Free tool
Video collage maker, clips side by side.
Put two, three or four videos in one frame: side by side, one above the other, one big with two small, or a grid of four. Pick a 16:9 frame for YouTube, 9:16 for Reels and TikTok, or a square, set the gap, the rounded corners and the background colour, choose where each clip starts and whose sound you hear, and save one MP4. It all happens in your browser, so the clips are never uploaded.
Each clip fills its box and is cropped to fit. Move clips up to change their place.
The videos are put together in your browser. They are never uploaded.
How it works
Clips in, one video out.
02 / Timing
Line the clips up
Set where each clip starts so they play in step, and pick whose sound you hear.
03 / Save
One MP4, full HD
Every frame is drawn at the frame size you pick and saved as an H.264 MP4 that plays everywhere.
Questions
Good to know.
How do I put two videos side by side?
Drop both videos, keep Two side by side, press Play to check, then Save the collage.
Can I make a vertical collage for Reels or TikTok?
Yes. Pick the 9:16 frame and a stacked layout.
Whose sound is in the video?
The clip you pick under Sound from, or none.
What if the clips are different lengths?
By default the collage stops with the shortest clip. You can run it to the longest instead; the others hold their last frame.
Are my videos uploaded?
No. Everything happens in your browser tab.
