How WAV to AIFF Conversion Works

The Waveform Audio File Format format stores uncompressed PCM audio samples at full bit depth, giving lossless fidelity at the cost of large file sizes. Converting to AIFF produces a document file that stores data in the AIFF format. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. This makes AIFF the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.

Frequently Asked Questions

Everything you need to know about converting WAV to AIFF

No—both WAV and AIFF commonly store uncompressed PCM, so the conversion is typically lossless when the tool maps PCM settings directly.
Usually not. Since both formats are typically uncompressed PCM containers, AIFF size is often similar to the WAV, with differences mainly from metadata and chunk structure.
AIFF can represent standard PCM configurations, so most WAV bit depths and sample rates transfer cleanly; extreme or unusual formats may require normalization.
Many macOS and AIFF-oriented workflows import AIFF smoothly, while some legacy pipelines expect AIFF containers; converting can prevent import or metadata issues.
