Convert AMR to FLAC — Free Online Converter

AMR captures voice at telephony-grade quality using aggressive lossy compression standardized by 3GPP. FLAC (Free Lossless Audio Codec) is the open-source standard for lossless audio, compressing PCM data to roughly 50-60% of its original size with no quality loss at all. Converting AMR to FLAC creates a lossless archival copy of the decoded voice recording that any operating system or media player can handle.

FLAC is the gold standard for lossless audio on non-Apple platforms. Android, Linux, Windows (via built-in codec), and web browsers all support FLAC natively. If you need to preserve a voice recording exactly as the AMR decoder outputs it — for legal evidence, archival, or further editing — FLAC is the most widely compatible lossless option. It also compresses the PCM data, so files stay smaller than WAV.
