About converting OGG to MP3
OGG is a free, open audio format. Games, free music programs, Linux apps and many sound libraries save their audio as .ogg. It sounds good and the files are small.
The problem is that not every device plays it. Many car stereos, older music players, some phone apps and many websites do not accept OGG. MP3 works everywhere.
This tool turns an OGG file into an MP3. It runs in your browser, so the file is never uploaded.
Features
- OGG Vorbis and Opus — music, game sounds and voice notes in .ogg or .oga
- MP3 out — or M4A, WAV, FLAC or another OGG if you need one
- Pick the quality — 128 to 320 kbps; 192 kbps is set for you
- Short or long — a one-second game sound or an hour-long recording
- Listen first — play the OGG and the MP3 on the page
- Private — converted on your device, never uploaded
What is inside an OGG file?
OGG is a "box" that can hold different kinds of sound. This page reads all the common ones:
- Vorbis — the classic OGG sound for music, games and sound effects
- Opus — newer and very small; used for voice messages and calls. For WhatsApp and Telegram voice notes there is a page of its own: OPUS to MP3
- FLAC in OGG — rare, lossless; it converts the same way
You do not need to know which one you have. The converter finds out by itself.
Which MP3 bitrate for an OGG file?
OGG and MP3 both leave out detail to save space. Converting one to the other is a second round of that, so give the MP3 a bitrate a bit higher than the OGG had. Most OGG Vorbis files are made with a "quality" number. This table shows the usual bitrate for each number, and a good MP3 choice for it:
| OGG Vorbis quality | About this bitrate | Good MP3 choice |
|---|---|---|
| q3 | 112 kbps | 192 kbps |
| q4 | 128 kbps | 192 kbps |
| q5 | 160 kbps | 256 kbps |
| q6 | 192 kbps | 256 kbps |
| q8 | 256 kbps | 320 kbps |
| q9 or q10 | 320 kbps or more | 320 kbps |
The bitrates are the usual values for stereo music at 44.1 kHz. A voice recording or an Opus voice note is fine at 128 kbps.
How big will the MP3 be?
An MP3's size is bitrate × length ÷ 8, so you can work it out before you convert:
| Length | 128 kbps | 192 kbps | 256 kbps | 320 kbps |
|---|---|---|---|---|
| 30 seconds (a game sound) | 0.48 MB | 0.72 MB | 0.96 MB | 1.2 MB |
| 3 minutes (a song) | 2.88 MB | 4.32 MB | 5.76 MB | 7.2 MB |
| 10 minutes | 9.6 MB | 14.4 MB | 19.2 MB | 24 MB |
| 60 minutes | 57.6 MB | 86.4 MB | 115.2 MB | 144 MB |
1 MB = 1,000,000 bytes. The MP3 is often a little bigger than the OGG was, because OGG Vorbis packs sound a bit better than MP3 at the same quality.
What people use it for
- Playing game music or sound effects in a normal music player or a video
- Using a sound from a free sound library in an editor that only takes MP3
- Opening a recording made with free or Linux software on a phone or in a car
- Putting OGG music on a USB stick for a car stereo or a TV
- Sending an OGG file to someone who cannot open it
Good to know
- Only convert sounds and music you are allowed to use. Converting does not change who owns them.
- The title and artist tags inside an OGG file are not copied to the MP3. Add them with the MP3 Tag Editor.
- This page converts one file at a time. For many OGG files, use the Bulk Audio Converter.
- The first conversion downloads the converter (about 30 MB) once. After that it starts at once.
- To keep only a short part of the sound, cut the MP3 with the MP3 Cutter.
Frequently asked questions
Is OGG better than MP3?
At the same file size, OGG Vorbis usually sounds a little better than MP3. But MP3 plays on far more devices. That is why people convert OGG to MP3: not for better sound, but so it plays everywhere.
Will the MP3 sound worse than the OGG?
At a bitrate a step above the OGG's, like 192 kbps for a normal OGG file, almost nobody can hear a difference. Converting can never make the sound better than the OGG was.
Why does my phone not play OGG files?
Some phones, apps, car stereos and players simply do not include OGG. An MP3 of the same sound plays on all of them.
Is my file uploaded?
No. The conversion runs on your own device, inside this page. The file never reaches a server.
