Kilobyte SVG Challenge

Make an accurate SVG of a logo, in 1024 bytes or less!


The purpose of the Kilobyte SVG Challenge is sixfold:

  • marketing SVG use on the web
  • teaching SVG, "view source" style
  • marketing and improving SVG tools
  • collecting great, fast, and tiny SVG logos
  • learning, and having lots of geeky fun doing it!


  • Viewed in a web browser, your SVG must scale to the window size and maintain its aspect ratio. How?

  • Quality trumps size – while 1k is a goal, don't sacrifice looks!

  • You are encouraged to improve on already submitted logos!

  • No raster data, data: urls or multi-file svgs.

  • One tag per line, indented one or two spaces.

  • Create a pull request:

    • Name it after your logo.
    • List original: <url> on the first line of your comment, linking a version of the logo on the web.

Best practices

  • Since one goal is teaching, think of your commits as a step by step guide:
  • When optimizing, make separate commits for different operations you do.
  • Write good commit messages about what you did, that others can learn from.
  • When using tools, you are encouraged to name them in your commit messages.
  • If it's a command-line tool, better still: paste your command line args further down in the message!


  • To make an SVG scale, make sure your <svg> element has a viewBox attribute, and no width, height or preserveAspectRatio attributes (xMidYMid meet is already the default).


  • InkScape: a popular open source SVG editor
  • Your favourite text editor - Emacs, vim, Textmate, et cetera
  • Scour [launchpad]: a python module / script by Jeff Schiller to shrink SVG file sizes
  • SVG Cleaner: a similar perl script with a graphical UI wrapper
  • SVG-Cleaner [github]: a javascript npm port of (parts of) Scour
  • svgtidy: a ruby script by Sam Ruby
  • CleanSVG: a .NET windows tool by Microsoft

If you find your logo represented here and would rather have people use whatever inferior non-scalable, slow-loading, pixellated raster graphics version they find when talking about you on the web, just submit an issue mentioning "takedown" in its title, list the url to the logo in question, and it will of course be removed from here.
