Question 1

Will going from AIFF to FLAC make it sound better?

Accepted Answer

No — and you don't lose anything either. Both AIFF and FLAC keep the sound exactly as it was. You are just swapping the wrapper. The file size and the apps that can play it may change; the sound itself does not.

Question 2

Why would I want to change AIFF to FLAC?

Accepted Answer

Different phones, speakers, and apps prefer different formats. Saving as FLAC can make a song play where AIFF won't. A perfect-quality copy of the original. Great for music libraries you want to keep for years.

Question 3

Is it really free?

Accepted Answer

Yes. No accounts, no waiting, no watermarks, no file-size limits. The site shows ads to pay the bills — the converter itself is fully unlocked for everyone.

Question 4

Where do my files go?

Accepted Answer

Nowhere. Your songs stay on your own phone or computer the whole time. Nothing is sent to any server. You can even use the site offline once it has loaded once.

Question 5

How big can a file be?

Accepted Answer

Up to 500 MB per file. That is enough for several hours of music. If you have something much bigger, like a long audiobook, a desktop program will handle it more easily.

Question 6

Why is the first conversion slow?

Accepted Answer

The first time you use the site, your browser downloads the small piece of software that does the work — about 30 MB. After that, every conversion starts straight away.
