What is the key difference between raster and vector graphics?

The key difference between raster and vector graphics lies in how they are constructed and rendered. Raster graphics are made up of pixels, which are tiny squares of color that combine to form images. This means that raster graphics have a fixed resolution and can lose their clarity and become pixelated when scaled up. Common formats for raster graphics include JPEG, PNG, and GIF, which are typically used for photographs and complex images that require rich detail and color variations.

In contrast, vector graphics use paths defined by mathematical equations, which allows them to be infinitely scalable without losing quality. This scalability makes vector graphics ideal for logos, icons, and any design that requires clean lines and crisp details at any size. Formats for vector graphics include SVG, AI, and EPS.

Understanding this distinction is critical for graphic designers since the choice between raster and vector can significantly impact the quality and usability of images for different projects.
