Frequently Asked Questions

Both FLAC and WAV are lossless, but WAV is uncompressed and more universally compatible with DAWs (Digital Audio Workstations) and audio editing software. Some older programs don't support FLAC but all professional audio tools support WAV.

No! Both FLAC and WAV are lossless formats. FLAC is compressed lossless, WAV is uncompressed lossless. Converting between them is like unzipping a file—you get the exact original data with zero quality loss.

Choose 'Original' to preserve the source sample rate and bit depth. This maintains the exact quality of your FLAC file. Only change sample rate if you need specific compatibility (44.1kHz for CD, 48kHz for video).

WAV files are typically 2-3x larger than FLAC since FLAC uses lossless compression. A 20MB FLAC file becomes 40-60MB as WAV. The extra size is just decompression—quality is identical.

FLAC is better for archiving. It's lossless like WAV but 50-70% smaller, has better metadata support, and includes error detection. Keep archives in FLAC, convert to WAV only when needed for editing or compatibility.

Currently, this tool processes one file at a time for optimal browser performance. For batch conversion, process files sequentially. Each conversion maintains your selected sample rate settings.

WAV has very limited metadata support compared to FLAC. Basic information may transfer, but WAV doesn't support embedded album artwork or detailed tags. You may need to re-add metadata in your music library software.

Use WAV for editing. While FLAC is lossless, most professional DAWs work faster with uncompressed WAV. After editing, you can save back to FLAC for efficient storage if desired.

Both are uncompressed lossless formats. WAV is the Windows standard, AIFF is the Mac standard. They're functionally identical in quality. WAV has broader compatibility across platforms and software.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your audio files never leave your device, ensuring complete privacy.
