What is Vector vs Raster Graphics?
The architectural distinction between resolution-independent mathematical path geometry (SVG, EPS, PDF) and fixed pixel grid matrices (PNG, JPEG, WebP).
Mathematical Formulas vs Pixel Matrices
Raster graphics store an explicit 2D grid of individual color pixels. Zooming into raster artwork exposes pixelation, blurriness, and jagged edges.
Vector graphics define shapes through mathematical coordinates, bezier curves, stroke widths, and fills. Rendering engines recalculate coordinates dynamically, providing infinite sharpness at any zoom or physical print size.
Key Advantages & Impact
- Infinite resolution independence across retina displays, billboard banners, and offset printing presses
- Dramatically smaller file sizes for logos, typography, and UI iconography
- Editable path layers and styling via CSS or client-side SVG manipulation

Frequently Asked Questions
Can a PDF file contain both vector and raster data?
Yes. PDF is a hybrid container format capable of displaying sharp vector typography alongside high-resolution raster photographs simultaneously.
Why not use vector graphics for continuous photographs?
Photographs contain irregular textures, grain, and millions of unique colors. Converting these to vector paths creates millions of anchor points, resulting in massive file sizes and sluggish rendering.
