How to Convert to MP3

1
Add your FLAC files
Up to 200 MB each and twenty at a time, enough for a full album in one go.
2
Pick 320 kbps or switch to variable
320 is the default here because the source is lossless. Variable quality 0 gives a similar result in a smaller file.
3
Click Convert and download
Artist, album, track numbers and the embedded cover all travel with the file.

Why the default here is 320 and not 192

Every other converter on this site defaults to 192 kbps, which is the point where most listeners stop hearing a difference. This one defaults to 320 for a specific reason: people who keep FLAC keep it on purpose. Going to the trouble of a lossless library and then converting it at a middling bitrate loses the thing the library was for. 320 kbps is the highest the MP3 format allows and the closest it comes to the source; in blind listening tests it is very rarely distinguished from lossless on ordinary equipment. If size matters more than that last margin, variable bitrate at quality 0 averages around 245 kbps and is extremely close, or 192 kbps halves the file again for portable listening.

What is actually being lost

FLAC compresses losslessly: it stores the original samples in less space by predicting them, and decoding returns the exact bytes that went in. Converting to MP3 is the first time anything is discarded: frequencies masked by louder sounds nearby, detail above the range most people hear, and stereo information where the two channels barely differ. That loss is permanent. The practical consequence is simple: keep the FLAC. This conversion is for the copy that goes on a phone, in a car or to someone whose player will not read FLAC, not for replacing the library.

Album art and tags come across whole

FLAC files carry their metadata in Vorbis comments and usually an embedded picture block, and a properly tagged library has artist, album, track number, year and cover on every file. All of it is copied into the MP3 as ID3v2.3 tags with the cover as an attached picture, which is what music players, phones and car stereos read. This matters more for FLAC than for any other source here, because FLAC libraries are the ones most likely to be carefully tagged in the first place, and losing that on conversion would mean re-tagging an album by hand.

Sample rates above CD quality

High-resolution FLAC at 96 or 192 kHz is common in download stores. MP3 does not go above 48 kHz, so those files are resampled during conversion. That is not a defect in the conversion; it is the format's ceiling, and the audible consequence is essentially nil, since the discarded content sits far above human hearing. Choosing 44,100 Hz explicitly gives the most compatible result if the file is going somewhere old.

Your library stays on your machine

The FLAC is decoded and encoded to MP3 by the LAME encoder, running as WebAssembly in this tab, and the tags and cover are carried across here too. The engine downloads once into your browser cache, and after the first use the page works offline. No file, tag or cover reaches a server, and there is no account.

Frequently asked questions

How much smaller will the files be?

Four to six times at 320 kbps, depending on how well the music compressed as FLAC in the first place. A 30 MB track typically lands around 6 to 7 MB.

Is 320 kbps really necessary?

For most listening, 192 is enough. 320 is the default here because a lossless source deserves the format's ceiling, but the choice is yours, and variable quality 0 is a good middle ground.
