Quality rule

Conversion changes format and compatibility. It does not restore quality, resolution, or audio detail that was missing from the original file.

Understanding AAC and AIFF formats

What is AAC?

AAC is a lossy audio format used by many phones, browsers, and streaming workflows. It is designed to keep speech and music clear at smaller file sizes.

Best for: Apple devices, mobile playback, online audio, and efficient music or voice files.

What is AIFF?

AIFF is an uncompressed audio format commonly associated with Apple and professional audio workflows. It keeps audio easy to edit but creates large files.

Best for: Mac-based editing, audio production, archival copies, and handoff to creative tools.

Why convert AAC to AIFF?

Use AIFF when you need an editing-friendly or archive-friendly audio file.
AIFF can make the file easier to process in audio tools, but it cannot restore detail removed by earlier lossy compression.
Keep the original source file so you can make future conversions without adding another generation of loss.
