Why convert WAV to MP3?
WAV is uncompressed audio and the standard in recording and editing software. Nothing is lost, but a minute of stereo sound takes about 10 MB.
MP3 is the most compatible audio format: every phone, car stereo, speaker and app plays it. Its lossy compression makes files about a tenth of the size of a WAV.
Choose MP3 when you want sound that plays everywhere in a small file.

Questions about converting WAV to MP3
Is the WAV to MP3 converter free?
Yes. It is free, with no sign-up, no watermark and no limit on how many files you convert.
Is my file uploaded?
No. Your browser reads and converts the file on your own device; nothing is sent to 4Dev or anyone else.
Is there a size limit?
Files can be up to 500 MB. The result is built in your device's memory, so very large files are better converted on a computer than on a phone.
Will converting to MP3 reduce quality?
MP3 is lossy, so it drops detail that is mostly inaudible or invisible. The default settings are a good balance; choose a higher quality or bitrate for archiving.
Which browsers can do this?
Current Chrome, Edge, Safari and Firefox on a computer, and Chrome or Safari on a phone. The format list only offers what your browser can actually create.
