Why convert WAV to MP3?
WAV files are uncompressed, which means they offer the absolute highest audio quality possible. The problem is that they are massive. A simple three minute song in WAV format can take up 40 megabytes of space.
If you want to email a song to a friend, upload it to a website, or save space on your phone, you need to compress it. Converting a WAV into an MP3 shrinks the file size down to a tenth of its original size while keeping the audio quality surprisingly high.
How to compress your files
Upload your massive WAV file using the button above. The encoder will instantly start compressing the audio data. You can choose the bitrate depending on how small you need the file to be, but 320kbps is the standard for high-quality MP3s.
The entire conversion happens locally in your web browser. This means you do not have to wait for a 40 megabyte file to upload to a server, the process is practically instant.
Frequently Asked Questions
Will the MP3 sound worse than the WAV?
Technically, yes, because data is permanently removed. However, if you encode it at 320kbps, the vast majority of people will never be able to hear the difference, especially on standard headphones or car speakers.
Why is WAV the industry standard?
WAV is an entirely uncompressed, lossless format. This means it represents the exact, perfect digital recreation of the original sound wave without throwing a single byte of data away.
Should I convert my MP3 back to a WAV?
No. You cannot add quality back once it is gone. Converting an MP3 back into a WAV will just give you a massive file that still has the exact same low quality as the MP3.
