AIFF is Apple's classic uncompressed audio container — the Mac counterpart to WAV. Same raw PCM audio, same huge files, mostly seen in pro-audio sessions and older Mac workflows.
WAV stores raw, uncompressed PCM samples — the audio equivalent of a bitmap. Files are huge, but every editor, DAW and operating system opens them without a second thought.
Converting AIFF to WAV is essentially a container swap: the raw PCM samples are identical and the file size barely changes — you do it when a tool or plugin only accepts WAV.
AIFF vs WAV
| AIFF | WAV | |
|---|---|---|
| Compression | lossless — nothing discarded | lossless — nothing discarded |
| Codec / container | uncompressed PCM in Apple's AIFF container | uncompressed 16-bit PCM in a RIFF container |
| Typical file size | very large — roughly 10 MB per minute, like WAV | very large — roughly 10 MB per minute of 16-bit stereo |
| Best for | Mac pro-audio sessions and sample libraries | editing, DAWs and audio production |
| Strength | uncompressed PCM, like WAV; native on macOS | universal uncompressed PCM — ideal for editing |
| Watch out for | huge files; rarer than WAV outside Apple software | huge files for what they hold |
| Compatibility | native on macOS; most editors elsewhere open it too | universal — opens in every editor and OS |
How the conversion works
- Choose your AIFF file (up to 10 MiB). The button above opens the converter with WAV already selected as the target format.
- There is no bitrate to choose: WAV is lossless, so the bitrate field is simply ignored.
- Run the conversion and download the result — the output keeps your filename with a .wav extension. Everything happens locally: the page runs ffmpeg compiled to WebAssembly, so your audio is never uploaded to a server.
What to expect
Nothing is lost either way. AIFF and WAV both store audio losslessly, so the samples come through bit for bit — only packaging and file size change. The bitrate setting doesn't apply to a lossless target.
Embedded album art is dropped along the way: cover images ride along as a video stream, which audio-only outputs like WAV can't carry.
FAQ
Is converting AIFF to WAV really lossless?
Yes — both formats store the audio losslessly, so the conversion is bit-transparent. What changes is packaging and file size, not sound.
What actually changes between AIFF and WAV?
Only the container. Both hold raw PCM samples, so the audio bytes and the file size stay essentially the same — the point is compatibility with tools that only read WAV.
Is my AIFF file uploaded when converting to WAV?
No. The page downloads an ffmpeg WebAssembly build once, then converts your file locally in the browser tab — the audio never leaves your device. Input files up to 10 MiB are supported.
