What is AIFF?

AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, equivalent to WAV on Windows. Developed by Apple in 1988 based on Electronic Arts' IFF format, AIFF stores CD-quality audio without any compression.

AIFF is the standard format for professional audio on Mac, used in GarageBand, Logic Pro, and Final Cut Pro. The format preserves complete audio fidelity, making it ideal for editing and mastering.

Why Convert AIFF Files?

AIFF files are large—about 10MB per minute of stereo audio. Convert when you need:

  • Smaller file sizes – AIFF is impractical for portable devices
  • Cross-platform sharing – Windows users may prefer WAV or MP3
  • Streaming upload – Platforms typically require compressed formats
  • Archival compression – FLAC provides lossless compression

Convert AIFF to Other Formats

AIFF to MP3

Compress for portable devices and sharing. MP3 at 320kbps delivers quality acceptable for most listening while reducing file size by 90%.

AIFF to WAV

Convert for Windows compatibility. WAV and AIFF are both uncompressed and equivalent in quality—this is a container change, not a quality change.

AIFF to FLAC

Lossless compression reducing file size by 50-60% while preserving every bit of audio data. Perfect for archiving your AIFF collection.

AIFF to M4A

Create AAC files for iTunes and Apple devices. M4A provides excellent quality at much smaller file sizes.

Convert Other Formats to AIFF

Create AIFF files for Mac audio production:

WAV to AIFF

Convert Windows audio for Mac workflows. No quality change—both are uncompressed formats.

MP3 to AIFF

Prepare compressed audio for editing. Note: Converting MP3 to AIFF creates an uncompressed file but cannot restore quality lost in MP3 compression.

FLAC to AIFF

Decompress lossless files for Mac editing software that may not support FLAC natively.

AIFF Technical Specifications

  • Full name: Audio Interchange File Format
  • Developer: Apple Computer
  • File extension: .aiff, .aif
  • Compression: Uncompressed (lossless)
  • Bit depth: 8, 16, 24, 32-bit
  • Sample rates: 22.05 kHz to 192 kHz
  • Typical bitrate: 1411 kbps (CD quality 16-bit/44.1kHz)

AIFF vs WAV

Both AIFF and WAV store uncompressed audio at identical quality. The differences are:

  • Platform origin: AIFF is Mac, WAV is Windows
  • Metadata: AIFF handles metadata slightly differently
  • Software support: Mac software may prefer AIFF, Windows software WAV
  • Quality: Identical when using same bit depth and sample rate

How to Convert AIFF Files

  1. Upload your AIFF file – Select your audio file
  2. Choose your output format – MP3, WAV, FLAC, M4A, and more
  3. Download converted file – Get your audio in the new format

Works on Any Device

Convert AIFF files in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android

Pro Tip

For music production, record and edit in AIFF at 24-bit/48kHz or higher. Export to compressed formats only as the final delivery step to preserve maximum quality during the creative process.

Common Mistake

Converting MP3 to AIFF expecting quality improvement. The AIFF file will be larger but contains only the quality present in the MP3. Always work from original sources when possible.

Best For

Mac-based audio production, editing, mastering, and archiving. AIFF is the professional standard for uncompressed audio on Apple platforms.

Not Recommended

Avoid AIFF for portable music libraries or sharing online. File sizes are impractical—convert to FLAC for lossless archiving or MP3/AAC for portable use.

Frequently Asked Questions

AIFF (Audio Interchange File Format) is Apple's uncompressed audio format, equivalent to WAV. It stores CD-quality audio without compression, commonly used in professional Mac audio production.

Quality is identical—both are uncompressed. AIFF is preferred on Mac, WAV on Windows. Choose based on your platform and software preferences.

AIFF is uncompressed, storing every audio sample. CD-quality AIFF uses about 10MB per minute. This preserves quality but requires significant storage.

Use AIFF for editing, mastering, and archiving where quality matters. Use MP3 for sharing, portable devices, and when file size is a concern.

Yes, most Windows media players support AIFF, though WAV is more common. Converting AIFF to WAV ensures maximum Windows compatibility.

Yes. MP3 is lossy compression that discards some audio data. Use high bitrates (256-320kbps) to minimize audible quality loss.

AIFF-C (AIFF Compressed) is a variant that supports compression. However, it is rarely used—most AIFF files are uncompressed.

Excellent. AIFF is standard in Mac-based music production with Logic Pro, GarageBand, and other DAWs. Its uncompressed nature preserves quality through editing.
