA the same as OGG?

They are the same Ogg container with different extensions. Xiph.Org registers .oga for audio-only files and .ogg for general Ogg use, both under the audio/ogg MIME type, so the audio bytes are identical — only the extension and OS hint differ. If you specifically need the .ogg extension, use our MPG to OGG converter instead.

Which browsers and players support OGA out of the box?

Ogg Vorbis audio plays natively in Chrome, Firefox, Edge, and Safari 18.4 and later, reaching about 95% of browsers globally per caniuse. Apple devices had no native Ogg support before Safari 18.4 / iOS 18.4, so older iPhones and iTunes will refuse the file. Open-source players like VLC and Audacity handle OGA on every platform.

Should I convert to OGA or MP3 from my MPG?

Choose OGA when you want a royalty-free file for the web, game engines (Unity, Godot, and Unreal import Ogg Vorbis natively), Linux desktops, or Wikimedia uploads. Choose MP3 when you need the widest possible device compatibility, including older hardware and Apple products that predate Safari 18.4 — in that case use our MPG to MP3 converter.

Can I extract just one section of the MPG?

Yes. Use the Trim controls in Advanced Options to set a start time and a duration. Both fields accept seconds (for example 12.5) or HH:MM:SS.sss (00:01:30.500), which is handy for pulling a single song or a quote out of a long recording.
