When to Use WAV vs MP3
Use WAV when:
- ✓Importing audio into a DAW for editing
- ✓Using audio software that requires uncompressed input
- ✓Avoiding re-encoding quality loss across multiple exports
- ✓Submitting to platforms that require WAV (radio, broadcast)
Stick with MP3 when:
- •Streaming or sharing audio online
- •Storage space is a concern
- •Final delivery to listeners (not editors)
- •Uploading to music platforms or social media
100% Private
No uploads. The Web Audio API decodes your MP3 locally and writes raw PCM data to a WAV container in your browser.
Instant
No server roundtrip means conversion is limited only by your CPU — typically seconds for a standard song.

Frequently Asked Questions
Does converting MP3 to WAV improve the quality?
No. When you compress audio to MP3, the discarded data is gone permanently. Converting back to WAV gives you an uncompressed file at the same quality as the MP3 — it won't restore the original lossless quality. What you gain is compatibility: WAV files work in every audio editor without any decoding overhead.
Why would I want a WAV file if MP3 quality is the same?
Professional DAWs like Pro Tools, Logic Pro, and Ableton prefer WAV for editing because it requires no real-time decoding. WAV files also don't accumulate generation loss — if you edit and re-export an MP3 repeatedly, quality degrades each time. WAV lets you edit without that risk.
Are my MP3 files uploaded to a server?
No. The entire conversion happens in your browser using the Web Audio API. Your MP3 is decoded locally, written out as a WAV file, and downloaded directly to your device. Nothing is transmitted.
How big will the WAV file be?
WAV is uncompressed, so a 3-minute stereo MP3 at 128kbps (~3MB) will become roughly 30MB as a 44.1kHz 16-bit WAV. This is expected — you're trading file size for maximum compatibility.
What sample rate does the WAV use?
The output WAV uses the same sample rate as the decoded MP3 (typically 44,100 Hz). The bit depth is 16-bit PCM, which is standard CD quality and compatible with all audio software.
