Video Collage Maker: Side by Side & Split Screen Free

How to put videos side by side

Combine 2 to 6 videos into one: side by side, stacked, grid, mosaic, big-plus-side, picture-in-picture or a diagonal split. Choose 16:9, 9:16, 1:1 or 4:5, round the corners, add gaps, borders, labels and a solid or blurred background, decide how long the collage runs and which sound to use (or mix them all), then export an MP4.

Drop two or more videos at once (or add them one by one), choose Side by side, Stacked or Grid, and the preview plays them in sync. Reorder clips with the arrows, set each one to fill its cell or fit the whole picture, then click Create collage video. The collage is rendered frame by frame into a single MP4.

Detailed guide

Choose the right layout

Different comparisons need different layouts; the list adapts to the number of clips.

Layout	Clips	Great for
Side by side	2 to 6	Before/after, comparisons, duets
Stacked	2 to 6	Vertical 9:16 reactions and tutorials
Grid	2 to 6	Montages, multi-camera views
Big + side / bottom	2 to 6	Main video with secondary angles
Picture-in-picture	2 to 6	Reactions, gameplay with facecam
Mosaic	3 to 5	Dynamic social collages
Split diagonal	2 to 6	Stylish versus and transformation videos

Before and after videos

Turn on Show labels on clips and name each cell (for example Before and After, Day 1 and Day 30, or Original and Edited). Labels appear as tidy badges in the corner of each clip, which makes transformation, renovation, fitness, color-grading and editing comparisons instantly clear.

Timing and sound

Clips rarely have the same length. Choose whether the collage lasts as long as the longest clip, the shortest, or a specific clip; shorter clips either loop or freeze on their last frame. For audio, use one clip's sound, mix all of them (with a volume slider per clip), or export silently and add music later.

Finish your collage

Add captions or a watermark to the finished collage, or resize it for another platform.

Frequently asked questions

How do I put two videos side by side?

Add both videos, choose the Side by side layout and click Create collage video. Use Stacked for one above the other.

How many videos can I combine?

Up to six videos in one collage.

Can I make a picture-in-picture video?

Yes. Choose Picture-in-picture: the first clip fills the frame and the others appear as small windows in the corner. Reorder clips to choose which is the main one.

What happens if the videos have different lengths?

Choose whether the collage follows the longest, shortest or a specific clip. Shorter clips loop or freeze on their last frame.

Which audio is used?

Your choice: the sound of one clip, a mix of all clips with individual volume, or no sound.

Can I label the clips for a before and after video?

Yes. Turn on Show labels on clips and type a label for each one.

Is anything uploaded?

No. All videos are processed in your browser.
