Combine GIFs into one

The GIF Combiner merges up to 20 GIFs (or still images) into a single animated GIF in one of three layouts: one after another, side by side, or stacked vertically. Sequence mode plays each GIF in turn at the first GIF’s size; side-by-side and stacked modes play them simultaneously, looping shorter GIFs until the longest one finishes.

How to use GIF Combiner

  1. 01

    Add GIFs

    Drop two or more GIFs (images work too). Reorder or remove them as needed.

  2. 02

    Pick a layout

    One after another, side by side, or stacked — plus a background colour for letterboxing.

  3. 03

    Combine

    Click Combine GIFs and download the merged animation.

Sequence vs side-by-side

Use one after another to build a compilation or a multi-step tutorial: each GIF plays in full before the next begins, so the result is as long as all inputs added together. Use side by side or stacked for comparisons — before/after edits, two takes of the same move, or a product shown from two angles — where viewers should see both at once.

In side-by-side mode, the combined GIF lasts as long as the longest input, and shorter GIFs loop to fill the time. If one GIF is much longer, trim it first, or change its speed so both finish together for a perfect loop.

Keeping the merged GIF manageable

Merging adds frames and pixels, so combined GIFs grow quickly. Resize inputs to similar dimensions beforehand with Resize GIF, and run the result through the GIF compressor if it needs to fit an upload limit. To add a title card between clips, make it as an image — or with Add Text to GIF — and drop it into the list.

GIF Combiner FAQ

How do I combine two GIFs into one?

Drop both GIFs into the GIF Combiner, choose “One after another” or “Side by side”, and click Combine GIFs. The merged GIF downloads as a single file.

Can I put two GIFs side by side?

Yes. Choose “Side by side” to place them horizontally or “Stacked” to place one above the other. Both play at the same time.

What happens if the GIFs are different sizes?

Everything is scaled to match the first GIF — its size in sequence mode, its height side by side, or its width when stacked — with a background colour filling any gaps.

Are my files uploaded to a server?

No. GifRush processes everything locally in your browser using JavaScript, Canvas, Web Workers and WebCodecs. Your files never leave your device, and closing the tab discards them.
