About the FLAC to MP3
FLAC to MP3 converts lossless FLAC music into MP3 files that are about a quarter of the size and play on every phone, car stereo and portable player. Select your FLAC file, choose a quality from 96 to 320 kbps and keep stereo or use mono. The estimated MP3 size is shown before you start, the finished file can be previewed and downloaded. At 256 or 320 kbps the difference from FLAC is hard to hear on most equipment. The conversion runs in your browser and your music stays on your device.

How to use the FLAC to MP3
- 1Select your FLAC file.
- 2Choose a quality. 320 kbps is closest to the original; 192 kbps is a good balance.
- 3Keep stereo for music.
- 4Press Convert to MP3.
- 5Listen to the preview and download the MP3.
Lossless and lossy
FLAC stores every detail of the original recording in a smaller file, like a zip file for sound. Nothing is lost, so it can be turned back into the exact original. MP3 permanently discards sound that people rarely hear. It makes a much smaller file, but the discarded detail cannot be recovered.
Choosing a bitrate
If you have plenty of space, use 320 kbps, the most any MP3 can offer. If the files are for a phone with limited storage, 192 kbps is a very good compromise. Below 128 kbps, you may hear a thin or watery sound in cymbals and voices.
- 320 kbps: maximum quality
- 256 kbps: near-transparent for most people
- 192 kbps: good for phones
- 128 kbps: acceptable for casual listening
Keep your masters
Do not delete your FLAC files after converting. If you later want a different bitrate, a different format or better equipment, the FLAC can be converted again without further loss. Converting MP3 back into FLAC does not bring the detail back.
Make it fit the player
If your player or car stereo supports AAC, M4A at the same bitrate sounds a little better than MP3. Use the MP3 Converter for other file types, the Audio Compressor to make a file smaller in M4A or OGG, and the Audio Trimmer to cut long intros and endings.
Why it can take a moment
A lossless file contains much more data than an MP3, so decoding and encoding take longer than for small files. Keep the tab open until the progress bar finishes. A computer is much faster than a phone for long tracks.

Frequently asked questions
Why convert FLAC to MP3?
FLAC files are large, often 25 to 40 MB per song, and some phones, cars and players cannot play them. MP3 files are smaller and play everywhere.
Which bitrate is closest to FLAC?
320 kbps is the best MP3 quality, and for most people on normal speakers or headphones it is hard to tell from FLAC. 256 kbps is nearly as good, and 192 kbps is a sensible choice when space matters.
Does converting lose quality?
Yes. FLAC is lossless, MP3 is lossy. Keep your FLAC files as the master copies and use the MP3 versions on portable devices.
What about high resolution FLAC such as 24-bit 96 kHz?
The converter reads them and lowers the sample rate to 48 or 44.1 kHz, which is what MP3 supports. The extra resolution of the original is not kept.
How big will my MP3 be?
About 2.4 MB per minute at 320 kbps, 1.9 MB at 256 kbps and 1.4 MB at 192 kbps, so most songs are 5 to 10 MB.
Can I convert a whole album at once?
This tool converts one file at a time. Open the page again for each track; each takes a few seconds.
Will the tags and cover art carry over?
No. The MP3 has only the sound. Use a tag editor to add the track information and cover again.
Is my music uploaded?
No. It is converted on your device and nothing is sent to a server.
