Instead of a collection of pixels which comprise a raster image, vector images are made up of sets of coordinates that represent shapes with color fills assigned. Because they are a description of how to create a raster image, rather than an actual raster themselves, true vector graphics can be rendered at any desired resolution with no loss in quality. Note that Derpibooru generates PNG previews of SVG files which are submitted at their nominal size, but keeps the original SVG file available for download.

If the submission is in the SVG format, or if the artist has made a SVG or AI file available at the source, please add the appropriate tag: ".svg available":/tags/-dot-svg+available or ".ai available":/tags/-dot-ai+available.

Additionally, please add the tag "transparent background":/tags/transparent+background if the background of the image is partly or wholly transparent (very common on vector images).
