MP3 to WAV FAQ

How do I convert MP3 to WAV?

Drop your MP3 file onto the upload area (or click Choose file), then click Convert. Download the WAV when it's ready.

Does converting MP3 to WAV improve the sound quality?

No. MP3 is lossy, so detail removed during MP3 encoding cannot be recovered. WAV gives you an uncompressed, lossless copy of the current audio — useful for editing, not for restoring lost quality.

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

WAV stores audio uncompressed, so a file is typically about 10 times larger than the equivalent MP3. That's expected — the size buys you an edit-ready, lossless format.

When should I convert MP3 to WAV?

Convert when a program requires WAV input, when you're editing audio and want to avoid stacking MP3 compression, or when preparing tracks for CD burning.

Is my audio uploaded anywhere?

No. The conversion runs entirely in your browser and your files never leave your device. Nothing is stored or logged.
