FLAC to MP3 Converter

FLAC is lossless, so converting to MP3 does discard some audio data — that's how lossy compression works. However, at 256–320 kbps, most people cannot tell the difference in blind listening tests. Since FLAC preserves the full source quality, converting from FLAC produces the best possible MP3.

FLAC uses lossless compression — it reduces file size by about 50–60% while preserving every bit of the original audio. MP3 uses lossy compression, reducing size by 90%+ but permanently removing some audio data that the encoder considers inaudible. FLAC is ideal for archival and critical listening; MP3 for everyday portable use.

Many older devices, car stereos, and basic media players don't support FLAC. Apple devices gained FLAC support only with iOS 11 and macOS High Sierra. Some Bluetooth headphones and smart speakers also lack FLAC compatibility. Converting to MP3 guarantees playback on any device.

320 kbps — maximum quality, the best MP3 can offer. Since FLAC preserves the original, 320 kbps gives you the highest fidelity MP3 possible. 256 kbps — excellent quality with slightly smaller files. 192 kbps — good for general listening. Convertio uses high-quality encoding by default.
