Compress AIFF to OGG

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

AIFF (.aiff) · Max 20 MB

AIFF files are uncompressed and huge. OGG uses lossy compression to shrink them by 90% or more. 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.

Expect roughly 8× smaller: AIFF runs about 10 MB per minute, OGG about 1.2. Because AIFF is uncompressed, this is the ideal encode: the encoder sees the complete original signal, so the OGG is the cleanest that audio can produce.

AIFF is the format of Logic Pro and GarageBand bounces. It plays where it was made, but AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. Storage-wise you're looking at about 8× less: 10 MB per minute becomes roughly 1.2. Because AIFF is uncompressed, encoding to OGG here is the clean, single-generation case — the encoder sees the whole original signal, so this OGG is as good as the format gets.

Frequently Asked Questions

How much smaller will the file get?

Expect roughly 8× smaller: AIFF runs about 10 MB per minute, OGG about 1.2.

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?

Because AIFF is uncompressed, this is the ideal encode: the encoder sees the complete original signal, so the OGG is the cleanest that audio can produce.

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.
