Vector vs Raster Images
Vector vs. Raster: Whatβs the Difference?
Vector and raster are two ways of building an image. The biggest difference is how they handle resizing.
| Feature | Vector | Raster |
|---|---|---|
| Built from | Mathematically defined lines, curves, and shapes | A grid of tiny colored squares called pixels |
| When enlarged | Stays sharp at any size | Can look blurry or pixelated |
| Best for | Logos, lettering, icons, and cut-ready designs | Photographs, detailed textures, and digital paintings |
| Common formats | SVG, AI, EPS | JPG, PNG, TIFF, PSD |
| Editing | Individual shapes and paths | Pixels, selections, and layers |
| Resolution | Resolution-independent | Depends on pixel dimensions and output size |

For graphics work, keep logos and lettering as vector originals whenever possible. The same design can scale from a small decal to a large sign without losing sharpness, and vector paths are typically needed for vinyl cutting.
Raster is the better choice for photographs and richly textured artwork. For printing, around 300 pixels per inch at the final print size is a common target for close-viewed work, though large signs viewed from farther away can use less.
Two important catches: saving a JPG as an SVG doesnβt automatically turn it into true vector artwork, and a PDF can contain vectors, raster images, or both. The file extension alone doesnβt guarantee that a design will enlarge cleanly.
