Questions

How do I convert MP3 to FLAC?

Drop your MP3 file on this page, or choose it. Anyfile converts it on your device in a moment and the FLAC downloads straight away. To change it first, open it in the audio editor.

Is my MP3 file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several MP3 files at once?

Yes. Drop them together and you get one ZIP with every FLAC inside.
