How to convert WAV to MP3
Converting WAV to MP3 takes three quick steps:

What is WAV?
WAV stores uncompressed, CD-quality audio with no loss of fidelity. The files are large, but the perfect quality makes WAV the standard for recording, editing and mastering before exporting to a smaller format.
What is MP3?
MP3 is the most popular audio format in the world. It uses lossy compression to shrink music and recordings to a fraction of their original size while keeping good sound quality, and it plays on virtually every device ever made.

Why convert WAV to MP3?
Converting WAV to MP3 gives you a file that is better suited to music and podcasts and sharing audio anywhere, and that opens it up to far more apps, devices and websites.
What MP3 gives you: plays on every device, small file sizes and adjustable bitrate.
Where WAV falls short: very large files, impractical for streaming and sharing and no built-in metadata standard. Converting keeps your content while moving to a format that matches where the file is going.
Tips for the best results

- You can convert several files in one go — add as many WAV files as you like and download them together.
- Everything runs locally in your browser, so even large files convert quickly and nothing is uploaded.
