AAC to OGG Converter

AAC to OGG Converter

Turn your AAC file into an Ogg Vorbis (.ogg) file — a free, open format with small file sizes and wide support on Android, Linux, VLC, and most games and streaming apps. It's converted right on your own device, so the audio file itself is never sent anywhere.

Processed locally on your device — your file is never uploaded. Max file size: 100MB.

How It Works

1

Pick Your File

Select the AAC or M4A file you'd like to convert. It never leaves your device at any point in the process.

2

On-Device Encoding

Your browser decodes the AAC and re-encodes it as Ogg Vorbis using an open-source encoder — nothing is sent to a server. Longer files take a bit more time.

3

Save Your File

Download your new OGG file, ready for the apps and devices that use it.

Frequently Asked Questions

Yes, there's no limit on conversions and no signup required.

No. Conversion happens entirely in your browser; your file is never uploaded to a server.

Files are encoded at a variable bitrate roughly equivalent to 128–160kbps, a good balance of quality and file size.

OGG plays natively on Android, Linux, VLC, and most desktop browsers. Apple devices and some older software have limited or no built-in support, so check your player first if you're on iPhone or iPad.
