There are two main kinds of image types: raster images and vectors. Raster images are the typical images made up of pixels that we all are familiar with.
But what is a vector and why would we want to use it? I'll do my best to explain it in this post. If you have any questions after reading, feel free to get in touch!
Normally, the photographs we take and the images that we see online are raster images: they are formed by many small squares -pixels-, each containing a specific color. When a lot of them are arranged together, they form an image.
Vectors, on the other hand, aren't made of pixels. They are made of mathematical equations.
