Files never leave your device
Join MP4, MOV, MKV or WebM clips into one video: put them in order by dragging, and clips of different sizes are fitted to the frame of the first one. Add a smooth crossfade between clips if you like. All in your browser — the files are not uploaded.
How it works
- Add two or more videos and drag them into the order you need.
- Choose a transition: a straight cut or a crossfade of 0.5–2 seconds.
- Click Merge and download one video in the format of the first file.
Frequently asked questions
What if the videos have different sizes?
The frame size and frame rate of the first video are used. Other clips are fitted into it without stretching, with black bars where the proportions differ.
What happens to clips without sound?
Silence of the same length is added, so the sound of the other clips stays in sync with the picture.
Is it free?
Yes. All tools are free, with no sign-up and no watermarks.
Are my files uploaded to a server?
No. Everything runs in your browser, so your files never leave your device.
