Graphic design is an ever-evolving field that relies heavily on a wide variety of file types to create, store, and share designs. Understanding these file types is crucial for designers, clients, and anyone working within creative industries. This guide will cover the most common graphic design file types, explaining their uses, advantages, and limitations. By the end of this guide, you will have a comprehensive understanding of these file types and how to best use them in your projects.
Raster vs. Vector Graphics
Before diving into specific file types, it’s essential to understand the two primary categories of digital graphics: raster and vector.
Raster Graphics
Raster graphics are made up of pixels, tiny dots of color that form an image. The quality of a raster image depends on its resolution, typically measured in dots per inch (DPI) or pixels per inch (PPI). Higher resolution means more pixels and finer detail. However, raster images lose quality when scaled up.
Common raster file types:
JPEG (JPG)
PNG
GIF
BMP
TIFF
PSD
Vector Graphics
Vector graphics use mathematical equations to create shapes and lines, making them infinitely scalable without losing quality. They are ideal for logos, icons, and any design that needs to be resized frequently.
Common vector file types:
SVG
AI
EPS
