This one runs on your credits. The same samples, every one of them, in half the bytes.

How to convert WAV to FLAC
- Drop the audio.
- Nothing to choose.
- Press Convert and download.
What happens to your file
The PCM samples are packed with FLAC: nothing is thrown away, the file is typically 50–60% of the WAV, and any player decodes it back to the identical samples.
An MP3 or M4A is not accepted here on purpose: wrapping a lossy file in FLAC makes it larger and no better.
Questions
Is FLAC really lossless?
Yes — decode it and you get the WAV back, bit for bit. It is the format archives and audiophiles keep.
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.
