Pick a strength preset to control how much smaller the output WAV is.
Compression strength
WAV is uncompressed by definition, so “compression” here means lowering the sample rate, bit depth or channel count. Stronger presets sound noticeably worse — best reserved for voice notes.
About WAV compression
WAV is uncompressed audio — every sample stored at full quality. That makes it perfect for studio masters and audio editing, but it also makes WAV files large: a typical 3-minute song lands around 30 MB. When you don't need pristine quality (a voice memo, a draft mix, a sound effect), shrinking the WAV is the right move.
Because WAV doesn't have a built-in compression algorithm like MP3 or OPUS, we shrink it by reducing what's stored: sample rate (how many measurements per second), bit depth (how precise each measurement is), and channels (mono vs stereo). The Low preset just trims the bit depth a touch. The Medium preset halves the sample rate to 22 kHz. The Strong preset is voice-grade — 11 kHz, 8-bit, mono — and produces files about a tenth of the original size.

WAV compression FAQ
Why not just convert to MP3?
Sometimes the destination wants a real WAV (older audio editors, embedded systems, certain video editors). When that's the case, this tool keeps the format but shrinks the file.
How much smaller does each preset get?
Low usually shaves a few percent. Medium is roughly half the size. Strong is around 90% smaller — voice-grade, intelligible but unmistakably degraded for music.
Will Strong sound bad?
For music, yes — 8-bit / 11 kHz is muffled and noisy. For voice memos and dialog, it's perfectly intelligible and tiny. Pick Strong only when size matters more than fidelity.
Can I compress non-WAV files?
This tool is WAV-only. For other formats use the main converter (drop in any audio, get MP3 / OPUS / AAC out).
Is my file kept private?
Yes. We don't analyse or index your audio, and processed files are deleted within 24 hours.
