Why convert WAV to FLAC?
Converting from WAV Audio (WAV) to FLAC Audio (FLAC) is a common need in daily workflows. Whether you need a more compatible audio format, smaller file sizes, or higher fidelity, choosing the right audio format matters for every project.
With Metric Converter, the WAV to FLAC conversion runs in your browser using FFmpeg.wasm. The audio file is not uploaded to our server. The first conversion downloads the FFmpeg engine (~25MB), and processing time depends on the file and device.
