Upload a WAV file and shrink its size. WAV audio is uncompressed, so it shrinks by lowering the sample rate and bit depth.
Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.
WAV is uncompressed, so this tool shrinks it by lowering the sample rate and bit depth: fewer samples, smaller file, still a standard WAV. Halving the sample rate roughly halves the size.
That approach genuinely reduces fidelity, so it suits voice recordings and drafts more than finished music.
If you need small but lossless, convert WAV to FLAC: about half the size, zero loss, still pro-grade. If you need very small and lossy is fine, WAV to MP3 or M4A shrinks by around 90 percent. Keep this tool for cases where the output must remain WAV.
