About FLAC to MP3 Converter
The FLAC to MP3 Converter turns large, lossless FLAC files into compact, universally compatible MP3s right in your browser. It's the easiest way to make a high-quality library portable and playable on phones, cars, and apps that don't support FLAC.
All processing happens locally with the Web Audio API and a JavaScript MP3 encoder, so your FLAC file is never uploaded and your audio stays private.
