How to convert Video to M4A

Sign in — 500 free credits a month.
Drop the video in the workbench.
Run it and download the M4A.

What happens to your file

The audio stream is decoded and encoded to AAC at 160 kbps in an M4A container — the same format Apple Music and phone recorders use, a tenth the size of a WAV. Video frames are discarded.

Media processing costs real compute per minute, so it runs against your own credits, the first 500 each month free.

Questions

M4A or MP3?

Both play everywhere. M4A sounds a little better at the same size; MP3 is the older habit.

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.

Filmed from the extension: three upload fields on a job application, filled from one tap.

    "file_id": "<file id>",
    "operation": "video.extract-audio",
    "options": {
      "format": "aac"
