How this WAV to MP3 Converter works

This compression tool converts large, uncompressed WAV audio files into the versatile and widely supported MP3 format.

Users can choose from various bitrate settings, ranging from standard quality for speech to high-quality presets for music, allowing for a tailored balance between file size and sonic fidelity.

Frequently Asked Questions

How much space will I save?
MP3s are usually about 10% of the size of the original WAV file, saving you 90% space.
What bitrate should I choose?
128kbps is standard quality. 192kbps is high quality. 320kbps is the best quality (indistinguishable from original for most listeners).
Will I lose audio quality?
MP3 is "lossy", so there is some theoretical loss. However, at 192kbps or higher, it is very hard to hear the difference.
Is the conversion private?
Yes. We process the audio directly in your browser using WebAssembly technology.
