- Vector formats support more colors than raster formats
- Vector files are always smaller in storage size
Correct answer: Vector graphics can be scaled to any size without losing quality
Vector graphics are defined by mathematical paths rather than pixels, so they scale infinitely without pixelation, making them ideal for logos and icons.
