About FLAC to MP3

FLAC is lossless but large. MP3 copies take a fraction of the space and play on every phone, car stereo, and old player.

Encoded with LAME at the bitrate you choose; 256–320 kbps is a sensible choice for music from a FLAC source. Tags may not all carry over.

The FFmpeg engine (about 31 MB) downloads the first time you convert and is then cached by your browser. Files up to about 100 MB are supported because everything runs in browser memory.

Frequently Asked Questions

Is FLAC to MP3 conversion free?

Yes. No signup, watermark, or daily cap.

Is my file uploaded?

No. FFmpeg runs in this tab as WebAssembly. Only the engine files are downloaded.

Why is it slow on my phone?

Encoding runs on a single CPU thread in the browser. Desktops are much faster; short clips work best on phones.
