Combine GIFs
Merge multiple GIFs into one — join them end-to-end in sequence, or arrange them side by side, stacked, or in a grid. Reorder freely. Everything runs locally in your browser.

Sequential plays one GIF after another. Layout shows all GIFs at once in a collage.
Horizontal places GIFs in a row, vertical stacks them, and grid tiles them.
Fit to first matches the first GIF. Fit to largest uses the max width and height among all GIFs.
Used behind contain-fitted frames and in layout gaps.
Space between GIFs in layout mode (0–40 px).
When GIFs have different lengths in layout mode, loop the shorter ones or freeze on the last frame.
GIF only supports binary transparency. Preserve keeps see-through areas; Solid fills them with a color you choose.
Transparent areas are filled with this color before encoding.
Lower sampling intervals keep more detail but may produce larger files and take longer.
Time between frames. Keep original timing, pick a preset, or enter a custom delay in milliseconds.
Enter a delay between 20ms and 10000ms. Applied to every frame.
How many times the GIF should repeat after the first play. Infinite loops forever.
gif.js style: 0 means infinite. For custom, enter how many extra repeats after the first play (0–100).
Combining many large GIFs or using a wide grid can increase memory use and encoding time in the browser.
About Combine GIFs
- • Join multiple GIFs end-to-end, or arrange them in a layout collage
- • Reorder GIFs before combining; layout supports horizontal, vertical, and grid
- • Adjust encode quality, loop, and transparency when exporting
- • All processing happens locally in your browser — files never leave your device
Combine GIFs guide
Combining GIFs means turning several animated GIF files into a single downloadable animation. Creators use it to stitch reaction clips, build comparison collages, or package multiple loops into one shareable file.
"GIF is a bitmap image format that supports animation through a sequence of frames with timing metadata."— MDN Web Docs – Image file type and format guide
- Sequential combine: append frames so clip A finishes before clip B starts
- Layout combine: place GIFs in a row, column, or grid that play at the same time
- Reorderable upload list so you control the final order
- Local browser processing with no server upload
OmniGIF Combine GIFs keeps the workflow private and free: decode locally, compose frames, encode with quality and loop controls, then download.
The tool loads each GIF into memory as frames with delays, then either concatenates those frames or composites them onto a shared layout canvas before encoding.
"Each image in the GIF data stream contains a Graphics Control Extension that can specify delay time and disposal method for that frame."— GIF89a Specification
- Upload: Add two or more GIFs and reorder them as needed.
- Choose mode: Sequential joins timelines; Layout builds a collage (horizontal, vertical, or grid).
- Tune fit & gap: Pick size fit or cell padding color, and gap for layout mode.
- Encode & download: Apply quality, loop, and transparency settings, then save the combined GIF.
Because frame delays are preserved when you keep original timing, the combined result keeps each clip’s pacing unless you override delay in encode settings.
Small prep steps help the merge look intentional and stay lightweight.
- Put the primary clip first when using Fit to first in Sequential mode
- Use a matching pad color so letterboxing looks deliberate
- Prefer Grid for 3+ GIFs when you want a collage instead of a long strip
- If files are large, trim or compress them first with OmniGIF tools
- Preview on desktop before encoding long Sequential merges
After combining, you can still crop, reverse, or compress the result with other OmniGIF tools.
Frequently Asked Questions - Combine GIFs
Upload at least two GIF files, drag to reorder if needed, choose Sequential (play one after another) or Layout (show them together), adjust settings, then click Combine GIFs. Download the result when encoding finishes. Everything runs in your browser.
Sequential concatenates animations in time: the first GIF plays fully, then the next, and so on. Layout places every GIF on the same canvas at once — side by side, stacked, or in a grid — so they play together.
No. OmniGIF decodes and encodes GIFs entirely in your browser. Your files stay on your device, which helps protect privacy.
In Sequential mode, frames are fitted with contain scaling into a shared canvas (fit to first or largest dimensions), with your pad color in empty areas. In Layout mode, each GIF is fitted into its cell the same way.
The output duration follows the longest GIF. Shorter GIFs can loop or freeze on the last frame — pick the behavior under Combine settings.
GIF Overlay stacks layers with free positioning on top of a background. Combine GIFs is for joining clips in sequence or tiling them into a collage without free-drag layer editing.
