How to convert videos to MP4

  1. Add your videos.
  2. Choose MP4 or WebM.
  3. Click Convert and download.
Is my video safe?

Yes. Your video is only used to create your result — it’s never shared and never used to train AI.

Which browsers work?

Recent Chrome, Edge and Safari 17+ work best. Firefox supports most tools; if a codec isn't available we'll tell you.

Should I choose MP4 or WebM?

MP4 plays on virtually every phone, computer, TV and editor — choose it unless you specifically need WebM for a website or web app.

Is the video re-encoded?

Only when it has to be. If the video and sound inside can go straight into the new format they're copied as they are, which is fast and lossless.

Why does it say my browser can't decode the video?

iPhones often record HEVC (H.265), which some browsers can't decode. Safari, or Chrome/Edge on a computer with HEVC support, usually can.
