How do I convert WAV to MP3?
WAV files store uncompressed audio and get very large, which makes them awkward to email, upload, or store in bulk. Converting to MP3 shrinks them dramatically while staying easy to play anywhere.
Your MP3 is ready
Download MP3
Upload your WAV file and select MP3 as the output, then download the result. WAV is lossless and uncompressed, so the MP3 will be far smaller (often around a tenth of the size) with a slight, usually inaudible quality reduction at a good bitrate.
How it works
1
Upload your WAV file
Select or drag in the WAV recording you want to compress.
2
Choose MP3 as the output
Set MP3 as the target so the converter compresses the uncompressed audio.
3
Download your MP3
Save the smaller MP3 file, ready to share or sync to any device.
Frequently asked questions
A lot. WAV is uncompressed, so an MP3 is often roughly a tenth of the original size depending on bitrate, which makes storage and sharing much easier.
MP3 is lossy, so some data is discarded, but at a higher bitrate the loss is minimal and most listeners cannot tell during normal playback.
Yes, if you plan to edit, master, or archive the audio. WAV is the better source for editing, while MP3 is best for the final shareable copy.
Yes. MP3 is supported by essentially every phone, computer, browser, and media player, unlike large WAV files that some apps reject.
No. The conversion happens in your browser with no downloads, installs, or signup.
