Convert AIFF to WAV 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.

Disk usage barely moves — this conversion buys compatibility rather than space. 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. Every sample makes it across intact. The only thing that changes is the container.

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.

Most people meet AIFF through Logic Pro and GarageBand bounces. It is a fine format there; the trouble is that AIFF is uncompressed like WAV, so a four-minute song is 40 MB+ and won't attach to an email. WAV is the destination when you need uncompressed, edit-ready audio that every DAW and editor accepts. Disk usage barely moves — this conversion buys compatibility rather than space. Both AIFF and WAV are lossless, so this specific conversion is bit-perfect: every sample survives and you can go back to AIFF later without any loss.
