Omni-Converter

M4B to FLAC Converter

Convert M4B audio files to FLAC directly with Omni-Converter. Lossless compression is available without changing quality. Files use the same Omni-Converter processing engine.

How this conversion route works

Choose a M4B file. Omni-Converter is already set to create FLAC, and you can adjust compression when the output format supports it.
