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

OGG (.ogg) · Max 20 MB
OGG files are already compressed, but MP3 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 OGG and MP3 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
Why won't my OGG file play on iPhone or Mac?
iOS and macOS don't support OGG natively. The stock Music app, QuickTime, and AirPlay all reject OGG files. Converting to MP3 makes the file playable on any Apple device without installing additional software.
What bitrate should I use for the MP3?
Match or exceed the source OGG bitrate. If the OGG is 192 kbps, encode to at least 256 kbps MP3. For music, 320 kbps is near-transparent. For speech and podcasts, 128–192 kbps is fine. Going lower than the source bitrate compounds the quality loss from two rounds of lossy encoding.
Will I lose audio quality converting OGG to MP3?
A small amount, yes — both formats are lossy, and transcoding between them introduces a second round of encoding loss. At 256–320 kbps MP3 the difference is inaudible to most listeners on most hardware. For audiophile material, convert from a lossless source (WAV or FLAC) instead of OGG→MP3.
Is OGG better quality than MP3?
At the same bitrate, OGG Vorbis generally sounds slightly better than MP3 — it's a more efficient codec. But MP3 has near-universal hardware and software support, which almost always matters more in practice.
Can I convert game audio OGG files?
Yes. Game engines like Unity, Unreal, and Godot distribute audio as OGG. Extracted game audio rips are standard OGG Vorbis files and convert cleanly to MP3. Works with audio from most game engines, not just the three listed.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using FFmpeg compiled to WebAssembly. Your OGG file never leaves your device — we don't see it, store it, or log it.
