FLACMP3
Turn a lossless FLAC archive into a compact, portable MP3 that streams and plays everywhere.
FLAC (Free Lossless Audio Codec) compresses audio without discarding any data — it typically squeezes a file to 50–60% of the original WAV size while remaining bit-perfect, so a decoded FLAC is identical to the source master. That fidelity makes FLAC ideal for archiving, but it is large and not supported by every device. MP3 trades away the lossless guarantee: libmp3lame applies psychoacoustic compression to reach roughly a tenth of the size, playable on essentially anything. Converting FLAC to MP3 is a lossless-to-lossy step — irreversible, because the encoder permanently removes detail. Keep the FLAC as your archival copy and use the MP3 as a lightweight distribution version for phones, streaming, and players that lack FLAC support.
Convert FLAC to MP3 on the canvas
Drop your file onto a Brainy Canvas board, connect the converter node, and download the result. New accounts get free starter credits — enough for roughly 100 audio conversions — with no card required.

Attach the Audio Converter
Connect the File node to an Audio Converter node and select MP3; FFmpeg decodes the FLAC and encodes with libmp3lame server-side.

Download the MP3
When the sandbox finishes, download the .mp3 — a portable copy of your lossless source.
