No. Everything runs in your browser - your file never leaves your device. How this is verifiable
AIFF (Audio Interchange File Format) is Apple's 1988 counterpart to WAV - an uncompressed PCM container that remains the standard export format in Logic Pro, GarageBand and many professional studios to this day. Like WAV, it is excellent for editing but poor for sharing: the files are huge.
The tool decodes the raw PCM samples from the AIFF file and encodes them with libmp3lame to MP3 at the chosen bitrate. That turns a finished, mixed studio export into a small file, playable anywhere, ready to share or upload.
Since AIFF itself compresses nothing, the chosen MP3 bitrate alone decides the quality - for a finished mix, 256 or 320 kbps pays off. Everything runs entirely locally in the browser, your finished master never leaves your device.

Limitations: The conversion to MP3 is lossy - for archiving or further editing, the AIFF original remains the better source. One file per run.
No, the conversion runs entirely locally in the browser.
Both store uncompressed PCM; AIFF comes from Apple and orders the bytes big-endian, WAV from Microsoft/IBM little-endian - sonically identical.
Yes, for archiving or further mixing, AIFF stays lossless - MP3 is meant only for playback/sharing.
Usually from Logic Pro, GarageBand, Pro Tools exports or older Mac music archives.
