Get the best conversion results
Follow these expert tips to maximize quality and efficiency when converting WAV to MP3.
Choose the Right Bitrate
For speech and podcasts, 128kbps is sufficient. For music, use 192kbps or 256kbps. For archival quality, use 320kbps. Higher bitrate means larger files but better quality.
Keep WAV Masters
Always keep your original WAV files as master copies. Use MP3 copies for sharing, streaming, and web delivery. You can always re-encode from the WAV master.
Check for Clipping
After conversion, listen to the MP3 to check for any clipping or distortion. If you hear artifacts, try a higher bitrate setting and re-convert.
Batch Convert for Efficiency
If you have many WAV files, convert them one after another. Since processing is local with no upload time, each conversion is fast and efficient.

How much smaller will my MP3 file be?

No. The entire conversion happens in your browser using the WebAudio API. Your WAV files are never uploaded, stored, or transmitted to any server. They remain on your device at all times.

What bitrate should I choose?
For speech and podcasts, 128kbps provides excellent quality with small file sizes. For music, 192kbps is the sweet spot. For archival or audiophile use, 320kbps provides the best MP3 quality possible.
