Quick answer: To convert FLAC to MP3, add your FLAC files here, keep 320 kbps (or pick 256 or 192) and download the MP3s, or a ZIP of all of them. A 320 kbps MP3 is roughly a third of the FLAC size and sounds the same to most listeners. The files are converted in your browser, not uploaded.
FLAC keeps CD quality but many car stereos, older players and apps will not play it, and the files are large. Convert whole albums to 320 kbps MP3 in one go.

Sizes: FLAC vs MP3
FLAC is lossless compression of CD audio, typically 700 to 1,000 kbps, so an album is about 250 to 400 MB. MP3 is lossy but at high bitrates the difference is very hard to hear:
| Format | Bitrate | One 4-minute song | A 45-minute album |
|---|---|---|---|
| FLAC (CD quality) | about 900 kbps | about 27 MB | about 300 MB |
| MP3 320 kbps | 320 kbps | 9.6 MB | 108 MB |
| MP3 192 kbps | 192 kbps | 5.8 MB | 65 MB |
Keep your FLAC files
Converting to MP3 throws away detail that cannot be restored, so treat the MP3s as copies for devices and keep the FLAC files as your archive. Converting FLAC to MP3 and back to FLAC does not bring the quality back. High-resolution FLAC (24-bit, 96 kHz) is converted to standard MP3 at 44.1 or 48 kHz, which is all MP3 supports.
Sharing the lossless album itself with someone? Send the FLAC files with a link, free up to 20 GB, instead of converting them.
Encoded with LAME, on your device
The MP3s are made with LAME, the reference MP3 encoder, running in your browser. Nothing is uploaded, so converting a large collection costs no upload time. Track tags such as artist and title are not copied into the MP3s; add them in your music player afterwards if you need them.

Frequently asked questions
What bitrate should I use for FLAC to MP3?
320 kbps keeps the most quality and is the usual choice when converting from lossless. 192 or 256 kbps saves space and still sounds good on phones and in the car.
Can I convert a whole album at once?
Yes. Add all the tracks, convert them together and download a ZIP.
Will the MP3 sound worse than the FLAC?
Technically it loses detail, but at 320 kbps most people cannot hear the difference in a blind test. Keep the FLAC files as your master copies.
Are my files uploaded?
No. They are converted in your browser on your device.
