GIF collage maker
Free GIF collage maker: put two GIFs side by side or stack them vertically—auto-sync loops, animated GIF collage creator, preview and download in your.
What is a GIF collage maker?
A GIF collage maker combines two animated GIFs into one file that plays both at the same time—side by side or stacked vertically. It is not the same as /gif-combiner, which plays clips back to back. Upload GIF A and GIF B, pick a layout, and the tool syncs frame counts by looping the shorter animation. Preview and download client-side.

Tips for GIF collages
Get cleaner side-by-side or stacked GIFs.
- 01
Match heights for horizontal
Similar-sized GIFs align better side by side—resize first if needed.
- 02
Match widths for vertical
Stacked GIFs center when widths differ; similar widths look neater.
- 03
Shorter loops repeat
A 10-frame GIF beside a 30-frame GIF loops three times automatically.
- 04
Trim first
Use /shorten-gif to cut intros before collaging.
- 05
Sequential join elsewhere
For A-then-B playback, use /gif-combiner instead.
- 06
Still image merges
For PNG side-by-side stills, use /merge-images.

Technical details
How client-side GIF collage works.
- Dual decode
- gifuct-js decompresses both GIFs with full frame patches.
- Compositing
- Each output frame blends A and B on a shared transparent canvas.
- Frame sync
- Output frame count equals the longer GIF; shorter GIF index wraps with modulo.
- Delay
- Per output frame uses the max delay of the two source frames at that step.
- GIF encode
- gifenc writes the combined animation with loop metadata.
- Limits
- 15 MB per GIF; memory scales with frame count and canvas size.

Authoritative references on collage art, animated GIF technology, the Canvas rendering technology this tool uses, and the PNG output format.
“Collage is a technique of art creation, primarily used in the visual arts, but in which artwork is made from an assemblage of different forms, thus creating a new whole.”
Collage as an art technique: A GIF collage extends the traditional collage concept into animation — combining two separate GIFs side-by-side or stacked into a single composited animation, creating a new whole from separate parts. en.wikipedia.org/wiki/Collage
“The Canvas API provides a means for drawing graphics via JavaScript and the HTML canvas element.”
Canvas API (client-side compositing): This tool uses Canvas 2D to composite decoded GIF frames onto a shared canvas — rendering both animations side-by-side or stacked, all locally in your browser. developer.mozilla.org/en-US/docs/Web/API/Canvas_API
“PNG supports lossless data compression, making it useful for storing graphics that need to be edited repeatedly without losing quality.”
PNG image format: While this tool outputs GIF, the PNG format specification documents how lossless compression works — relevant for understanding image format fundamentals used in the tool's decoding pipeline. w3.org/TR/PNG/
“The Graphics Interchange Format is a bitmap image format that supports up to 8 bits per pixel, allowing a single image to reference a palette of up to 256 distinct colors.”
GIF format and animation: This tool decodes and re-encodes GIF files using gifuct-js and gifenc, preserving the GIF format's palette-based color and frame animation capabilities throughout the collage process. en.wikipedia.org/wiki/GIF
