Merge Videos

Media & Video Studio

Stitch multiple clips into one continuous video, in order.

What is Merge Videos?

Merge Videos joins two or more clips end to end into a single file, entirely in your browser. Add your clips, drag them into the order you want, and download one continuous video. It uses fast, lossless stream copy — nothing is re-encoded and nothing is uploaded, because the work happens locally with in-browser FFmpeg (WebAssembly).

How to use Merge Videos

  1. Add your clips

    Drop two or more videos on the drop zone or click to browse. MP4, WebM, MOV, MKV, and M4V are accepted. The in-browser engine starts loading in the background as soon as you add files.

  2. Set the order

    Drag clips by their grip handles, or use the up and down arrows, to arrange them top to bottom. That top-to-bottom order is the order they'll play in the merged file. Use the X to remove any clip.

  3. Merge

    Click Merge to concatenate every clip into one video. Because it copies the streams without re-encoding, merging is fast — but every clip must share the same codec, resolution, and frame rate.

  4. Preview and download

    Watch the merged result in the built-in player, then click Download to save the combined MP4. All of it stays on your device.
