Frequently asked questions
Simple on the outside. Private on the inside.
Are my audio files uploaded to the internet?
No. Your file is read, converted and downloaded from your own browser. The media file itself is not uploaded to our servers.
Does converting to FLAC improve audio quality?
No. Converting can improve compatibility or reduce file size, but it cannot restore audio information already lost in the source file.
Why can the first conversion take a little longer?
Your browser has to prepare the audio engine once. After that, the queue can continue automatically.
