Lower bitrate means less data is transferred and, thus, smaller file sizes. Many compression methods focus on the idiosyncrasies of human physiology, taking into account, for instance, that the human eye can see only certain wavelengths of light. The psychoacoustic model describes how sound can be highly compressed without degrading perceived quality. Flaws caused by lossy compression that are noticeable to the human eye or ear are known as compression artifacts.

Because SVG images are based on XML, text in .svg files can be searched, indexed, and scripted. Moreover, SVG files can be “losslessly” compressed, which means the exact original image can be reconstructed from the compressed version.
