Video Clip Merger
Video Clip Merger is a free online video joining tool. Add MP4, MOV, M4V, WebM, or OGV clips, drag them into order, and merge them into one MP4 or WebM file.
The first clip sets the output frame size. Other clips are scaled proportionally and padded, with video and audio normalized when needed; fully compatible clips are joined directly using a fast path. FFmpeg.wasm performs everything locally in your browser, and the finished file downloads immediately.
How to Use
- Add 2 to 10 video clips, each no larger than 150 MB and no more than 300 MB in total
- Drag clip cards into playback order, and preview or remove clips as needed
- Choose MP4 or WebM and a video quality; the first clip determines the output frame size
- Start merging and download the finished video as soon as it is ready
FAQ
Are my videos uploaded to a server?
No. Reading, normalization, merging, and download all happen in your current browser.
Can I merge videos with different resolutions or aspect ratios?
Yes. The first clip sets the output frame. Other clips are scaled proportionally and padded to fit without being stretched.
Can I include a video with no audio track?
Yes. The tool adds a silent audio track internally so silent clips remain compatible and merge in the correct order.
Should I choose MP4 or WebM?
MP4 works with more devices and players. WebM is well suited to the web and often keeps good quality at a smaller file size.
