WAV to MP3 Converter

Convert WAV files to MP3. Free, without uploading.

This tool converts WAV files to MP3. WAV is uncompressed audio: no quality loss, but large files. Editing and recording software use it a lot.

MP3 is the most common audio format. It uses lossy compression and plays on almost every device. MP3 is lossy; you choose the quality from 96 to 320 kbps. 192–256 kbps is enough for music, 128 kbps for speech.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the WAV file, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the MP3 file.

Frequently asked questions

Will audio quality drop when converting to MP3?

MP3 is lossy, so there is a small loss you won’t hear at higher bitrates. If the source is already lossy, a higher bitrate won’t improve it.

Is there a file size limit?

No fixed limit; your device’s memory decides. Computers usually handle files up to 1–2 GB.

Is my file uploaded?

No. Your WAV file is converted to MP3 inside your browser.
