Frequently Asked Questions
Why convert AIFF to M4A?
AIFF (Audio Interchange File Format) uses uncompressed lossless encoding and is best for Apple professional audio — Logic Pro, GarageBand, and macOS music production workflows. M4A (MPEG-4 Audio) uses lossy or lossless (AAC/ALAC) encoding and excels at Apple ecosystem — iTunes, iPhones, iPads, and macOS music libraries. 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.
