How to convert MP3 to WAV

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.
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.

Why convert MP3 to WAV?
Converting MP3 to WAV gives you a file that is better suited to audio recording and editing and mastering and production, and that opens it up to far more apps, devices and websites.
What WAV gives you: perfect, lossless quality, universally supported by editors and no compression artefacts.
Where MP3 falls short: lossy — some quality is discarded, not ideal for editing or mastering and no lossless option. Converting keeps your content while moving to a format that matches where the file is going.

- You can convert several files in one go — add as many MP3 files as you like and download them together.
- Everything runs locally in your browser, so even large files convert quickly and nothing is uploaded.
