WAV to AIFF Conversion FAQ
What bitrate does the AIFF file use?
+
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 reduce my audio quality?
+
If WAV is lossy and AIFF is lossless (e.g. MP3 → WAV), the AIFF file is no better than the WAV — you can't recover information that's already been thrown away. If WAV is lossless and AIFF is lossy, expect the AIFF codec to recompress; at 192 kbps this is transparent for most content.
Can I batch convert hundreds of WAV files to 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.
Will the AIFF keep the same sample rate as WAV?
+
By default yes (48 kHz WAV → 48 kHz AIFF). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.
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 / audiobook app?
+
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. Nobody listens to or shares the audio, which matters for personal audiobook libraries, and uploaded WAV files and their converted copies are deleted automatically about 24 hours after conversion.
