Need help identifying effect used on a picture

Question

I'm not a graphics designer, but I need some help with identifying the "effect" used on a picture. The picture I'm revering to is this one.

If anyone could help me naming the effect and tell me if there are any online sites that can recreate that effect with another photo.

Answer 1

This is simply "pixelation" (AKA "Mosaic")
