How to convert MP4 to MP3 on Windows

  1. 1

    Select your MP4 files

    In File Explorer or on the desktop, select one MP4 file or as many as you like. The first time, Filee offers to download FFmpeg, the free engine it uses for this conversion.

  2. 2

    Hold Ctrl and drag

    Hold Ctrl (or the key you set in Filee) and drag the files. A donut of formats opens at the cursor. Prefer menus? Right-click and choose Convert with Filee.

  3. 3

    Drop on MP3

    Release the files over MP3. A progress ring counts up, and each MP3 file is saved next to its original.

What Filee does for MP4 → MP3

Save the soundtrack of a lecture, concert or interview as an MP3 that plays everywhere: in the car, on an old player or in a transcription tool.

  • Uses FFmpeg, a free optional engine that Filee downloads once into its own folder (about 100 MB). Programs installed on your PC are never used.
  • Only the sound is saved, without the video track.
  • The MP3 128k preset makes smaller files, ideal for speech.
  • Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
  • Private: files are converted on your PC and never uploaded, even without internet.
  • Saved next to the original, or in a folder and with a file name pattern you choose.

MP4 can also become

  • WEBM
  • MOV
  • MKV
  • AVI
  • GIF
  • M4A
