Why AIFF files are used
Audio Interchange File Format files store digital audio using the .aiff extension.
Audio formats differ in compression, quality, metadata, channel support and compatibility with players and editing software.
What to know about AIFF
Audio encoding
AIFF uses format-specific rules to store or compress sound.
Quality and size
Bit rate, sample rate, bit depth and compression influence both fidelity and file size.
Metadata
Track titles, artists, artwork and other tags may be supported depending on the format.
Compatibility
Support for AIFF varies across browsers, devices, editors and media players.
How AIFF conversion works
Converting AIFF decodes the source audio and encodes it with the destination format's codec and selected quality settings.
Lossy conversion cannot restore detail already removed from the source, so keep the original when quality matters.
mp3.now accepts AIFF as input and can also create AIFF output.
AIFF compatibility and software support
Check that the target player or editing application supports AIFF before choosing it for delivery.
MP3 remains a practical fallback when broad playback compatibility is the priority.
