Frequently Asked Questions
Why convert AIFF to AAC?
AIFF (Audio Interchange File Format) uses uncompressed lossless encoding and is best for Apple professional audio — Logic Pro, GarageBand, and macOS music production workflows. AAC (Advanced Audio Coding) uses lossy compressed encoding and excels at modern streaming services, YouTube, and devices where AAC is the native codec. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
What bitrate for previews?
128 kbps AAC — full-bandwidth enough for approvals on any device. Masters stay AIFF/FLAC; previews travel light.
Why not MP3?
AAC sounds better per bit and Apple prefers it; MP3 only where legacy demands. Default AAC for 2026 sharing.
Loudness for sharing?
Normalize previews to −14 LUFS so clients hear intended balance on phones. Masters keep headroom separately.
Do bounce files upload?
No — conversion runs locally in your browser with FFmpeg. Saves never touch a meter — downloads on local tools are unlimited.
