Frequently Asked Questions

Q: How much smaller will the MP3 be?

A: WAV is an uncompressed format. Converting to MP3 (e.g., at 192kbps) typically reduces the file size by 80-90%.

Q: Will I lose audio quality?

A: MP3 is a "lossy" format, meaning some inaudible data is removed. However, at higher bitrates (256kbps+), the difference is indistinguishable to the human ear.

Q: Is this tool secure?

A: Yes, the audio processing is done entirely in your browser using WebAssembly. No audio is ever uploaded.
