WAV to AIFF Conversion FAQ
What bitrate does the AIFF file end up at?
+
A lossy AIFF is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless AIFF (WAV, FLAC) ignores the bitrate and keeps every sample.
Is WAV to AIFF genuinely lossless?
+
Yes. Both formats keep every sample, so decoding the AIFF returns a bit-identical copy of the audio inside the WAV. Nothing is quantised, nothing is discarded, and the conversion can be repeated indefinitely without accumulating artefacts. What changes is the file size and which software will open it. WAV normally stores raw uncompressed PCM — every sample kept exactly, at whatever bit depth and sample rate was captured. AIFF stores uncompressed big-endian PCM — the Apple-side equivalent of WAV, with the same bit-for-bit fidelity.
Can I tag the AIFF with artist and album information?
+
Yes, and it is a genuine gain over WAV, which has nowhere dependable to store any of it. AIFF carries title, artist, album, year, track number and embedded cover art in the container itself, so a music library files it correctly without a manual pass. AIFF is the studio interchange format on macOS, handles metadata better than plain WAV, and imports into Logic and Pro Tools instantly.
Will the AIFF play in my car or on older hardware?
+
Often not. WAV is decoded by essentially everything, including car head units and elderly players; AIFF needs software that knows the codec, which standalone hardware frequently does not have. If the destination is a car stereo or a portable player, that is a strong argument for staying on WAV. AIFF is as large as WAV with worse support outside the Apple world, so it is a poor choice for distribution.
Will going from WAV to AIFF actually reduce my audio quality?
+
If WAV is lossy (MP3, AAC) and AIFF is lossless (WAV, FLAC), the AIFF is no better than the WAV — you cannot recover information already discarded by the lossy WAV codec. If WAV is lossless and AIFF is lossy, expect the AIFF encoder to recompress; at 192 kbps the loss is imperceptible to most ears.
Can I batch-convert hundreds of WAV files into AIFF?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Can I normalize loudness in the WAV to AIFF step?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished AIFF through a Normalize tool on this site.
Will the AIFF play on my car stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports.
Is my WAV file private during conversion?
+
Yes. Uploaded WAV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AIFF are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
