FREE TOOL · ON YOUR DEVICE
Merge videos online free
Join several clips into one video, in the order you want. If you mix vertical and horizontal videos, each one is shown whole inside the same canvas, on a blurred background or with black bars. Each clip keeps its sound.
- Free, no watermark
- Your videos never leave your device
- Vertical and horizontal together
- Add your videos
- Choose the canvas
- Merge and download
HOW TO USE IT
Three steps.
Add your videos
Drop or choose 2 to 10 MP4, WebM or MOV videos and reorder them by dragging the handle or with the arrows.
Choose the canvas
Like the first video, 16:9 for YouTube, 9:16 for Reels and TikTok or 1:1, and the background for clips that do not fill it.
Merge and download
Press “Join videos” and download the result as MP4 (or WebM if your browser cannot create MP4).

Merge videos: common questions
Can I merge videos of different sizes?
Yes. Each clip is fitted whole into the canvas you choose; if it does not fill it, the gap is filled with the same video blurred or with black. Nothing is stretched or distorted.
Is the sound kept?
Yes. Each clip’s sound stays with its picture; if a clip has no sound, that part is silent.
How long does it take?
Everything is re-encoded on your device, so it takes about as long as the result lasts. On a phone it may take a little longer.
What are the limits?
2 to 10 videos, up to 300 MB each and 10 minutes in total, with output up to 1080p. Saving video needs WebCodecs, found in recent versions of Chrome, Edge, Firefox and Safari.
Are my videos uploaded to a server?
No. The tool runs inside your browser: videos are read and processed on your device and are not sent to Cocuyo or to any third party. The libraries are served from our own site, with no external services. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
