Vector

Vector graphics are a form of digital illustration based on mathematical formulas that define points, lines, curves, and shapes, allowing them to be scaled infinitely without losing quality or increasing file size. Unlike raster images composed of fixed pixels, vectors use paths defined by mathematical equations to create artwork that remains crisp and clear at any size. In professional design platforms like Snapied, vector graphics are essential for creating logos, illustrations, icons, and other scalable elements that need to maintain quality across various applications from business cards to billboards.

The technical foundation of vector graphics lies in Bézier curves—mathematical expressions that define smooth curves between points, with handles that control the curve's direction and shape. These curves combine to create paths that can form any shape, from simple geometric forms to complex illustrations. Each path can have attributes like stroke (outline) color and width, fill color, and various effects. Because vectors store only the mathematical information needed to draw shapes rather than data for every pixel, they typically create smaller file sizes than equivalent raster images, particularly for graphics with large areas of solid color or simple shapes.

In professional design workflows, vector graphics serve numerous essential purposes. They're the standard format for logo design, ensuring brand marks remain sharp across all applications regardless of size. They're ideal for illustrations that require clean lines and solid colors, from simple icons to complex infographics. They're used to create custom typography and lettering that can be resized without degradation. In print design, vectors ensure high-quality reproduction at any scale, while in web and app design, they're often used for interface elements and illustrations that need to adapt to different screen sizes and resolutions. Modern design often combines vector and raster elements—using vectors for graphic elements that benefit from scalability and precision, while using raster images for photographs and texture-rich illustrations. Common vector file formats include AI (Adobe Illustrator), EPS (Encapsulated PostScript), SVG (Scalable Vector Graphics for web use), and PDF (which can contain both vector and raster elements). The ability to create, edit, and properly implement vector graphics across different media is a fundamental skill for professional designers, ensuring their work maintains quality and flexibility throughout the production process.
