How to use it
- Drop your FLAC files (a whole album works).
- Choose 256 or 320 kbps for music you care about.
- Click Convert to MP3 and download the ZIP.
FLAC vs. MP3
FLAC is lossless: it compresses audio to roughly half the size of WAV without throwing anything away. It's the format of choice for archiving CDs and for hi-res downloads, but files are large (often 25–35 MB per song) and some cars, players and apps don't play them.
MP3 is lossy and much smaller: a 4-minute song at 320 kbps is about 9.6 MB, at 192 kbps about 5.8 MB. Converting FLAC to MP3 at 256 or 320 kbps keeps the sound very close to the original. Keep your FLAC files as the master copy; you can always make new MP3s from them, but not the other way around.
Albums, file names and privacy
Select all the tracks of an album at once. Each MP3 keeps its FLAC file name, and the tracks come back together in one ZIP. Tags such as artist and album title are not copied into the MP3s, so you may need to re-tag them in your music app.
The conversion runs in your browser, so nothing is uploaded. For other formats, the general MP3 converter accepts almost any audio or video file.
Frequently asked questions
What bitrate should I use for FLAC to MP3?
320 kbps for the best MP3 quality, 256 kbps for a good balance, 192 kbps if space matters.
Will metadata and album art be kept?
No. The MP3s contain the audio only; add tags and cover art afterwards in your music app.
Does it work with hi-res (24-bit) FLAC?
Yes. The audio is decoded and encoded as a standard 44.1 kHz MP3.
