Combine multiple video clips into one, in whatever order you pick. Clips with different resolutions are automatically scaled and letterboxed to match the first clip, so you don't need to match them beforehand. Reorder with the up/down buttons rather than dragging. Everything runs inside your browser, so the videos are never uploaded to a server.
How to use it

- 2Use the up/down buttons in the list to set the order to stitch them in.
- 3Click Merge and download the result.
When it comes in handy
For example, it's handy when you've recorded several separate clips that need to become one continuous video.
Clips shot on different devices with different resolutions are automatically letterboxed to match the first clip, so there's no need to resize them beforehand.
What happens with mismatched resolutions
Stitching requires every segment to share the same frame size, so the other clips are scaled (keeping their aspect ratio) to match whichever clip you place first, with any leftover space filled by black bars (letterboxing). Reordering changes which clip sets that base resolution — put your highest-resolution clip first if you want to preserve the most quality.
Frequently asked questions
Are the videos uploaded to a server?+
No. Merging runs inside your browser, so the videos never leave your device.
How do I change the clip order?+
Use the up/down arrow buttons next to each item in the list.
Can I merge a clip that has no audio track?+
Right now every clip needs an audio track. Mixing in a clip without one will show an error.
What's the minimum number of clips?+
You need at least 2.
