Should you convert MP3 to OGG?
A game engine, open-source app or Android project wants royalty-free Ogg Vorbis audio.
Fine when a player or app needs OGG. Converting between two lossy formats compresses the sound a second time, so match or exceed the original bitrate to keep the loss inaudible.
MP3 is the most compatible lossy audio format ever made; OGG is open-source lossy audio, common in games and on Android. Use OGG for game engines, Android apps and open-source projects that prefer free formats.
How to convert MP3 to OGG
- 01
Add your MP3
Drop your MP3 file onto the box, or click to choose it. It is read from your disk and stays there.
- 02
Check the settings
The output is already set to OGG. Change the bitrate if you want to; the defaults suit most files.
- 03
Save the OGG
Press convert and save the OGG. Several files come back together as a ZIP.
What changes when MP3 becomes OGG
Two rounds of compression
Each lossy encode throws away a little more. A MP3 at 128 kbps converted to OGG at 192 kbps sounds like the original; converted at 96 kbps it can turn swirly and dull.
The size stays about the same
MP3 and OGG are close in size for the same content, so do this for compatibility rather than to save space. MP3: About 1 MB a minute at 128 kbps, 2.4 MB at 320 kbps. OGG: Similar to or slightly smaller than MP3.

Why it doesn’t upload
Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.
How to check for yourselfWorth knowing
- About the MP3. Converting a low-bitrate MP3 to 320 kbps makes it bigger without making it sound any better; what was thrown away is gone.
- About the OGG. The .ogg extension can hold Vorbis, Opus or FLAC audio, so one OGG plays in a player and the next doesn’t.
- MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.
Questions
Does converting MP3 to OGG lose quality?
OGG is lossy, so a little is discarded, but at the default bitrate the difference is inaudible for nearly everyone.
Will an OGG play in my car or on my phone?
OGG has patchy support: Android, Chrome, Firefox and VLC, but not every Apple app, car stereo or editor.
