Convert OGG to MP3
Convert OGG to MP3 on your device. Choose your file, convert, and check the result before sharing.
Drop the ogg file
Drag your OGG onto the page or click to browse. It is read locally, never sent anywhere.
Choose MP3 and bitrate
Pick 128, 192, 256 or 320 kbps. 192 kbps is the default. Click Convert to start processing in this tab.
Save the mp3
The finished MP3 downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Your ogg file is decoded and re-encoded by code in this tab - a song, a memo, a podcast never leaves the device.
Local conversion
No upload time for a big ogg file, no server queue, no waiting on a download link.
No account, no daily cap
No daily caps, no "3 conversions left", no email wall. Convert the whole ogg library.
The two formats, briefly
| OGG | OGG is a container. This converter writes Vorbis audio at a fixed quality setting, not Opus. | |
|---|---|---|
| MP3 | MP3 is a lossy audio format. This converter encodes it at the selected bitrate rather than copying the original audio stream. | |
When you need this
- Use MP3 when your receiving app or player does not accept OGG. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
Tested on a sample file
On 26 October 2026 we converted a synthetic 90-second stereo OGG Vorbis file (1.1 MB, about 100 kbps, 44.1 kHz; tones and noise, not music) to MP3 at the default 192 kbps in Chrome on a Linux server, not a laptop or phone. The result was a 2.1 MB MP3 of the same length, about 1.9 times the size of the OGG. It took about 2 seconds once the converter had loaded.
The OGG was smaller because it used a lower bitrate than the MP3 setting. A higher MP3 bitrate makes the file larger and cannot bring back detail Vorbis already removed. The 128 kbps option gave a 1.4 MB MP3 for this file.
We decoded each MP3 from start to end with no errors. We did not listen to them. Not tested: phones, Safari, real music recordings, long files.
OGG vs MP3: what changes
| OGG | MP3 | |

| Kind | Audio | Audio |
| Compression | Vorbis audio output here | Lossy audio |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |
| Opens on | Check the source in your app and browser. | Check the downloaded file in the receiving app. |
| Best for | Keep the original as your source. | MP3 workflows, subject to the limits below. |
Keep the original. Compare the exported file before sharing or replacing it.
Tested on this tool
On 3 November 2026 we ran a synthetic test file through this converter: an 8-second OGG Vorbis tone (16 KB). The output was a 189 KB MP3 at about 192 kbps, 44.1 kHz, 8.05 seconds - and the downloaded file decoded cleanly when we checked it.
- The output was twelve times larger than the source in this test: a pure tone compresses extremely well in Vorbis, while the MP3 is written at a steady bitrate. Real music will not grow that much, but a lossy-to-lossy conversion can still produce a bigger file than the source.
- Converting cannot add quality. The MP3 sounds like the OGG, not better.
One small synthetic file is not every OGG. Opus-encoded OGG files were not part of this test.
Good to know
- The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
