    Batch WAV to MP3

    Upload up to 20 WAV files at once and Converter App will deliver matching MP3s in seconds. Download each MP3 as it finishes, perfect for playlists, lectures, and podcasts.

    Bitrate and channel control

    Pick Auto or set a bitrate yourself: 320 kbps for pristine, 192 kbps for music, 128 kbps for talk, 96 kbps for notes. For speech, switch to mono to halve file size with little loss; keep your original WAV for editing since MP3 is lossy.

    Free to use

    Converter App is free. No sign-up, no watermarks, and no daily caps within fair use.

    Smaller MP3s, smart defaults

    Converter App shrinks WAV by up to 90% with an Auto setting that balances size and clarity for everyday listening. Always convert from the original WAV, as re-encoding an MP3 only adds artifacts.

    Fast in your browser

    Most conversions finish in seconds on our high-speed servers, and batch jobs stay quick. Converter App handles large WAV files with no daily caps and runs in any modern browser on desktop or mobile.

    Privacy first

    Your audio stays yours. Transfers are secured, and files are removed automatically shortly after conversion. We never require an account, and only you can access the download link.

    What Is the Difference Between WAV and MP3?

    WAV stores audio without compression and preserves every detail of the recording, which is great for editing but heavy on storage. MP3 compresses audio to remove information you would not notice, dramatically shrinking file size while keeping the listening experience clear for everyday use.

    Why Is It Smart to Convert WAV to MP3?

    Free up space without a big hit to quality. For music, 192 kbps is a solid default. For podcasts and voice, 96–128 kbps in mono keeps speech clear. For archiving or DJ sets, use 320 kbps. Or pick Auto and let us choose a sensible setting. Also try our MP3 Converter for other audio formats.

    How Does MP3 Audio Compression Work?

    MP3 analyzes tiny time slices of audio and allocates bits where your ear is most sensitive, discarding masked sounds you would not perceive. The result is often a 10:1 reduction in size with minimal audible change.

    Can I Convert WAV to MP3 Without Losing Quality?

    MP3 is lossy by design, so some detail is always removed. At higher bitrates with a modern encoder, most listeners will not hear a difference. If you need file-perfect preservation, choose a lossless format such as FLAC.
