Merge Videos

Join videos one after another into one MP4, in your browser

Drop videos here

Or choose them: MP4, MOV, WebM, MKV and M4V; they're merged in your browser and never uploaded

The merged video is written as you watch the progress, in about the time it plays, and held in memory until it's downloaded, so very long ones may not fit. AVI, FLV and WMV aren't read.


How to merge videos

  1. Drop your videos on the page or choose them, up to 20.
  2. Put them in order by dragging them or with their arrows.
  3. Pick the size, the first video's or another, and whether to keep the sound; merge and download.

Questions

Can I merge videos of different sizes or shapes?

Yes: each is fitted whole into one size, with black bars where its shape differs, so nothing is cut off.

Are my videos uploaded?

No. They're merged by your browser, on your device, and never sent anywhere.

What if one video has no sound?

It's silent in the merged video, and the sound of the others stays in step with their pictures.

How long does it take?

Every video is written again, in about the time they play together, often less on a recent device.
