About WAV to MP3
Convert WAV audio files to MP3 format with configurable bitrate, entirely in your browser. MP3 compression can reduce file sizes by 90% or more while maintaining good audio quality. Choose from bitrate options including 128 kbps for speech and podcasts, 192 kbps for general music, or 320 kbps for high-fidelity audio. The conversion uses FFmpeg running locally in your browser –no file uploads, no server processing, complete privacy. Ideal for preparing audio for web distribution, email attachments, or reducing storage usage while keeping your files sounding great.
Frequently Asked Questions
What bitrate should I choose?
128 kbps is fine for speech and podcasts. 192 kbps works well for most music. 320 kbps is near-lossless quality for critical listening.
How much smaller will the MP3 be?
Typically 90-95% smaller. A 50 MB WAV file becomes roughly 3-5 MB as MP3 at 128 kbps.
Is the audio quality affected?
MP3 uses lossy compression, so some audio data is discarded. At 192 kbps and above, the difference is inaudible to most listeners.
