FAQ

Frequently asked questions

Is quality lost going from AIFF to FLAC?

No. FLAC is lossless, so the full audio quality of the AIFF file is preserved. The file is simply packed more efficiently.

Why convert AIFF to FLAC?

FLAC stores the same audio losslessly but needs far less space than AIFF or WAV. That makes it ideal for a compact, lossless archive.

How much smaller does the file get?

Depending on the material, the file typically shrinks noticeably, often by around half, with no quality loss. The exact saving depends on the audio content.

Do my files stay private?

Yes. By default the conversion runs entirely in your browser. An optional server mode is available only for very large files.
