Frequently Asked Questions
Why are WAV files so large and how does this tool compress them?
Standard WAV files store raw, uncompressed pulse-code modulation (PCM) audio data running at 1,411 kbps (16-bit, 44.1 kHz stereo), which takes approximately 10MB per minute. Our tool compresses WAV audio by transcoding the sound waves using psychoacoustic models that remove imperceptible frequencies, shrinking the file size by up to 90% while retaining human-audible clarity.
Are my private WAV recordings uploaded to your servers?
No. The WAV compression engine runs 100% locally on your computer or phone using WebAssembly. Your audio files never leave your device, ensuring total confidentiality for personal voice recordings, commercial tracks, and confidential interviews.
Can I keep the WAV format, or should I convert to MP3?
You can choose either option. If you select MP3 or OGG output, you will achieve the maximum size reduction (~90% savings) with universal compatibility across all devices and media players. If you select WAV output, our tool optimizes the audio frames while preserving the .wav container.
What bitrate should I choose for compressing music vs spoken voice?
For spoken audio, podcasts, and interviews, 64 kbps or 96 kbps provides crystal-clear vocal clarity with maximum size reduction. For music tracks, acoustic recordings, or DJ sets, we recommend 128 kbps for balanced web sharing, or 192 kbps β 256 kbps for audiophile listening.
Is there a limit on file size or track duration?
You can compress WAV audio files up to 200MB directly in your browser. There are no artificial duration limits, subscription fees, or daily conversion caps.
