How to combine multiple images on a page into one?

Question

css

In general, the point is that there is a certain constructor in which, when choosing different items, one image is superimposed on another, in the end, you need to make sure that they are all somehow combined into one with the ability to use it on the same page or with the ability to save it Images.
I googled a lot, I didn’t find anything useful, if you tell me which way to dig and what to look for, I will be very grateful :)

Answer 1

You can connect images either through canvas, or using some libraries based on it.
To get started, read about canvas, in any case it will come in handy.
