Convert FLAC to MP3
Drop a FLAC file and get a compressed MP3 back, ready to share, stream, or play on any device. The first time you use this tool the audio engine downloads once (~24 MB); after that the browser uses its cached copy. Your file never leaves your device.
About FLAC to MP3
FLAC (Free Lossless Audio Codec) compresses audio without discarding any detail, so a FLAC file sounds identical to the source but stays large. MP3 takes a different approach: it is a lossy format that discards subtle detail the ear is least likely to notice, which makes the file much smaller. Converting FLAC to MP3 decodes the lossless samples and re-encodes them with libmp3lame at 192 kbps by default; the process is lossy, so some fine detail is permanently removed, but the result is far smaller and plays on virtually any device or platform. Keep your FLAC file if you want to retain a lossless master.
Is it private?
Yes. The converter is WebAssembly and browser APIs running on your own machine. Nothing is uploaded, stored, or seen by us. There is no server to send files to.
Frequently asked questions
- Why is my MP3 smaller than the FLAC?
- FLAC is lossless: it compresses without throwing anything away, so the files stay fairly large. MP3 is lossy — it discards subtle detail the ear is least likely to notice — so a FLAC track typically shrinks to roughly a third to a fifth of its size at 192 kbps.
- Is converting FLAC to MP3 lossy?
- Yes. FLAC preserves every sample; encoding to MP3 permanently removes some fine detail to make the file smaller. The trade is a far more compact file that plays on virtually any device or app. Keep the original FLAC if you want the archival copy.
- Are my files uploaded to a server?
- No. The conversion runs on your device using WebAssembly and browser APIs. Your file is never sent anywhere. The first time you use the tool the audio engine downloads once (about 24 MB); after that the browser uses its cached copy.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, convert it, and download the result.
