WAV to MP3 Converter
- Step 1: Pick your WAV file (or up to 20 at once) and drop it into the upload area. Large files are welcome.
- Step 2: Conversion starts automatically. If needed, pick a bitrate; Auto works well for most audio.
- Step 3: When the progress bar reaches 100%, click Download to save your MP3. For batches, download each MP3 as it appears.
You can upload up to 20 files at once.
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.
