What does GIF Merge do?

It combines multiple GIF files by appending their frames sequentially, creating one longer animation.

How many GIFs can I merge at once?

There is no hard limit, but merging many large GIFs may require significant browser memory. We recommend merging up to 10 GIFs at a time.

Do merged GIFs need to be the same size?

No, but mismatched sizes will result in inconsistent framing. For best results, resize all GIFs to the same dimensions first.

Can I reorder GIFs before merging?

Yes. Drag and drop GIF thumbnails to set the order before combining.

What happens to frame delays when merging?

Each GIF's frame delays are preserved. If GIFs have different speeds, the combined animation will reflect those differences segment by segment.

Will the merged GIF loop infinitely?

Yes, by default. You can change the loop setting after merging using the GIF Loop tool.

Does merging increase file size?

Yes. The merged file contains all frames from all source GIFs, so its size is approximately the sum of the source files.

Can I merge a GIF with a static image?

Convert the static image to a single-frame GIF first using Images to GIF, then merge it with your target GIF.

Is my original GIF modified during merge?

No. New combined GIF is created in your browser. All source files remain unchanged.

Can I merge GIFs side by side instead of sequentially?

Sequential (end-to-end) merging is supported. Side-by-side layout is not yet available but may be added in a future update.

GIF Merge

Combine multiple GIF animations into one. Files play sequentially, one after another.

Upload GIFs to Merge

Drag & drop or click to select multiple GIFs

Combine two or more GIF files into a single sequential animation. Upload your GIFs, arrange them in order, and export the merged result — all processed locally in your browser.

Great for concatenating reaction clips, stitching together chapters of an animation, or assembling a multi-scene loop. Frame delays from each source GIF are preserved exactly.

Guide: Combining GIFs

When to use it

Turn two reaction GIFs into a single reaction that plays back to back.
Bundle short step-by-step GIFs, like a mini tutorial, into one file that plays in order.
Share one GIF instead of posting several separate files on social media or in a chat.

Tips for a clean merge

Check the merge order after uploading. The GIFs play one after another in the order shown in the list.
GIFs with similar dimensions combine most naturally. If the sizes are very different, match them first with GIF Resize.
If one clip feels faster than the other, even them out with GIF Speed before merging so the transition looks smooth.

Good to know

Because every frame from every GIF is kept, the merged file can be larger than the originals. If it gets too big, shrink it with GIF Compress.
Want the GIFs to play at the same time instead of one after another? Use GIF Side by Side or GIF Stack.
Everything runs in your browser. Your files are never uploaded to a server.
