Vexel is a neologism for an entirely pixel-based form of raster art that imitates the vector graphics technique, but is distinguished from normal vector graphics or raster images. The word itself is a portmanteau derived from a combination of "vector" and "pixel." It is an entirely pixel-based raster image that imitates the vector graphics style
The popularity of vexels stems from the fact that traced vexel requires little drawing ability.

While "vexel" is used and accepted in a relatively narrow, self-described "vexel" community, the art and general worlds have not embraced it as warmly, mostly because it refers to a body of work mostly revolving around DeviantArt and Vexels.Net and because of the workflow by which most vexel art is created.
