Convert AIFF to OGG

About AIFF and OGG

AIFF is Apple's uncompressed audio format — the same raw PCM as WAV in a different wrapper, dating back to 1988. It is still the native interchange format for Logic Pro and much of the Mac production world, and converts to WAV with zero quality change.

OGG Vorbis is a free, open lossy codec that beats MP3 at equivalent bitrates. It is common in game audio and open-source software, and every modern browser plays it.

Converting AIFF to OGG is lossy. 192 kbps is transparent for most listeners on most material; pick 320 kbps for the ceiling, or drop lower when small files matter more than fidelity.

How the conversion works

This tool runs FFmpeg — the same engine behind most media software — compiled to WebAssembly, entirely in the browser. The file is read locally, converted locally and saved straight from memory; nothing is ever uploaded, which also means no queues and no server-side file size limits.

The converter itself is a one-time ~31 MB download on the first conversion, cached by the browser afterwards. Once it is loaded, everything works offline.
