How to convert MP3 to OGG
- Add your files: drag them into the box above, or click "Choose files".
- Click "Convert to OGG" and wait a few seconds while we process them.
- Download your OGG files. Uploaded files are deleted right away, and converted files are removed from our server after 30 minutes.
Why convert MP3 to OGG?
OGG (Ogg Vorbis) is an open, royalty-free audio format used a lot in games and web apps. Game engines such as Unity and Godot work well with OGG files, and many developers prefer it for sound effects and music. Converting MP3 to OGG gets your audio ready for those projects.
- You are adding music or sound effects to a game.
- A web app, open-source project or Linux tool expects OGG audio.
- You prefer an open, patent-free format for your audio library.
Will the OGG be smaller than my MP3?
Sometimes, but not always. Vorbis quality 5 is a variable setting, so the result depends on the sound rather than on the MP3 you start from. In our tests with four real MP3s, the OGG files averaged between 114 and 149 kbps.
That means the size change depends mostly on the bitrate of your MP3. Two songs saved at 192 kbps became 23% and 29% smaller. A 128 kbps track shrank by only 8%. A spoken recording at about 100 kbps actually grew by 11%, because quality 5 aims higher than that MP3 did.
If your only goal is a lighter file for a game build, the saving is real for typical music at 192 kbps or more. For low-bitrate MP3s, keeping them as MP3 may be the better choice when the project accepts both formats.
Details that matter when you import the files
- The audio inside the OGG is Vorbis, not Opus. Check that your engine or library expects Ogg Vorbis.
- Sample rate and channels are copied from the MP3: a 48 kHz stereo song stays 48 kHz stereo. If a sound effect has to be mono, change it in an audio editor.
- Title and artist tags are kept, stored the way Ogg files normally store them. The embedded cover picture is not carried over.
- Each file is converted separately and keeps its name, with only unusual symbols removed, so a batch of short effects stays easy to match with the originals.
Tips for the best result
- We encode Vorbis at quality 5 (about 115 to 150 kbps in our tests), which sounds very close to the MP3 source.
- Converting from MP3 (compressed) to OGG (compressed) cannot improve quality. If you have the original WAV, convert from that instead.
- OGG files are about the same size as MP3s at similar quality.
About these formats
MP3: The most popular audio format. It compresses sound to a small size while keeping good quality, and it plays on any device.
OGG: An open, royalty-free audio format (Ogg Vorbis). It is common in games, web apps and Linux software.
Frequently asked questions
Why do games use OGG?
It is royalty-free, well supported by game engines and loops cleanly, which makes it popular for music and effects.
Does OGG sound better than MP3?
At similar bitrates they sound very similar. Converting an MP3 to OGG will not make it sound better.
Can I play OGG on my phone?
Most Android phones and many apps play OGG. On iPhone, support depends on the app.
Is this OGG Vorbis or OGG Opus?
Ogg Vorbis, encoded at quality 5.
What bitrate does OGG quality 5 use?
It is variable. With our test files it averaged 114 to 149 kbps, depending on how complex the sound was.
Why did my OGG come out bigger than the MP3?
Your MP3 probably had a low bitrate, around 100 kbps or less. The OGG is encoded at a fixed quality level that can need more data than that. Keeping the MP3 is fine if it already sounds good enough.
