Method 2: FFmpeg (recommended for batch and precision)
ffmpeg -i input.flac output.wav. FFmpeg decodes FLAC to PCM and writes WAV. For 24-bit audio: ffmpeg -i input.flac -acodec pcm_s24le output.wav. For 16-bit: ffmpeg -i input.flac -acodec pcm_s16le output.wav. Batch: for f in *.flac; do ffmpeg -i "$f" "${f%.flac}.wav"; done

Method 4: dBpoweramp (Windows, paid but trial available)
dBpoweramp is the gold standard for batch audio conversion. Drag FLAC files → set output format to WAV → Convert. dBpoweramp verifies audio quality during conversion and can batch-convert thousands of files while preserving folder structure.
Why convert FLAC to WAV?
FLAC is the better format for storage — it's 30-60% smaller than equivalent WAV at identical quality. WAV is the better format for professional audio workflows — virtually every DAW, audio editor, and hardware device accepts WAV natively. Pro Tools historically struggled with FLAC. Logic Pro, Ableton Live, FL Studio, and most DAWs prefer WAV for their session files. If you're building a professional audio production setup, convert your FLAC library to WAV for the working versions and keep the FLACs as your compressed archive.
Your files never leave your device
FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.
