FAQ

Frequently asked questions

Does AIFF improve the quality?

No. AIFF is uncompressed, but the detail lost during MP3 encoding does not return. The AIFF file sounds like the MP3, just without compression.

When does this conversion make sense?

When you want to keep editing an MP3 in an Apple DAW like Logic Pro, which prefers working with uncompressed AIFF.

Why does the file get so large?

Because AIFF is uncompressed, it takes several times the MP3's size. That extra size holds no new sound information, though.

Are my files uploaded?

No, conversion runs directly in your browser by default. For very large files there is an optional server mode.
