Convert MPEG to MP3
Pull the sound out of your MPEG and keep it as an MP3, leaving the picture behind. MP3 plays on absolutely everything, from a car stereo to a phone to a twenty year old player in a drawer. The practical difference is that the result opens anywhere, which MPEG files do not. Your file never leaves your computer.
How to convert MPEG to MP3
- 1 Drop your MPEG .mpeg or .mpg or .mpe file onto the page, or click to browse for it.
- 2 Choose the sound quality, or lift the existing track out untouched where that is possible.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the MP3, or add more files and do the whole set in one go.
Why convert MPEG to MP3
- An MPEG will not open in a browser, so anything going onto a web page, into a document or into a message has to become an MP3 first.
- You only want the sound: a lecture, an interview, a podcast that was filmed, or a track to listen to with the screen off.
- Plays on every device, browser and stereo ever built.
- All relevant patents have expired, so it is free to use.
- Audio attachments that must open anywhere.
MPEG compared with MP3
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | MPEG | MP3 |
|---|---|---|
| File extension | .mpeg | .mp3 |
| Browser support | No browser support | Every browser |
| Developed by | ISO/IEC MPEG | Fraunhofer IIS |
Quality and what changes
Whether anything is lost depends on the codec. If the track already matches the target, it can be copied out untouched and the audio is bit for bit what was in the MPEG. Choosing a different codec means decoding and re-encoding, which is a second generation of lossy compression on top of whatever the video already applied. Encoding at 192 kbps or above keeps that second generation inaudible for most material.
- One MP3 limitation to keep in mind: no surround sound in practice, and no perfect-copy mode.
Questions about MPEG to MP3
Will converting MPEG to MP3 lose quality?
A little. Both formats are lossy, so the file is decoded and compressed a second time and the two sets of artefacts add up. At a high quality setting the difference is hard to see, but avoid repeated round trips between lossy formats.
Does extracting the audio re-encode it?
Only when the target codec differs from the one in the MPEG. Where they match, the track is copied and the result is identical to the audio inside the video. Converting to a different codec means one extra generation of lossy compression.
Is my MPEG file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your MPEG is read straight from your own disk, converted on your machine and handed back as an MP3. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several MPEG files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate MP3 downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
