How can you make multiple pictures into one?

I downloaded several pictures (I don't know if it's spelled correctly). I would like to make this a picture. For example, 4 pictures arranged in a square. Can someone help me there?

I have a Huawei Psmart 2019. Does anyone know about it?

Download a "collage" app from the app store

"Downloaded" would be correct.

You can do it on your cell phone with any photo collage app that is like sand by the sea.

You can download PicsArt for free. There you can't only make the pictures one, but also much more!

I did it. How do I get them from the app's album into my own gallery?

There must be an image upload button somewhere (in the app)

I do not find. What app do you have?

* PicsArt is a good app you can do anything with pictures,

* Layout from Instagram you can remix multiple images
