Processing runs inside your browser with ffmpeg.wasm, so the video is never uploaded. Use a few short clips to keep it light.

  2. Reorder them with the arrows.
  3. Click Merge and download the seamless video.

FAQ

Can I merge different-sized clips? Yes. Each clip is fitted into a 720p frame with padding, without distortion.

Is the video uploaded to a server? No. Everything runs in your browser.

Do all clips need audio? Preferably, since it merges both picture and sound; a clip with no audio may cause an error.
