MP3 to MP4 converter with a cover image

Put your track and a cover picture together as a video you can post. Nothing is uploaded: the file opens in your browser and stays on your device.

Shape

Choose a track and a cover image to see the video's picture here.

How it works

  1. Choose your track (up to 10 minutes) and a cover image.
  2. Pick the shape: square, vertical or wide.
  3. Press Make the video, keep the page open while it records, then download it.

What you get

  • Square 1080×1080, vertical 1080×1920 or wide 1920×1080.
  • Your cover shown whole over a blurred copy of itself, for the whole track.
  • Tracks up to 10 minutes. No watermark.

FAQ

Questions

Is my file uploaded?
No. The file is opened by your browser and processed on your device. Nothing is sent to us, and it is released when you load another file or leave the page.
Do I always get an MP4?
Safari and recent Chrome and Edge save an MP4. Firefox and older Chrome save a WebM video instead; the page tells you which before you start.
Why does it take as long as the track?
Your browser plays the track once while it records the video. A three minute song takes about three minutes.
