- Large file sizes due to uncompressed audio data storage
Technical Details
Audio Codec Transformation
Convertify decodes AAC’s Advanced Audio Coding format and re-encodes to AIFF’s uncompressed Linear PCM. This process expands compressed audio data back to full resolution, though it cannot restore data lost during original AAC encoding.
Sample Rate & Bit Depth Handling
The converter maintains original sample rates (typically 44.1kHz or 48kHz) and expands bit depth to 16-bit or 24-bit Linear PCM. AIFF’s chunk-based structure stores audio data alongside metadata in Apple’s native format.
Metadata Preservation
Important audio metadata including track titles, artist information, and album data is transferred from AAC’s ID3 tags to AIFF’s compatible metadata chunks, ensuring your music library organization remains intact.

Frequently Asked Questions
Will converting AAC to AIFF improve the audio quality?
Converting AAC to AIFF won’t restore audio data lost during the original AAC compression, but it will create an uncompressed file that’s better suited for editing and won’t suffer further quality loss. The AIFF file will sound identical to the source AAC but in an uncompressed format.
How much larger will AIFF files be compared to AAC?
AIFF files are typically 8-10 times larger than AAC files. A 4MB AAC file will become approximately 35-40MB as AIFF due to the uncompressed Linear PCM audio data. The exact size depends on the original sample rate and bit depth.
Can I convert AAC files with DRM protection?
No, Convertify cannot convert DRM-protected AAC files from iTunes or other protected sources. Only DRM-free AAC files can be converted. You can convert AAC files you’ve created yourself or purchased as DRM-free downloads.
Will metadata like song titles and artist names be preserved?
Yes, Convertify transfers important metadata from AAC files to the AIFF format, including track titles, artist names, album information, and other compatible tags. Your music library organization will remain intact after conversion.
What sample rates and bit depths does the converter support?
The converter supports all standard AAC sample rates (8kHz to 96kHz) and will output AIFF files at matching sample rates with 16-bit or 24-bit Linear PCM encoding, depending on the source AAC file’s characteristics.
Can I convert multiple AAC files to AIFF simultaneously?
Yes, with Convertify’s batch processing capabilities, you can convert hundreds or thousands of AAC files to AIFF format in a single operation. Simply drag and drop multiple files or entire folders for bulk conversion.
Do I need an internet connection to convert AAC to AIFF?
No internet connection is required. Convertify processes all AAC to AIFF conversions locally on your Windows computer, ensuring complete privacy and allowing you to work offline with sensitive audio files.
Which professional audio software works best with AIFF files?
AIFF files work excellently with Pro Tools, Logic Pro, Cubase, Adobe Audition, and most professional DAWs. Apple’s native audio applications particularly favor AIFF due to its origin as Apple’s standard uncompressed audio format.
