WAV files are 16-bit PCM and much larger than MP3, often around 10 times the size. Converting does not restore quality that the MP3 already lost.

Frequently asked questions
Quick answers about the ConvertKit Lite MP3 to WAV tool.
Are my audio files uploaded to a server?
No. The conversion runs in your browser, so your files stay on your device.
Will the sound quality improve?
No. MP3 is lossy, so detail removed during MP3 encoding cannot be brought back. WAV simply stores the decoded sound without further loss, which is useful for editing software and devices that need WAV.
Why is the WAV file so much bigger?
WAV stores raw, uncompressed audio. A 3 MB MP3 can become a WAV of 30 MB or more.
Which sample rate should I choose?
Keep Original unless you need a specific rate. Lower rates such as 16,000 Hz make smaller files and suit speech, but they cut high frequencies.
Can I convert many files at once?
Yes. Add several MP3 files, convert them together, and download each WAV or one ZIP. Very long files use a lot of memory, so convert those a few at a time.
Are tags and cover art kept?
No. The WAV contains the audio only, without ID3 tags or album art.
