M4A (.m4a) · Max 20 MB
M4A 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 M4A 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 quality similar to M4A?
Both are lossy formats with good quality. At comparable bitrates, OGG Vorbis and AAC (used in M4A) perform similarly. Converting between them may introduce minimal quality loss.
Where is OGG commonly used?
Linux systems, game engines (Unity, Godot, Unreal), web applications, Spotify's internal format, and open-source media players all use OGG Vorbis.
Can I play OGG files on my phone?
Android supports OGG natively. On iPhone, you'll need a third-party player like VLC. For Apple devices, M4A is the better format.

Apple's preferred audio format. Better quality than MP3 at same bitrate. Default for iTunes and Apple devices.
About OGG
Open-source compressed format. Better quality than MP3 at similar bitrates. Used in gaming and web applications.
