JPG or PNG. It fills the video frame, with black bars if the shape differs.

Honest note: where the browser supports it, this tool builds a true MP4 right on your device. On browsers that cannot, it records the video in real time while the audio plays, and if MP4 recording is not available there either, it downloads a WebM instead and tells you so. It never renames another format to .mp4.

Your files never leave your device. This tool runs entirely in your web browser. Nothing is uploaded, nothing is stored, and there is no account to create. Close the tab and the file is gone from here too.

How it works

  1. Add your file using the box above, or drag and drop it in.
  2. Choose your options, if the tool has any.
  3. Press the button, and your finished file downloads right away.

The whole job happens on your own device, usually in a few seconds. There are no queues and no watermark added to your file.
