MPG to WEBA Converter

Extract WEBA Audio from MPG Online

This tool pulls the soundtrack out of an MPG video and saves it as a WEBA file — the audio-only flavour of Google's WebM container, carrying an Opus stream by default. 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 this conversion re-encodes that to Opus inside WebM — a small, modern audio file built for HTML5 <audio> and the Chrome/YouTube web pipeline. 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 WEBA

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 Opus inside WebM. Leave Quality Preset on Highest for a clean rip, or switch to Custom Bitrate / Constant Bitrate to lock an exact rate — 24–32 kbps is enough for speech, 96–128 kbps is transparent for music. 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 voice, or use Trim to keep only a start time and duration.
4. Convert and Download: Click "Convert" and save your .weba file. No sign-up, no watermark.

MPG vs WEBA — What Changes

Frequently Asked Questions

Will I lose quality converting MPG audio to WEBA?

The audio inside an MPG is almost always MP2 (MPEG-1 Audio Layer II), which is already a lossy format, so re-encoding it to Opus stacks a second lossy step on top — there is no quality to "regain," only a little more to potentially lose. In our testing, an Opus output at the Highest preset (roughly 128–160 kbps) stayed transparent against the MP2 source even on headphones, since Opus is markedly more efficient than the original MP2. Dropping below ~64 kbps is where dense music starts to show artifacts. The rule that keeps loss inaudible: match or exceed the source track's bitrate.

Does this output Opus or Vorbis inside the WEBA?

Opus by default. The audio-only WebM container can carry either Opus or Vorbis, and Opus is the modern choice because it beats Vorbis at every bitrate from about 6 kbps upward. If you specifically need Vorbis for an older WebM toolchain you can select it under Audio Codec in Advanced Options, but for almost every use, leave it on Opus.

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 WEBA 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 — and you may want a frame-grab or video conversion instead.

Will the WEBA play on iPhone and in Safari?

Treat it as not guaranteed on Apple. WebM container support arrived late on Apple platforms — desktop Safari 16 and iOS Safari 17.4 — and Opus-in-WebM playback has historically been patchy there. Chrome, Firefox, Edge, and Opera play WEBA without issues on every platform, reaching about 96% of browsers globally per caniuse, and VLC handles it everywhere. If your audience leans heavily Apple or you need a file that plays on legacy hardware and iTunes, extract to MPG to MP3 instead — MP3 plays on essentially every device made in the last 25 years.

How is this different from MPG to Opus or MPG to OGG?

It is the same Opus audio in a different wrapper. MPG to Opus gives you a raw .opus file that general-purpose audio players and Discord prefer; WEBA puts that Opus stream inside the WebM container that browsers and the YouTube/Chrome ecosystem expect for <audio> elements. MPG to OGG instead outputs Vorbis in an Ogg container, the older open-codec target Opus was designed to succeed. Pick WEBA for web embedding, .opus for standalone playback, and OGG when an older Ogg toolchain needs Vorbis.

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 quote out of a long recording. To slice a clip after conversion, the Audio Cutter edits the WEBA directly, and WEBA to FLAC rewraps it losslessly if you later need a lossless container.
