FLAC Converter supports all the official FLAC compression levels from 1 to 8 and additionally includes uncompressed FLAC format. Conversions between all lossless formats and FLAC format are performed with bit-to-bit exact accuracy. Conversions from FLAC format to lossy formats such as MP3, M4A, Opus, Vorbis are performed in highest sample accuracy (32-bit floating point) to make sure there is absolutely best audio quality when the files are converted from high resolution (e.g. 24-bit) FLAC files. FLAC Converter includes very high quality sample rate converter in case the resampling is needed. Changing the sample rate e.g. from 96 kHz to 44.1 kHz is performed with perfect audio quality.


Batch convert FLAC files to MP3 with highest audio quality, keep all metadata tags on conversions. Music conversions from 24-bit FLAC to MP3 is processed with 32-bit floating point precision for highest audio quality.

Convert FLAC+CUE (Cue Sheet) to individual files

FLAC Converter has full support to convert from FLAC+CUE (Cue Sheet). FLAC Converter can split the tracks from Cue Sheet (CUE+FLAC) and encode the tracks into the individual audio files. E.g. FLAC+CUE to multiple MP3 files can be done quickly by running multiple parallel converters (up to 64).

Convert DSD to FLAC

FLAC Converter can convert all DSD audio files formats, DSF (DSD Stream File), DFF (DSDIFF, including DST compressed), WavPack DSD to high quality FLAC format. E.g. conversion from DSD64 to 24-bit FLAC 96kHz with highest fidelity audio quality.

Convert SACD to FLAC

FLAC Converter can convert stereo and multi-channel SACD ISO files to high quality FLAC files. It supports multi TOC (stereo + multichannel) SACD ISO image files. Multi-channel SACD ISO can be converted to 5.1 FLAC or downmixed to Stereo FLAC files.

Metadata services


All audio codecs are included with the software. There is no need to download codecs from other sources.

All audio codecs operate in high resolution audio (32-bit floating point or better accuracy). Hi-res accuracy ensures that there is no additional quantization or dithering noise when converting from hi-res source (e.g. 24-bit FLAC to MP3) or when transcoding between lossy audio formats (e.g. MP3 to AAC).
