About WAV Audio
WAV (Waveform Audio File Format) stores raw, uncompressed PCM audio — what you record is exactly what you get, with zero quality loss. Developed by Microsoft and IBM in 1991, it's the standard for professional audio editing, music production, and any workflow where lossless quality is non-negotiable. The trade-off is size: one minute of CD-quality WAV is roughly 10MB.

Why privacy matters for file conversion
Most online converters upload your files to remote servers where they may be scanned, stored, or shared. This tool is different — the conversion runs in your browser via WebAssembly or the WebCodecs API. Your files stay on your device. Always.

Frequently asked questions
FLAC compresses audio losslessly to about 50-60% of WAV size with zero quality loss. Use WAV for active editing projects (DAWs prefer it), and FLAC for archival and distribution.
Yes, completely free with no file limits. The conversion engine runs directly in your browser — we have zero server costs for processing, so we can offer it at no charge.
Your file never leaves your device. The conversion engine runs 100% in your browser using WebAssembly or the WebCodecs API. We have no access to your files — no uploads, no logs, no data collection whatsoever.
On desktop browsers (Chrome, Firefox, Edge) files up to 500 MB convert reliably. On Safari (macOS) the practical limit is around 200 MB. On iPhone and iPad, keep files under 50 MB — iOS enforces tight memory limits for browser-based processing.
On your first visit, the browser downloads the conversion engine (24–50 MB depending on which backend is used). This is cached locally, so subsequent conversions load much faster.
Chrome, Edge, and Brave use hardware-accelerated WebCodecs when the format is supported — this is 5–10× faster than software encoding. For unsupported formats the tool falls back to ffmpeg.wasm, where Firefox typically performs best.
