 Welcome, {{#ifanon:anonymous|registered}} user.
+[[Wikipedia:Scalable_Vector_Graphics|SVG]] is a simple xml markup system for describing images. (Well, simple for the trivial stuff I'm using it for...)  You just tell it "I want a blue circle here, a red square there, ...". Unlike a bitmap, this will render perfectly at any scale. But obviously you need software to turn it into bitmap of the size you need.  The wiki will do so itself, but I'm not quite sure if it renders it for each size, or if it renders it once on upload and just rescales the bitmap.
+There are some online convertors you can use. Just google.
+If you want to do it locally, one free application (both windows and linux) is [[wikipedia:Inkscape|Inkscape]]. You can either load the svg file interactively and then export via the menus, or use a command line:
+ inkscape -w 1024 -h 1024 input.svg --export-filename output.png
+Another free command-line tool is [[wikipedia::ImageMagick|ImageMagick]]
+ convert -size 1024x1024 input.svg output.png
