Compress WAV files
Upload a WAV file and shrink its size. WAV audio is uncompressed, so it shrinks by lowering the sample rate and bit depth.

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.
Some transcription services, phone systems, and legacy tools accept only WAV input. Lowering its sample rate is then the way to cut upload sizes.
It removes the highest frequencies first. Speech survives this well; music loses sparkle. 16 kHz mono is a common target for voice pipelines.
