Rasterize Files and Vectorize Files

First of all, the definition of a vector file should be mentioned. In short, the mathematical formula creates some points on a grid, and those points are connected with lines and curves, and those lines and curves compose the shapes on the vector graphics. There is no need to inquire thoroughly about how the mathematical formula works. All in all, the vectorized image can be enlarged to the original scale without losing quality.

In contrast with vector files, rasterized images cannot keep the high resolution if it's enlarged beyond the original size. This is because the raster files are composed of some color blocks, which are known as pixels. As the pixel number that forms an image is fixed, the pixel will also be enlarged when you zoom in on the picture. Although this feature seems inconvenient for you to view the raster images, it could be friendly to your printer.

In addition to that, rasterizing the image is important for designers who need to submit their drafts to others to review. They can protect their intellectual property as the rasterized drafts cannot be print out as clearly as using a vector file. That is why you should rasterize PDF if you are going to send it to someone who is not very trustworthy. And the following parts of this post will focus on the methods of rasterizing PDFs, and you can follow them if you find it's helpful.
