Merge Videos Online - Fast & Easy

Need to combine multiple video clips into one seamless file? Whether you are merging presentation segments, combining footage from different sources, or creating a longer video from shorter clips, complex video editing software often feels like overkill.

Our video merger lets you upload multiple files, arrange them in any order, set custom durations, and download a single merged video. No complicated timelines, no steep learning curves. Your videos are processed entirely in your browser, keeping your content private and secure.

Drag, drop, arrange, and merge. It is that simple. Because combining videos should not require a degree in video editing.

Frequently Asked Questions

How many videos can I merge at once?

There is no hard limit on the number of videos you can merge. The only constraint is your device's available memory and processing power.

By default, all videos are resized to match the dimensions of the first video you upload. You can also set custom global dimensions if needed.
