Convert to FLAC

FLAC is an open-source lossless audio codec. Compressed output is 50-70% the size of WAV and decodes bit-identically to the original samples. This group converts WAV and MP3 to FLAC — 2 conversion directions.

WAV to FLAC keeps full quality at a smaller size, ideal for music library archiving. MP3 to FLAC only changes the encoding and cannot restore detail lost to lossy compression. Tag metadata is stripped; sample rate and channel adjustment are supported.

WAV

WAV→FLAC

Encodes WAV PCM to FLAC lossless compression, cutting size by 40–60% with bit-identical decoding for long-term music archiving.

MP3

MP3→FLAC

Re-wraps decoded MP3 in a FLAC container without adding new lossy compression, unifying library format and metadata handling.
