How to convert WAV to MP3
- Sign in — 500 free credits a month.
- Drop the WAV in the workbench.
- Run Convert and download the MP3.
What happens to your file
PCM samples are encoded to MP3 at a bitrate chosen from the source’s sample rate and channels — 192 kbps for stereo music, less for mono voice — which is transparent to nearly all listeners.
Questions
What does it cost?
One credit per megabyte of input. A 50 MB WAV is 50 credits.
Do it once, not on every form
Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
