Convert OGG to MP3
OGG is a fine format that almost nothing outside of games and Linux ever played. This converts it to MP3, which plays on everything.

MP3 is lossy, so this is a size-versus-quality trade. 192 kbps is transparent to most listeners on most material.

Output quality
The Vorbis stream is decoded and re-encoded once with LAME at the bitrate you pick, preserving sample rate, channel layout and exact duration. Because both formats are lossy, this is generational loss and the usual advice applies: match or exceed the source bitrate to keep the second encode from becoming audible. OGG files are commonly encoded around 160 to 192 kbps, so 192 or 256 kbps is the safe choice here — going lower is where you would start to hear the two lossy stages stacking up, particularly on cymbals and other high-frequency detail.

Common use cases
Game audio and mods
OGG is the default in a lot of game engines; MP3 is what everything else plays.
Files downloaded from Wikipedia or open archives
Both prefer patent-free formats that consumer hardware never adopted.
Getting audio onto a car stereo
Almost none support OGG.
Sending audio to someone on Windows
MP3 avoids the "no app can open this" conversation entirely.
Settings you can change
Quality
320 kbps — highest, biggest file · 256 kbps — very good · 192 kbps — the usual choice · 128 kbps — small, fine for speech · 96 kbps — voice notes only
MP3 is lossy, so this is a size-versus-quality trade. 192 kbps is transparent to most listeners on most material.
Troubleshooting
- My file is refused
- The .ogg extension is also used for OGG containers holding video (Theora) or Opus audio. Only Vorbis audio is accepted here.
- The result sounds thinner than the original
- Raise the bitrate to 256 kbps. Two lossy stages at a low bitrate is where artefacts become audible.
- The MP3 is bigger than the OGG
- Expected — OGG Vorbis is more efficient than MP3 at the same quality. Lower the bitrate if size matters more than fidelity.

Privacy and file deletion
- Stored under a random nameUploads have no connection to the file name you sent and are never served from a public directory. This tool accepts files up to 200 MB, several at a time.
- Deleted on a timerUploads are removed within 2 hours and finished results within 24 hours, whichever comes first.
- Nobody looks at themNo one browses uploads, nothing is shared with third parties, and no file is used to train anything. The only thing kept past deletion is the size and timing of the job.
- Encrypted in transitEvery request runs over HTTPS, so the file is encrypted between your device and our server.

Frequently asked questions
Browse video toolsWhy will nothing play my OGG file?
OGG Vorbis is open and patent-free, which is why it was popular in games, on Wikipedia and across Linux. It never reached mainstream hardware, so car stereos, older phones and many TVs simply have no decoder for it.
Does it lose quality?
Slightly, because both formats are lossy and this is a second encode. At 192 kbps and above the difference is inaudible on normal equipment. Keep the OGG if you may need to re-convert.
Is my file uploaded?
Yes — decoding OGG and encoding MP3 needs FFmpeg. Stored under a random name, never listened to, deleted within 24 hours.
How long does my video stay on your server?
Your upload and the finished file are both deleted 24 hours after the job starts. This tool accepts files up to 200 mb and 60 minutes long. Nothing is shared with anyone and there is no account for it to be attached to; while a job is live we may open it in our own admin area to check the encode came out clean.
