Frequently asked questions
Is converting FLAC to AAC free?
Yes. There is no sign-up, no watermark and no limit on the number of files.
Are my files uploaded?
No. Everything runs in your browser, so your files are never uploaded to a server. That also makes it fast, because nothing has to travel over the network.
Will I lose quality converting FLAC to AAC?
AAC stores the result with some loss. With the default settings the difference is hard to notice, and you can raise the quality if you need to.
Can I convert several files at once?
Yes. Drop as many FLAC files as you like. They are converted one after another and you can download them individually or as a ZIP.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device's memory, since the conversion runs locally.
