Convert AIFF to OGG Online

"Online converter" normally means uploading your file to someone's server, waiting in a queue, and downloading the result. This page inverts that: it loads FFmpeg compiled to WebAssembly into your browser and does the work on your own machine. You keep the convenience of online — nothing to install, works on any OS — without the upload.

A minute of AIFF is about 10 MB; the same minute as OGG is roughly 1.2. Across an album or a long recording that difference decides whether it fits on a phone. That matters here, because transfer is where server-based converters spend most of their time. With no upload and no download of the result, what's left is just the conversion itself: usually a second or two.

AIFF files typically come from Logic Pro and GarageBand bounces, old iTunes rips, and Mac sample libraries — and AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. Keep the AIFF. It's the archival master; the OGG is the copy that travels. Re-encode from the master whenever you need another format or bitrate.

Because it's a web page rather than software, the same converter runs on Windows, macOS, Linux, ChromeOS, iPhone, and Android — with nothing to keep updated and none of the bundled adware that comes with downloadable free converters.

The AIFF on your drive almost certainly started life in Logic Pro and GarageBand bounces, and 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. A minute of AIFF is about 10 MB; the same minute as OGG is roughly 1.2. Across an album or a long recording that difference decides whether it fits on a phone. 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.
