Convert AIFF to AAC
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
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

Frequently Asked Questions
Can I drag several .aiff files for batch .aac conversion?
Multi-file support included. Drag up to 3 .aiff files (free) or 20 files (Premium) for instant batch .aac conversion with preserved quality.
Do AIFF files leave my device during AAC conversion?
Never. AIFF to AAC conversion uses WebAssembly technology running in your browser. Files process on your device only. We have zero access to your AIFF data.
Can I convert large AIFF files to AAC?
Free users: AIFF files up to 100MB. Premium users: AIFF files up to 500MB. Both tiers handle typical audio files easily. Upgrade for professional AAC conversion of larger AIFF assets.
What's the processing time for converting AIFF to AAC?
AIFF to AAC conversion runs in your browser, making it extremely fast. Files under 10MB convert in 1-5 seconds. Larger AIFF files may take 10-20 seconds depending on file complexity and your device's processing power.
Do I need to install any software?
No! Everything works directly in your web browser. No downloads, no installations, no plugins required. Just upload your file and convert. Works on Windows, Mac, Linux, and mobile devices.
