Most images on the web such as JPG, PNG, and GIF are raster images – grids of pixels that each hold a color value. Raster images are great for photos of real people and events, but they have drawbacks. When you scale a raster image up or down in size, you’re losing data and/or clarity in the image. Color intensity can also be lost in conversions and compression, leaving you with a mangled version of what you once wanted. A great alternative for many situations is to use vector graphics. Inkscape is a powerful free vector drawing program for Windows, Linux, and Mac, and this guide will get you started with using it to create your own smooth, colorful, scalable graphics.
