Compress AAC to OGG

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

AAC (.aac) · Max 20 MB

AAC 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.

Sizes are comparable: AAC and OGG both sit near 1.2–1.2 MB per stereo minute, so this conversion is about compatibility, not storage. You're stacking a second lossy generation. At a generous bitrate that's inaudible, but if you still have a lossless original, encode from that instead: one generation always beats two.

Most people meet AAC through HLS streaming segments. It is a fine format there; the trouble is that a bare .aac stream lacks the container index that tells software its duration, so players won't list it and editors import it wrong. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. Disk usage barely moves — this conversion buys compatibility rather than space. Both AAC and OGG are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the AAC exists, encode the OGG from that instead.

Frequently Asked Questions

How much smaller will the file get?

Sizes are comparable: AAC and OGG both sit near 1.2–1.2 MB per stereo minute, so this conversion is about compatibility, not storage.

What bitrate keeps the quality acceptable?

192–256 kbps is transparent for most music, 128 kbps is fine for speech, and 64–96 kbps mono is plenty for pure voice — halving the size again with no real cost. Below that you start hearing it.

Will compressing damage the audio?

You're stacking a second lossy generation. At a generous bitrate that's inaudible, but if you still have a lossless original, encode from that instead: one generation always beats two.

Should I compress a master or an archive copy?

Never the master. Compress a copy for sharing and listening, and keep the original — you can always re-encode from it, but you can never re-create what a lossy encoder discarded.

Is this compressor free?

Yes. Free users get 5 conversions per month. The output is limited to the first 10 seconds as a preview, with a 20MB input file size limit. Upgrade to Pro for unlimited, full-length conversions.
