What is MP3?

What is AIFF?
AIFF is Apple's uncompressed audio format, the Mac counterpart to WAV. It is lossless and large.
Questions
Is the MP3 to AIFF converter free?
Yes, it is free with no sign-up and no watermark. There is no cap on how many files you can convert, and nothing to install.
Do my files get uploaded to a server?
No. The conversion runs entirely in your browser using code that loads onto your device, so the file is read, converted, and downloaded locally. It never reaches us or anyone else.
Will converting improve the quality?
No. AIFF is lossless, but it can only preserve what is already in the MP3; it cannot restore detail that lossy compression has already discarded. The file may also be larger.
