Turn FLAC library files into 320 kbps MP3 listening copies, with tags and cover art carried across, batch conversion for albums, and your FLAC masters kept exactly as they are.

FLAC is where a serious music library lives: lossless, tagged, artwork and all. Converting FLAC to MP3 makes the portable copy, the one for the phone, the car and the upload form, while the FLAC stays home as the master. This converter defaults to 320 kbps because this audience is quality-first by definition, and it treats your tags and cover art as requirements, not luck.
Metadata is a build requirement on this pair, so it is worth saying plainly. Your title, artist, album and cover picture are mapped into the MP3 as proper ID3 tags, including the embedded picture block that FLAC uses, which becomes the MP3’s cover art. A conversion that strips the artwork off an album has failed at the job even if the sound is fine, and this one is wired not to.
1. Drop the FLAC files into the box. Albums arrive in folders, so up to 10 convert in one run.
2. Keep 320 kbps for the best listening copy, or pick VBR for smaller files at near-identical quality.
3. Press Convert to MP3 and download the ZIP.
MP3 tops out at 48 kHz, so a 96 kHz or 192 kHz FLAC is resampled down during conversion, and the result line says so with the real numbers: your 96 kHz file became 48 kHz, the highest MP3 holds. Nothing about that is audible in normal listening, but you are entitled to know it happened. Bit depth above 16 is dithered down by the same path. The shrink math: FLAC from CD rips runs about 700 to 1000 kbps, so a 320 kbps MP3 lands near a third of the size, varying with the music itself.
The engine note: the first job downloads about 31 MB of encoder files once, your browser caches them, and your audio never leaves the device.
The master rule, printed as plainly as it deserves: keep the FLAC files. This MP3 is a listening copy. Storage is cheap and re-ripping or re-buying a collection is not, and deleting the lossless master to save space is the one irreversible mistake available on this page. Tag honesty too: tags and art are carried where the two formats share fields, which covers the standard fields completely. Exotic custom tags may not have an MP3 home. Apple note: iTunes and Apple Music do not play FLAC at all (ALAC is Apple’s lossless route), another reason this conversion exists. Other pairs live on the audio converter, and the full set is in the audio tools collection.
Nobody converts one FLAC. They convert the new rip, the box set, the folder from a friend. Batch mode with one shared setting and a single ZIP download is the main road on this page, not an extra. Set the rate once, drop the album, take the folder of MP3s.
Yes. The embedded picture in the FLAC is mapped into the MP3 as its cover art, and the standard text tags (title, artist, album, year, genre) are carried with it.
FLAC from CD rips runs about 700 to 1000 kbps, so a 320 kbps MP3 lands around a third of the size. The exact figure depends on the music: dense and loud compresses less than sparse and quiet.
MP3 caps at 48 kHz, so higher rates are resampled to 48000 Hz during conversion, and the result line tells you the real numbers. Your FLAC master is untouched.
No. The MP3 is a listening copy made for portability. The FLAC is the master you can convert from again, forever, at any future setting. Deleting it is the one move on this page you cannot undo.
Because this pair’s audience keeps lossless files on purpose. 320 kbps is the closest MP3 gets to the source, and VBR is offered when you prefer the smaller file.
No. Apple’s lossless format is ALAC. That is one reason FLAC libraries get converted to MP3 for Apple destinations, and the audio converter can also produce M4A.
