How raster and vector graphics work, their strengths, limitations, and best use cases.

Every digital image falls into one of two categories: raster (bitmap) or vector. Understanding the difference is fundamental to working with digital graphics.

Raster Graphics

A raster image is a grid of pixels — tiny squares of color. Every photograph is raster. Common formats: JPEG, PNG, GIF, WebP, BMP, TIFF. Raster images have a fixed resolution; scaling up causes blurring and pixelation.

Vector Graphics

A vector image is a set of mathematical instructions describing shapes. The rendering engine draws them at whatever resolution the output device needs — always perfectly smooth. Common formats: SVG, AI, EPS, PDF.

When Raster Wins

  • Photography
  • Complex natural imagery
  • Screenshots
  • Pixel art

When Vector Wins

  • Logos at any size
  • Icons and UI elements
  • Typography (all fonts are vector outlines)
  • Charts, diagrams, maps
  • Print design at high resolution
  • Animation and interactivity

Converting Between Formats

Raster to vector: Shape to Vector traces pixel boundaries into vector paths. Works well for flat-color graphics. Vector to raster: Export from any vector editor at any resolution — always lossless at the target size.
