What bitrate is the MP3 encoded at?

Files are encoded at a standard 128kbps, a widely-compatible bitrate that works well for speech and most music.

Does this work with mono and stereo files?

Yes, both are supported automatically — the output MP3 keeps the same channel count as your WAV file. Files with more than 2 channels aren't supported.

Will there be any quality loss?

MP3 is a lossy format, so some quality is lost compared to the original uncompressed WAV — but at 128kbps this isn't noticeable for typical listening.

Is my WAV file uploaded anywhere permanent?

Your WAV file is encoded entirely in server memory and the result is deleted immediately after download — nothing is kept.

Features

Pure-JavaScript MP3 encoding
Encoded with lamejs, a JavaScript MP3 encoder, instead of a full ffmpeg process — simpler and just as fast for this one format pair.
Mono and stereo preserved
Both mono and stereo WAV files convert correctly, keeping the same channel count. Files with more than 2 channels (surround) aren't supported.
Standard 128kbps output
Encoded at a widely-compatible 128kbps bitrate, a solid balance of file size and quality for speech and most music.
Rejects invalid WAV files upfront
Malformed or non-WAV files are rejected with a clear error before any encoding is attempted.

Supported formats

.wav

WAV (PCM)

Standard uncompressed PCM audio, 8/16/24/32-bit and floating-point all supported.
