Merge Videos

Upload your clips in the order you want, and they are joined into a single MP4 video. Videos with different formats, sizes, orientations and frame rates are matched automatically, with black bars where the shapes differ, and silent clips get silent audio so nothing goes out of sync.

How to merge videos

1. Choose two or more videos (MP4, MOV, MKV, AVI or WEBM).
2. Put them in the right order with the arrows.
3. Choose the video size and click Convert, then download the merged MP4.

Video merger features

• Join up to 20 clips in any order.
• Mix MP4, MOV, MKV, AVI and WEBM in one project.
• Portrait and landscape clips fit without stretching.
• Output as MP4 that plays everywhere, in the first clip’s size, 1080p or 720p.

Best results

For the cleanest result, merge clips with the same orientation, for example all vertical phone videos for a Reel. When you mix vertical and horizontal clips, choose the size of the clip that matters most as the first video.
