AIFF (.aiff) · Max 20 MB
Traditional online converters upload your file, process it on a remote server, and send it back. That's slow, insecure, and wasteful. AudioUtils eliminates the upload entirely.
The converter uses WebAssembly to run a compiled audio engine in your browser tab. It reads your file locally, converts it locally, and saves the result locally. The network is never involved.
This matters for sensitive audio. Unreleased music, legal recordings, private conversations. With AudioUtils, your files stay yours. Both AIFF and WAV are lossless. This conversion preserves every sample. No quality is lost.
Frequently Asked Questions
Is AIFF to WAV lossless?
Yes, 100%. Both formats store uncompressed audio. Converting between them changes only the container, not the audio data.
Why not just use AIFF everywhere?
WAV has broader support, especially on Windows and in cross-platform tools. AIFF is primarily a Mac format.
Are the file sizes the same?
Nearly identical. Both store uncompressed audio. You might see a tiny difference due to header/metadata formatting, but audio data size is the same.
Which format supports better metadata?
AIFF has better built-in metadata support. WAV traditionally has limited metadata, though modern tools handle this well with ID3 tags in WAV.
