Convert AIFF to MP3
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 MP3 conversion
- Sample rate and bit depth preserved or downsampled for MP3 compatibility
What is MP3?
MP3
MP3 uses lossy psychoacoustic compression based on Modified Discrete Cosine Transform (MDCT), reducing audio file size approximately 10:1 by removing frequencies outside human hearing range or masked by louder sounds. Supports constant bitrate (CBR) and variable bitrate (VBR) encoding from 32kbps to 320kbps. Standard CD-quality approximation achieved at 320kbps. Universally compatible across all playback devices and software.
- MP3 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
- Perceptual coding removes frequencies inaudible to human hearing
- Universal browser and device support—no compatibility concerns
Why Convert AIFF to MP3?
✓ Cross-Platform Playback
MP3 plays everywhere AIFF might struggle—old MP3 players, car audio systems, budget smartphones, and legacy software all handle MP3 without requiring modern codec support.

Frequently Asked Questions
What's the batch limit for .aiff to .mp3 conversion?
Our free tier allows 3 .aiff files per batch conversion. Premium tier supports up to 20 .aiff files with automatic .mp3 packaging. Perfect for bulk processing.
Is AIFF to MP3 conversion truly private?
Yes—truly private. AIFF to MP3 conversion executes entirely client-side. No uploads, no servers, no logging. We physically cannot access your files.
Is there a file size cap for AIFF to MP3 conversion?
Free accounts: 100MB cap. Premium accounts: 500MB cap. Standard AIFF files convert easily. Larger audio files require Premium subscription.
What's the average AIFF to MP3 conversion speed?
Nearly instant for typical AIFF files. Browser-based MP3 conversion processes files locally: 1-3 seconds for small files, 5-15 seconds for larger audio content. No server upload—conversion starts immediately.
