Convert WAV to AIFF Online Free
Convert WAV audio to AIFF format for use in Apple DAWs and macOS workflows. Both formats are uncompressed PCM audio — this conversion simply rewraps the audio in the AIFF container.
ChangeThisFile converts your WAV to AIFF using FFmpeg on secure servers. Both WAV and AIFF contain uncompressed PCM audio, so this is a lossless container conversion with no quality loss. AIFF is the native format for Logic Pro and macOS audio workflows. Files are auto-deleted after conversion, free with no signup.

WAV vs AIFF: Format Comparison
Key differences between the two formats
| Feature | WAV | AIFF |
|---|---|---|
| Developer | Microsoft / IBM | Apple Inc. |
| Container Format | RIFF | IFF (Interchange File Format) |
| Audio Encoding | Uncompressed PCM | Uncompressed PCM |
| Quality Loss on Conversion | None (lossless rewrap) | None (lossless rewrap) |
| Platform Strength | Windows / Cross-platform | macOS / Apple |
| Metadata Format | RIFF INFO chunks / ID3 | AIFF chunk metadata + markers |
| Loop Point Support | Limited (RIFF smpl chunk) | Yes (MARK and INST chunks) |
| Max Bit Depth | 32-bit float | 32-bit integer |
When to Convert
Common scenarios where this conversion is useful
Logic Pro and GarageBand project import
Logic Pro works natively with AIFF. Convert WAV files recorded on Windows or Linux into AIFF for seamless import into Logic Pro projects without format warnings.
macOS audio workflow compatibility
Many macOS audio tools and AppleScript-based workflows prefer AIFF. Convert WAV recordings to AIFF to fit into macOS-centric production environments.
Adding loop points for samplers
AIFF supports MARK and INST metadata chunks for defining loop points. Convert WAV samples to AIFF before adding loop metadata for use in samplers like EXS24.
Broadcast delivery on macOS systems
Some macOS broadcast systems and playout software require AIFF deliverables. Convert WAV masters to AIFF to meet broadcast delivery specifications.
CD track preparation with iTunes
iTunes on macOS natively handles AIFF for CD burning. Convert WAV tracks to AIFF to import them directly into iTunes for CD authoring without format conversion steps.
How to Convert WAV to AIFF

2
Convert to AIFF
Click Convert. FFmpeg remuxes the PCM audio from the WAV RIFF container into an AIFF IFF container. Since both formats use uncompressed PCM, there is no audio re-encoding.

3
Download your AIFF file
Download the resulting AIFF file. It is automatically deleted from our servers after you complete the download.
Frequently Asked Questions
Yes. Both WAV and AIFF store uncompressed PCM audio data. Converting between them is a lossless container rewrap — the audio samples are identical and no quality is lost in the process.
Yes. FFmpeg preserves the original bit depth (e.g., 16-bit or 24-bit) and sample rate (e.g., 44100 Hz or 48000 Hz) from the WAV file when creating the AIFF output.
Yes. Logic Pro natively supports AIFF files. You can drag the converted AIFF directly into a Logic Pro project or Audio Files browser without any additional conversion.
Basic metadata like sample rate and bit depth is preserved. However, WAV-specific RIFF metadata chunks (like RIFF INFO tags) may not fully transfer to AIFF format. For detailed metadata, you may need to re-tag the AIFF after conversion.
WAV is better for Windows. Windows natively supports WAV in all versions. AIFF lacks native Windows support and requires third-party software like iTunes, VLC, or a DAW to play on Windows.
Yes. FFmpeg handles 16-bit, 24-bit, and 32-bit WAV files and correctly writes the corresponding AIFF output with the same bit depth.
Because both formats store the same uncompressed PCM audio data. The file sizes will be nearly identical — the small difference is due to different header and metadata structures in the RIFF vs IFF containers.
Yes. Your WAV file is uploaded over HTTPS, processed by FFmpeg on our server, and automatically deleted after download. We do not retain or review your audio files.
AIFF uses uncompressed PCM audio. AIFC (AIFF-Compressed) is a variant that can store compressed audio. This converter always outputs standard uncompressed AIFF, not AIFC.
