About Video Merger

Video Merger plays your videos back-to-back onto a canvas and records the result as one file, entirely in your browser. Note: the output is always WebM and has no audio, since canvas recordings don't carry sound; videos merge in the order you added them, and all clips are drawn at the first video's dimensions — later videos with a different aspect ratio will be stretched to fit.

How to use Video Merger

1Click the upload area and add two or more video files — they'll merge in the order you add them.
2Review the list and remove any you don't want.
3Click "Merge Videos" — each video plays through in sequence while the combined result is recorded.
4Preview and download the merged WebM file.

Frequently Asked Questions

Can I reorder videos before merging?

Not currently — they merge in the order they were added; remove and re-add files if you need a different order.

Does the merged video have audio?

No — since merging works by drawing frames to a canvas, and canvas recordings never carry audio, the output is silent.

What if my videos have different resolutions?

All videos are drawn at the first video's dimensions, so later clips with a different aspect ratio will appear stretched rather than letterboxed.

Is my file uploaded anywhere?

No, merging happens entirely in your browser.

Tips & Tricks

✓Merge videos with matching resolution and aspect ratio for the cleanest-looking result.
✓Merging takes roughly as long as the combined duration of all your clips, since each one plays through in full.
✓Since output has no audio, add a soundtrack afterward with a dedicated video editor if you need sound.
✓Keep the browser tab active and visible while merging, since the videos need to actually play for the canvas to capture them.
