Raster image definition:

Raster files are composed of pixels, which are little color squares that can combine to create extremely detailed pictures like photos when used in large quantities. An image’s quality increases with its pixel count and vice versa. The type of file (JPEG, GIF, or PNG, for example) determines how many pixels are in an image.

Vector art definition:

Vector files use mathematical equations, lines, and curves with fixed points on a grid to produce an image. There are no pixels in a vector file. A vector file’s mathematical formulas capture shape, border, and fill color to build an image. Because the mathematical formula recalibrates to any size, you can scale a vector image up or down without impacting its quality.

Comparing the difference between raster and vector files:

Resolution is one of the primary distinctions between raster and vector files. A raster file’s resolution is expressed in either PPI (pixels per inch) or DPI (dots per inch). You can see individual pixels in raster images when you enlarge or zoom in.

Compared to vectors, raster files have a larger color spectrum, allow for more color tweaking, and exhibit finer light and shading; nevertheless, when downsized, they lose image quality. Increasing the size of an image is a simple method to determine if it is a raster or a vector. The image is probably a raster file if it starts to get pixelated or blurry.

Resolution is irrelevant when dealing with vector art files. Vectors can be resized, rescaled, and reshaped without any loss to the quality of the image.

Typically, raster files are used for digital pictures. Many digital cameras automatically create and save raster files; you will also often see rasters in the images you view online. Additionally, raster files are frequently used for image, photo, and graphic manipulation.

Complex images, digital illustrations, and logos are better suited for vector files. This is due to the fact that vectors may be enlarged without losing quality, making them appropriate for a broad range of printed formats.

In certain projects, vector and raster images are combined. For instance, a brochure might utilize raster images for the photos but vector drawings for the company logo.
