How to merge several gif files into one without losing the animation?

Question

Design

You need to merge several animated gif files into one gif or video file with the animation preserved. Preferably without complex solutions like photoshop, if anyone knows, maybe there is an online service with such functionality?

Answer 1

I use SGM to combine gif animations, it is possible to change, set the transparency of the loaded gif. You can upload an unlimited number of files if you save them locally, saving gif and webm formats is supported, but the maximum size in px of the saved file is 600x600 px
