AIFF to WAV: the same samples, byte-swapped

Both formats hold uncompressed PCM. The difference is byte order and chunk layout: AIFF came from Apple and stores samples big-endian in IFF chunks, WAV came from Microsoft and stores them little-endian in RIFF chunks. The conversion reverses the byte order and rewrites the header. The audio itself is bit-for-bit identical, so this is genuinely lossless.

Convert when a Windows application or an older DAW refuses AIFF. Because nothing is re-encoded you can convert back and forth indefinitely without any generational loss.

AIFF to WAV FAQ

Quick answers about compatibility, quality, metadata handling, and the most common reasons to convert AIFF files to WAV.

How do I convert AIFF to WAV?

Upload your AIFF audio to iFormat and click Convert. The track is decoded and re-encoded to WAV with metadata preserved. It's free, needs no account, and supports batch conversion of albums or playlists.

How to convert AIFF to WAV without losing sound quality

WAV is an uncompressed lossless audio format. Converting to a lossless target (WAV, FLAC, AIFF) preserves every detail of the original. Converting between lossy formats involves a small, usually inaudible re-encoding step. For the best result, always start from the highest-quality source file you have.

Can I convert multiple AIFF files to WAV at once?

Yes — upload an entire album or playlist of AIFF files and iFormat batch-converts them all to WAV. Metadata (title, artist, album, cover art) carries over for each track, so your library stays organised after conversion.

Why convert AIFF to WAV instead of keeping AIFF?

AIFF is Apple's uncompressed audio format used for professional audio on Mac. WAV is better for editing and mastering at full quality. Convert when the destination device, app, or platform handles WAV more reliably than AIFF.

Does AIFF to WAV conversion keep track info like artist and album?

Yes — ID3 metadata such as title, artist, album, and cover art carries over automatically wherever the WAV format supports it, so your library stays organised after conversion.

What is AIFF?

AIFF is Apple's uncompressed audio format, typically used for professional audio on Mac. Converting it to WAV makes the file easier to open, share, or upload where AIFF is not supported.
