Why convert FLAC to MP3
FLAC is lossless: it keeps every detail of a CD or studio master, but a single album can take 300 to 500 MB. Many car stereos, older iPods and MP3 players, and apps like iTunes and Apple Music don't play FLAC at all.
A 320 kbps MP3 made from a FLAC is about a third of the size and sounds identical to nearly everyone. Keep the FLAC as your archive and put the MP3 on devices.
What happens to your FLAC
FFmpeg in WebAssembly decodes the FLAC and encodes it with the LAME MP3 encoder. Text tags such as title, artist and album are copied. Embedded cover art is not copied.
Hi-res FLAC files (24-bit, 96 or 192 kHz) work too; MP3 supports up to 48 kHz, so they are converted down, which makes no audible difference.

Frequently asked questions
Is my file uploaded anywhere?
No. The conversion runs in your browser with a WebAssembly build of FFmpeg. Your file is read from your device and the result is saved back to it; nothing is sent to our servers.
Will I hear a difference between FLAC and 320 kbps MP3?
Almost nobody can in blind tests on ordinary equipment. Keep the FLAC if you want a perfect archive or plan to convert again later.
Is the album art kept?
Text tags are copied, but embedded cover art isn't. Most players fetch the artwork again from the album tags.
Can I convert a whole album at once?
One track at a time. After each conversion, Process another file keeps your settings.
Should I choose M4A instead?
For Apple Music and iPhone, M4A at 256 kbps is as good as MP3 at 320 kbps and slightly smaller.
How large a file can I convert?
Files up to 4 GB and 4 hours long on a computer, or 2 GB and 2 hours on a phone. The video is read in pieces rather than loaded into memory, so large recordings work; only the audio file being written has to fit in memory.
