AIFF to AAC Converter FAQs
The main reason is to create a convenient, portable version of your audio file. Uncompressed AIFF files are extremely large and not practical for personal music libraries or mobile devices. Converting to AAC dramatically reduces the file size while keeping the sound quality very high, perfect for everyday listening.
At a high bitrate setting, such as 256 kbps or higher, most people using standard headphones or speakers cannot hear a noticeable difference between the original uncompressed AIFF and the converted AAC. The AAC format is very efficient at removing data that the human ear is least likely to miss.
You can expect a massive reduction in file size. A stereo audio file in the uncompressed AIFF format takes up about 10 megabytes per minute. A high-quality AAC file is often about 90% smaller, meaning you can fit roughly ten times more music in the same amount of storage space.
Think of AIFF as the "master copy" used for professional audio recording, editing, and archiving, where perfect quality is required. Think of AAC as the "listening copy" used for distribution and personal music libraries, like in iTunes and on your iPhone, where a balance of great quality and small file size is ideal.
You should choose AAC when you want slightly better audio quality at the same file size. AAC is a more modern and efficient format than MP3, and it's the standard for the entire Apple ecosystem, including iTunes and Apple Music. For use on Apple devices, AAC is the superior choice.
