How to combine multiple GIFs into one animation
Combining GIFs into a single animation is useful for creating reaction compilations, step-by-step tutorials, before-and-after comparisons, and seamless looping sequences.
How GIF merging works
Each uploaded GIF is decoded frame by frame in your browser. All frames are collected in the order you've arranged, then re-encoded into a single animated GIF. Frame timing (delay) from each original GIF is preserved — so fast animations stay fast, and slow ones stay slow.
What happens with different-sized GIFs?
If your GIFs have different dimensions, the merger uses the first GIF's canvas size as the frame. Smaller GIFs are centered with transparent padding; larger ones are centered and cropped to fit. You can also switch to 'Scale to fit' mode which resizes all segments to match.
When to merge GIFs vs make a video collage
Merging GIFs is ideal for linear sequences — reaction chains, tutorial steps, story sequences. For split-screen or grid layouts, consider a video editing tool instead. The merged output preserves the GIF format, making it easy to share on social media, Discord, and messaging apps.
