info About this tool
Convert audiophile-grade FLAC files to widely compatible MP3s for your phone or player.

File size: MP3 output at 320 kbps is typically 70–85% smaller than the FLAC source. A 30 MB FLAC becomes approximately 4–8 MB.

Quality: FLAC is lossless; MP3 is lossy. Encoding from FLAC produces the highest-quality MP3 possible since you're starting from a perfect source. Keep your FLAC originals.

help FAQ

What bitrate does the output MP3 use?

We encode at 320 kbps: the highest standard MP3 bitrate. At this setting, most listeners cannot distinguish the MP3 from the lossless FLAC on standard playback equipment.

Should I keep my original FLAC files?

Yes, always. FLAC is your lossless archive. Once you encode to MP3, that quality cannot be recovered. The FLAC is your master; the MP3 is your portable copy.

Is there an audible quality difference?

In double-blind tests, most listeners cannot reliably distinguish 320 kbps MP3 from lossless FLAC. Differences are most audible on high-end playback systems during complex musical passages.

What is the difference between FLAC and MP3?

FLAC is lossless: it preserves every sample of the original recording. MP3 is lossy: it removes audio data that human perception is least sensitive to. FLAC is for archiving; MP3 is for portable listening.
