GIF Merger - Free Online | FunToolX

Upload multiple GIF files, drag and drop to sort to determine the playback order. You can set the interval between each GIF (insert blank frames or keep the last frame still) and whether to unify the output size of all GIFs. Click Merge and wait for the encoding to complete, and download the spliced GIF.

The tool decodes all frames of each GIF in turn on the browser side and spliced them into a frame sequence in order. If the input GIF size is different, it will automatically scale to a uniform size (based on the first or largest). Inter-frame spacing is achieved by inserting blank frames or extending the delay of the last frame. All processed locally.

It is suitable for splicing multiple short GIFs into a continuous animation, such as making multi-step tutorial animations, serial emoticons, or combining different clips into a complete story animation.

The online GIF merge tool joins multiple GIF animations end to end into a long animation. It supports adjusting the interval time and unifying the size, and handles it locally in the browser.
