Convert lossless FLAC files into compact M4A files that slot neatly into Apple libraries. Conversion runs right in your browser, so your music is not uploaded by default.
In “Local” mode your file never leaves your device. No uploads, no server – ideal for sensitive recordings.
Pick “Local” for full privacy or “Server” for very large files and every format.
No sign-up, no queue, no watermark. Choose a file, convert, download.
Yes, a little. FLAC is lossless while M4A with AAC is lossy, so some detail is removed during encoding. At higher bitrates this is hard to hear.
M4A is much smaller and plays seamlessly on iPhones, in iTunes and Apple Music. That lets your music fit comfortably on mobile devices.
Existing metadata such as title, artist and album is carried over into the M4A where possible, so your library stays tidy.
No, conversion runs locally in your browser by default. For very large files there is an optional server mode.
