WAV to AIFF
Convert WAV audio to AIFF right in your browser, with nothing uploaded.
Drag & drop your WAV files here, or click to choose. Everything runs in your browser — nothing is uploaded.
WAV is uncompressed PCM audio: flawless quality, but very large files at roughly 10 MB per minute of CD-quality stereo. AIFF is essentially WAV's Apple counterpart, also uncompressed PCM, just with the samples stored big-endian. That is why people convert WAV to AIFF: not to save space or improve the sound, but because a Mac-based workflow such as Logic Pro, an older Apple audio application or a hardware sampler expects AIFF specifically. Both formats are lossless, so the audio is identical and there is no bitrate to choose. This converter runs entirely inside your browser on a WebAssembly build of FFmpeg, so nothing is ever uploaded. Drop in several WAV files at once, preview each result, and download. Free, no signup, no watermark.
Frequently Asked Questions
How do I convert WAV to AIFF?
Drag and drop your WAV files onto the drop area, or click it to choose them from your device. Conversion starts automatically as soon as the files are added, and each file is processed one after another. When a file finishes, it appears as a row showing its new AIFF filename, its size, an inline preview player, and a Download button. Everything runs in your browser through a WebAssembly build of FFmpeg, so your audio is never uploaded anywhere. You can add several WAV files at once and download each AIFF as it completes.
Does converting WAV to AIFF lose any quality?
No. WAV and AIFF are both uncompressed PCM formats, so converting between them is completely lossless: the samples that come out are identical to the ones that went in, and nothing is re-encoded, discarded or degraded. The two formats differ mainly in byte order, WAV being little-endian and AIFF big-endian. Because no compression is involved, there is no bitrate setting for either format, since neither one throws audio data away.
Is this WAV to AIFF converter free and private?
Yes, it is completely free with no signup, no account and no watermark, and it is private because the conversion happens entirely inside your own browser using WebAssembly. Your WAV files are never uploaded to any server, which makes it safe for unreleased music, client sessions and confidential recordings. There is no software to install either. The FFmpeg engine downloads once, about 32 MB, the first time you convert, then your browser caches it so later conversions start instantly.
Is there a file size limit for WAV files?
There is no size limit imposed by the site, because your files never leave your device: the only real limit is how much memory your browser and computer have available. Long WAV recordings are large by nature, around 10 MB per minute of CD-quality stereo, so a full session can run to hundreds of megabytes. Files over roughly a few hundred MB can be slow or exhaust memory on a phone, so for long recordings a desktop browser is the better choice.
Why does my studio software or sampler want AIFF instead of WAV?
AIFF is Apple's uncompressed PCM format, so it is the native expectation in Logic Pro, in older Mac audio applications and in some hardware samplers built around Apple workflows, even though it holds exactly the same audio a WAV does. Converting is a container and byte-order change, not a quality change. If your software happily accepts either format, there is no sonic reason to prefer one, so convert only when a tool, template or delivery spec specifically asks for AIFF.
Will the AIFF file be bigger than my WAV file?
No, an AIFF converted from WAV comes out roughly the same size, because both formats store the same uncompressed PCM samples and differ only in a small header and byte order. Neither format compresses the audio, so a minute of CD-quality stereo takes about 10 MB in either one. If you want the same lossless audio in a much smaller file, convert to FLAC instead, which is also lossless but sits at roughly 50 to 60 percent of WAV's size.
Does this work on a Mac, iPhone or Android phone?
Yes. The converter works in any modern browser on Windows, Mac, Linux, iPhone and Android, because all the work is done by WebAssembly on your own device rather than by a server, so there is nothing to install and no app to download on any platform. Phones have far less memory than desktops, so very large or very long WAV files can be slow or fail on mobile. For big session files, a Mac or PC browser is the safer option.
