About MP3 and WAV

Understanding the difference between MP3 compressed audio and WAV uncompressed audio.

MP3

What is MP3?

MP3 (MPEG-1 Audio Layer III) is a compressed audio format that reduces file through lossy compression. While great for listening, MP3's compression makes it less suitable for audio editing and professional production workflows.

WAV

What is WAV?

WAV (Waveform Audio File Format) is an uncompressed audio format that stores raw audio data. WAV files are larger than MP3 but provide lossless audio quality, making them the standard format for audio editing, music production, and professional audio workflows.

Frequently Asked Questions

Everything you need to know about converting MP3 to WAV online.

How do I convert MP3 to WAV?

Drop your MP3 file into the converter above or click to select it. The conversion happens in your browser and you can download the WAV file when ready.

Will the WAV be higher quality than the MP3?

The WAV will not recover quality lost during MP3 compression, but it will not lose any further quality. The WAV output is a lossless copy of the MP3 audio.

Is my file uploaded to a server?

No. All conversion happens locally in your browser using FFmpeg WebAssembly. Your files never leave your device.

Why is the WAV file so much larger than the MP3?

WAV stores uncompressed audio data, which is typically 5-10x larger than the equivalent MP3 file. This is the tradeoff for lossless, editable audio.

Is there a file size limit?

Files up to 200MB are supported. Since conversion happens in your browser, very large files may require more memory.
