Convert AAC to AIFF
What is AAC?
AAC
AAC (Advanced Audio Coding) uses lossy psychoacoustic compression with better efficiency than MP3 at equivalent bitrates. Supports 8-96 channels, sampling rates up to 96kHz, and bitrates from 8kbps to 320kbps. Part of MPEG-4 standard. Achieves transparent quality at lower bitrates than MP3. Default codec for iTunes, YouTube, and streaming services. Universally compatible across modern devices.
- AAC encodes audio using lossy compression at various bitrates
- Lossy source limits AIFF quality ceiling—cannot restore removed frequencies
- Sample rate and bit depth preserved or downsampled for AIFF compatibility
What is AIFF?
AIFF
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format storing PCM waveform data at CD quality (44.1kHz, 16-bit) or higher. Similar to WAV but Mac-native. Large file sizes (10MB per minute at CD quality) but perfect audio fidelity. Converting to other audio formats involves compression decisions.
- AIFF encodes audio using lossless compression at various bitrates
- Lossless audio data provides full fidelity for AAC conversion
- Sample rate and bit depth preserved or downsampled for AAC compatibility

Frequently Asked Questions
How many .aac files can I convert at once?
Free users: 3 .aac files per batch. Premium users: 20 .aac files per batch with ZIP download. Each .aac file converts independently to .aiff, maintaining original quality and filenames.
Do AAC files leave my device during AIFF conversion?
Never. AAC to AIFF conversion uses WebAssembly technology running in your browser. Files process on your device only. We have zero access to your AAC data.
Can I convert large AAC files to AIFF?
Free users: AAC files up to 100MB. Premium users: AAC files up to 500MB. Both tiers handle typical audio files easily. Upgrade for professional AIFF conversion of larger AAC assets.
What's the processing time for converting AAC to AIFF?
AAC to AIFF conversion runs in your browser, making it extremely fast. Files under 10MB convert in 1-5 seconds. Larger AAC files may take 10-20 seconds depending on file complexity and your device's processing power.
