How it works

Three steps. No signup. Nothing leaves your browser.

  1. 1

    Add your clips

    Drop two or more videos. MP4, MOV, WebM, or MKV all work together.

  2. 2

    Check the order

    Clips merge top to bottom. Remove one or add more until it reads right.

  3. 3

    Download the MP4

    Get one continuous video, sized to your first clip, ready to post.

Frequently asked questions

Is this video merger really free?
Yes. No signup, no watermarks, no upload caps. Use it as much as you want.
Do my videos get uploaded anywhere?
No. The clips are decoded and stitched entirely in your browser. Nothing leaves your computer.
Can I mix different formats and sizes?
Yes. The output uses the first clip's dimensions, and other clips are fitted inside that frame. Mixing portrait and landscape works, the smaller side gets black bars.
What happens to the audio?
Sound is kept when every clip has an audio track with the same sample rate and channel count, which is normal for clips from the same phone. If they differ, the merged video comes out silent and you get a note.
How long can the videos be?
There is no hard cap, but merging re-encodes every frame, so very long videos take a while. Keep the tab open until it finishes.
