WAV to AIFF Converter
Processing entirely on your device — large files may take a moment.
WAV Audio and Audio Interchange File Format exist for different jobs: WAV is uncompressed PCM audio — the raw format of CDs and studio work, with perfect quality and correspondingly large files. AIFF imports cleanly into Logic Pro and older Mac audio tooling.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the WAV format
WAV is the simplest possible audio file: PCM samples — the raw digits of the waveform — inside a RIFF container. CD-quality stereo (44.1 kHz, 16-bit) runs about 10 MB per minute, and studio work uses 24-bit/48–96 kHz without blinking. Every DAW, every interface and every phone records to it; nothing about it can be misinterpreted.
That perfection is why WAV remains the format of recording and editing: every sample is bit-exact, so processing, slicing and mixing never fight artifacts. And it is why nobody streams it — ten megabytes a minute is storage money, not delivery.
+ Strengths
- ✓Bit-perfect, zero-loss audio
- ✓The editing and recording standard
- ✓Supports hi-res depths and sample rates
! Limitations
- −Enormous files (~10 MB/minute at CD quality)
- −Tagging is an afterthought (BWF fills the gap)
- −Impractical for streaming or phones-on-the-go libraries
About the AIFF format
AIFF is Apple's counterpart to WAV: uncompressed PCM in an IFF container, born with the classic Mac in 1988. It stores the same bit-perfect audio as WAV but carries metadata far better — iTunes-era tags, cover art and loop points all fit natively, which made it the default of Logic Pro and Mac-based audio production.
Functionally the WAV-versus-AIFF choice is platform history: same quality, same sizes, AIFF friendlier on Mac, WAV friendlier everywhere else. Converting between them is a lossless retagging exercise, nothing more.
+ Strengths
- ✓Bit-perfect uncompressed audio
- ✓Better metadata support than WAV
- ✓Native to macOS and Logic Pro
! Limitations
- −Same bulk as WAV (~10 MB/minute)
- −Windows tooling historically prefers WAV
Why convert WAV to AIFF?
Converting makes sense where the strengths of AIFF meet what WAV cannot give you. Bit-perfect uncompressed audio Meanwhile Enormous files (~10 MB/minute at CD quality) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this WAV to AIFF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WAV to AIFF?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will converting WAV to AIFF reduce audio quality?
If AIFF is lossless, the output contains everything the WAV file contains — no further loss is added. If AIFF is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Can I convert a whole folder of WAV files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
