Vector vs. Raster
When to Use Each Format
Understanding the difference between vector and raster graphics is essential for any designer. Here's your complete guide.
Vector
SVG, AI, EPS, PDF
Mathematical descriptions of shapes. Infinitely scalable without quality loss.
Scales to any size
Small file size (usually)
Editable with code
Not for photographs
Raster
PNG, JPG, GIF, WebP
Grid of colored pixels. Fixed resolution, quality depends on size.
Perfect for photos
Complex color/detail
Universal support
Gets pixelated when enlarged
Detailed Comparison
| Feature | Vector (SVG) | Raster (PNG/JPG) |
|---|---|---|
| How it works | Mathematical formulas | Pixel grid |
| Scaling | Infinite, always sharp | Limited by resolution |
| File size | Small for simple graphics | Grows with dimensions |
| Editing | Fully editable shapes | Pixel-level only |
| Color complexity | Limited gradients | Millions of colors |
| Photos | Not suitable | Perfect |
| Print quality | Always print-ready | Requires high DPI |
When to Use Vector Graphics
Use vectors when your graphic consists of shapes, lines, and text rather than photographs.
✓ Logos & Brand Marks
Need to work from favicons to billboards without quality loss.
✓ Icons & UI Elements

When to Use Raster Graphics
Use raster when you need continuous tones, complex colors, or photographic detail.
✓ Photographs
Camera images with millions of colors and subtle gradations.
✓ Digital Paintings
Artwork with complex textures and brush effects.
✓ Screenshots
UI screenshots and screen recordings.
✓ Complex Graphics
Images with thousands of colors or photorealistic elements.
