Vector vs. Raster: What’s the Difference (and Why Your Printer Cares)
If you have ever been told “we need your logo as a vector”, you have met the most important split in digital images: raster versus vector. Here is what it means, without the jargon.
Raster images are made of pixels
A raster image is a grid of tiny colored squares. JPG, PNG, WEBP, GIF, HEIC and most photos are raster. Each image has a fixed number of pixels, for example 800 × 600. When you enlarge it, the software has to invent pixels that don't exist, and the result looks blurry or blocky.
Vector images are made of instructions
A vector image stores shapes as math: “a curve from here to there, filled with this blue”. SVG, EPS, AI, PDF (with vector content) and DXF are vector formats. Because the computer redraws the shapes at whatever size you need, a vector logo looks equally sharp on a business card and on a truck.
| Raster | Vector | |
|---|---|---|
| Made of | Pixels | Paths and curves |
| Scaling | Gets blurry | Always sharp |
| Best for | Photos, complex textures | Logos, icons, text, illustrations |
| Formats | JPG, PNG, WEBP, GIF, HEIC | SVG, EPS, AI, PDF, DXF |
| Editing colors | Hard, pixel by pixel | Easy, one click per shape |
Why printers, sign makers and embroiderers want vectors
- Size: they print at sizes your pixels never planned for.
- Machines: vinyl cutters, lasers and embroidery machines follow outlines, which only vectors have.
- Color: each color is a separate shape, easy to match to a Pantone or thread.
How to turn a raster image into a vector
You can redraw it by hand in Illustrator or Inkscape, which is accurate but slow, or use an automatic vectorizer. Vexorio traces the shapes for you, lets you compare the result with the original using a slider, and gives you SVG, PDF, EPS and DXF in one download.
Rule of thumb: logos, icons and lettering should live as vectors. Photos stay raster.
