What does saving an image in a vector format imply?

Saving an image in a vector format means that the image is composed of mathematically defined shapes and paths rather than pixels. This characteristic allows the image to be resized without any loss of quality. Unlike raster images, which can become pixelated or blurry when enlarged, vector images maintain their crispness and clarity regardless of size change. This is especially beneficial for graphics that need to be scaled up or down for various applications, such as logos or illustrations used in different contexts.

The other options describe limitations not associated with vector images. For instance, vector formats are designed for scalability, thus contradicting the notion of having a fixed resolution. Additionally, they offer flexibility and can be edited, rather than being uneditable.
