HOW TO CONVERT AIFF → WAV
Upload the AIFF
Drop or select your AIFF file. The upload is encrypted and the file is queued for conversion.
Transcode via FFmpeg
FFmpeg decodes the AIFF stream to PCM internally, then re-encodes as WAV at the bitrate you select.
Download the WAV
The WAV is delivered as a direct download; metadata and cover art transfer automatically where possible.
AIFF is Apple's uncompressed Audio Interchange File Format, the macOS equivalent of WAV. That is why users land on this page looking for a WAV copy. Converting AIFF to WAV changes the audio container without re-recording anything. Whether you are moving from a studio master to a distribution format or just making a file playable on an old car stereo, KaijuConverter re-encodes the audio with FFmpeg at your chosen bitrate and preserves sample rate, channels and ID3 tags. The source AIFF file stays untouched. A quick refresher — AIFF is Apple's uncompressed Audio Interchange File Format, the macOS equivalent of WAV. By contrast, WAV is Microsoft's uncompressed PCM container — the studio master format on Windows.
Why convert AIFF to WAV
AIFF Audio is great in its own niche, but WAV Audio is either more universally playable or better suited to the device you are targeting. Converting lets you ship the audio without asking listeners to install a codec. The loss in quality between the two is negligible at sensible bitrates.

AIFF vs WAV — Strengths and limitations
What each format does best, and where it falls short.
AIFF Strengths
- Lossless and uncompressed — bit-exact audio reproduction.
- Native to macOS and all Apple Pro Audio apps.
- Simple structure — trivially parsed by audio libraries.
- Supports up to 32-bit float, 192 kHz, and multi-channel audio.
- Rich metadata via named chunks (annotations, markers, MIDI).
Limitations
- Enormous file sizes — 10 MB per minute at CD quality.
- No built-in compression — use FLAC for lossless with smaller files.
- Big-endian byte order confuses tools written on little-endian hardware.
WAV Strengths
- Bit-perfect, uncompressed audio — the professional studio standard.
- Universally supported for playback, editing, and analysis.
- No re-encoding penalty — edit and save repeatedly with zero quality loss.
- Simple internal structure — easy to parse programmatically.
- Supports up to 32-bit float and 384 kHz sample rates.
Limitations
- Enormous file sizes — 10 MB per minute for CD-quality stereo.
- 4 GB size limit for standard WAV (RF64/W64 variants extend it but break compatibility).
- No native support for cover art or rich metadata.
Quality & Compatibility
Lossy-to-lossy transcoding (most cross-format audio jobs) loses a tiny amount of quality on each pass — usually inaudible at our default VBR ~190 kbps for music or 96 kbps for speech. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy is only as good as the target bitrate you choose.
Tips for Best Results
- Pick 128 kbps for podcasts and voice, 192–256 kbps for music, 320 kbps only if the audio will be edited further downstream.
- Keep the AIFF master alongside the WAV — re-encoding a lossy format twice accumulates audible artefacts.
- For mono voice content, convert to mono WAV explicitly to halve file size without any quality loss.
Frequently Asked Questions
Lossy-to-lossy conversions (most combinations) re-compress the audio, which technically introduces some loss. At a 192 kbps or higher target it is inaudible on normal equipment. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy transcodes are only as good as the target bitrate you choose.
For voice content (podcasts, audiobooks, lectures) 128 kbps is indistinguishable from higher bitrates. For music, 192-256 kbps covers most listening; 320 kbps is the ceiling for WAV and the right choice for audio you plan to edit further. Above that, prefer a lossless target instead.
Yes. Title, artist, album, year and cover art travel from the AIFF container to the WAV container automatically where both formats support them. If a tag field has no WAV equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
AIFF Audio
Source formatAIFF is Apple's uncompressed audio format, equivalent to WAV in the macOS ecosystem. It stores CD-quality PCM audio and is widely used in professional audio production on Apple hardware.
WAV Audio
Target formatWAV is an uncompressed audio format that preserves full audio fidelity. Files are large but provide lossless, CD-quality sound. It is the standard working format in audio production and editing.
Going the other way? Convert WAV back to AIFF with the same engine.
Common Use Cases
Share across platforms
Send WAV files to anyone without worrying about whether they have the right software for AIFF.
Embed in documents
Drop WAV output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
WAV often produces smaller files than AIFF for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
