About Video Joiner

Video Joiner merges multiple video files (MP4, WebM, MOV, AVI, and more) into one continuous video directly in your browser. It uses HTML5 Canvas API and MediaRecorder API to handle file selection, clip order, merging, and download on the client side.

It is useful for combining presentation clips, stitching together footage from multiple cameras, or merging short clips for social media. The workflow is simple: drag and drop videos, use arrow buttons to reorder the playback sequence, then click merge.

Videos with different resolutions are normalized to the largest dimensions, reducing the need for pre-conversion work. Choose WebM when you want a lighter browser-friendly output, choose MP4 when compatibility matters, and adjust bitrate to balance quality and file size.

If you need to cut unwanted parts before merging, use [Video Trimmer](/en/movie/video-trimmer/). To change the merged file format, use [Video Converter](/en/movie/video-converter/). To align dimensions, use [Video Resizer](/en/movie/video-resize/). To adjust FPS, use [Video Frame Rate Converter](/en/movie/video-frame-rate-converter/).
