Compress MP3 to OGG
Need smaller audio files? Converting MP3 to OGG dramatically reduces file size. A 50MB file becomes 5MB. Perfect for email, sharing, and storage.

MP3 (.mp3) · Max 20 MB
MP3 files are already compressed, but OGG can compress further at a different bitrate. The size reduction is significant for sharing, uploading, and storage.
For email attachments, 128-192kbps works well. For music sharing, use 256-320kbps. AudioUtils lets you drop your file and convert instantly. No upload to a server, no waiting.
Both MP3 and OGG are lossy formats. Each re-encode can degrade quality slightly. Convert once and keep the result. Choose the right bitrate for your use case. Higher bitrate means better quality but larger files.
Frequently Asked Questions
Is OGG better than MP3?
In terms of audio quality per bitrate, yes. OGG Vorbis at 128kbps sounds roughly equivalent to MP3 at 160-192kbps. It's also completely open-source and patent-free.
What apps support OGG?
Most modern media players (VLC, foobar2000), web browsers (Chrome, Firefox, Edge), game engines (Unity, Unreal, Godot), and audio editors (Audacity). Apple devices need a third-party app.
Can I play OGG files on iPhone?
Not natively. iOS doesn't support OGG out of the box. You'll need a third-party player like VLC for iOS, or convert to M4A/MP3 instead.
Is the conversion lossless?
No. Both MP3 and OGG are lossy formats. Converting between them involves re-encoding, which can introduce a slight quality loss. For best results, convert from a lossless source like WAV or FLAC.
