Convert Waveform Audio (.wave) to Audio Interchange File Format (.aiff) online for free. Fast, secure audio conversion with no watermarks or registration.
Conversion settings — add a file to adjust
Upload your .wav file by dragging it into the upload area or clicking to browse.
Choose your output settings. The default settings work great for most files.
Click Convert and download your .aiff file when it's ready.
WAVE and AIFF are both uncompressed PCM audio containers — WAVE uses RIFF (little-endian, Microsoft/IBM origin) while AIFF uses IFF (big-endian, Apple/Amiga origin). Converting between them is a container swap with byte order conversion, preserving all audio data without quality loss. Files using the .wave extension contain identical data to .wav and convert to AIFF in exactly the same way.
This conversion is common in cross-platform professional audio production where macOS-based studios prefer AIFF for its native Apple integration while Windows-based studios produce WAVE files.
Logic Pro, GarageBand, and Final Cut Pro historically prefer AIFF as their native uncompressed format. If you receive WAVE recordings from Windows-based studios, converting to AIFF ensures optimal integration with Apple's professional audio tools, including metadata handling and Finder preview.
Some legacy audio hardware samplers (Akai, E-mu) and archival institutions specifically require AIFF format. Converting WAVE to AIFF also enables adding Apple-specific metadata chunks (like Finder comments) that WAVE does not support.
FFmpeg reads the RIFF/WAVE header to extract PCM format parameters (bit depth, sample rate, channel count) and rewrites the audio data into an AIFF container with big-endian byte ordering. The conversion involves byte-swapping each sample (for 16-bit: swapping the two bytes; for 24-bit: reversing three bytes). No audio processing occurs — the PCM values are mathematically identical before and after byte reordering.
Lossless. WAVE and AIFF both store uncompressed PCM at identical bit depth and sample rate. The conversion is a pure container transformation with byte order change — no audio data is modified, added, or removed. A 16-bit/44.1 kHz WAVE file becomes a 16-bit/44.1 kHz AIFF file of virtually identical size.
