Here are 3 free websites to merge animated GIFs.
Although there are many online tools and software available to create animated GIF from still images, but what if you have to merge your favorite animated GIF images as a single animated GIF? In that case, these website can come in handy. Using these websites, you can merge two or more than 2 animated GIF images stored on your PC, and can generate single animated GIF to save to your PC. Apart from this, most of these animated GIF merger websites let you set animation speed, loop count, use online GIFs, output size, etc. You will also find some unique features, like delete frames from GIF, add delay time, set transition effect, and more. Have a look at these free websites to merge animated GIFs.
Online Image Editor comes with ‘GIF Maker‘ feature to merge two or more than two animated GIFs. Apart from this, you can also adjust the delay time for every animated GIF used in merging process. Another good feature that comes here is that you can set the transition for every single GIF. 16 different transition effects are available to choose from.
After selecting the transition effects and delay time, you can generate a single animated GIF using Create Animation! button. Before saving the animated GIF, you can preview it. That will help a lot to check if your animated GIF is good enough or you need to select different transition effect(s) and delay time.
To merge animated GIFs, you can use local GIFs, online GIFs, or both. This is really one of the best website in this list to merge animated GIFs. You can also use this website to crop and resize images (including animated GIF), add text to GIFs, overlay images, convert images, etc.

Animine.com is another great website in this list to merge multiple animated GIFs to create a single GIF. It might not work well for animated GIFs with hundreds of frames, but for small size GIF images, it works perfectly.
One special feature comes with this website is that you can also delete unwanted frames from added GIF files and generate single GIF. Before downloading the animation, you can preview it in actual size, and can save it to PC. Many other features are also available in this website, like set background for transparent images, set loop count, automatically reverse the order of frames, etc. You can also sign up to this website to avail more benefits.
Animizer.net is a good website to edit animated images. However, you can also use it to merge animated images (including GIF and APNG) or still images. Apart from this, you can also set output file size, flip images, reverse animation, set loops, etc. Options to set animation speed, use transparent background, and change foreground & background colors are also available. However, you must be careful before setting the adjustments, otherwise output will not come as good as expected.
Animizer.net also comes with Assembler option using which you can directly merge animated GIFs without any additional changes. However, during my testing, the output was no good. This option works good for still images (PNG, JPG, ICO, etc.). So when you have to generate animated GIF using still images, you can use this option.
You may also check these free websites to crop animated GIF images without converting them to still GIF.
Among these free websites to merge animated GIFs, I would recommend you to use first website. However, if you have to remove frames from animated GIFs to generate the short length GIF, then you should try Animine.com website.
