What is AIFF?

Apple's uncompressed format. Similar to WAV but with better metadata support. Used in professional Mac audio workflows.

What is WAV?

Uncompressed audio format. Perfect quality with no data loss. Standard for music production and professional audio work.

Why Convert AIFF to WAV?

AIFF to WAV is the rare conversion with zero quality trade-off to weigh: both formats store exactly the same thing — uncompressed PCM samples — differing only in packaging (AIFF is Apple's container storing samples big-endian, WAV is the Microsoft/IBM one storing them little-endian). Converting rewrites the wrapper and byte order; the audio that comes out is sample-for-sample identical to what went in. Nothing is lost, nothing could be. So the only question is compatibility, and that is exactly why people convert: WAV is the default uncompressed format everywhere outside the Mac. Windows audio editors, samplers and hardware units, older DAWs, video tools, CD-burning software, game engines, and countless upload forms accept WAV without a second thought, while some of them refuse .aiff or import it clumsily. If you work on a Mac and hand files to Windows collaborators, feed hardware samplers, or submit audio to systems that list WAV among their accepted formats, converting your AIFFs removes the friction with literally no downside. File size stays essentially the same (both are uncompressed, about 10 MB per stereo minute). The conversion runs locally in your browser, instantly for typical files.

Who Uses This Converter

Mac-to-Windows handoffs

Send WAV and your collaborator's software opens it instantly — no AIFF surprises.

Hardware samplers & decks

Most hardware expects WAV. Convert AIFF one-shots and loops so they load first try.

Video & CD workflows

NLEs and CD-burning tools take WAV universally; AIFF support varies.

Upload requirements

Forms that list WAV among accepted formats get exactly what they ask for — same audio, zero loss.

Frequently Asked Questions

Is AIFF to WAV lossless?

Yes, 100%. Both formats store uncompressed audio. Converting between them changes only the container, not the audio data.

Why not just use AIFF everywhere?

WAV has broader support, especially on Windows and in cross-platform tools. AIFF is primarily a Mac format.

Are the file sizes the same?

Nearly identical. Both store uncompressed audio. You might see a tiny difference due to header/metadata formatting, but audio data size is the same.

Which format supports better metadata?

AIFF has better built-in metadata support. WAV traditionally has limited metadata, though modern tools handle this well with ID3 tags in WAV.

Is AIFF to WAV really lossless?

Completely. Both formats hold the same uncompressed PCM samples — the conversion changes the container and byte order, and the audio is bit-identical in content. There is no quality decision to make.

Will the file size change?

No meaningful change — both formats are uncompressed, about 10 MB per stereo minute at CD quality. You are swapping packaging, not compression.

Why do some programs reject AIFF but accept WAV?

WAV became the universal default for uncompressed audio on Windows and cross-platform software, so many tools only implement WAV. AIFF support outside Apple software is inconsistent — converting sidesteps the issue entirely.

Is this AIFF to WAV converter 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.
