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.

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.
