Introducing macSVG

(Project update, October 2017 – macSVG v1.1 development is underway, and will feature improved editing features for nested transforms, especially rotate transforms with a new center-of-rotation handle that can be edited in the web view, and a new plugin to generate a path from a user-specified text string and font.  Check back soon for an application update.)

macSVG is a MIT-licensed open-source macOS application for designing and editing Scalable Vector Graphics (SVG) content for HTML5 web pages, mobile apps, animation design, and general graphics usage.

SVG is an open-source format for computer graphics documents based on the authoritative Scalable Vector Graphics (SVG) 1.1 (Second Edition) – W3C Recommendation 16 August 2011 from the World Wide Web Consortium (W3C), and is supported on most modern web browsers, and many application frameworks.

macSVG can produce dynamic, high-quality graphics and animation for HTML5 web views that can be displayed on most major desktop and mobile platforms, including iOS, Android, macOS, Microsoft Windows and Linux.  This video shows an example of SVG animation in macSVG:


For many web pages, SVG documents are a good alternative to other image formats like JPEG, PNG, GIF, Animated GIF, Adobe Flash, and videos.  SVG documents are mostly based on vector graphics, and the file sizes can be much smaller with no loss of quality or detail at any scale or resolution.  An SVG document can also contain contain JPEG and PNG images, so it can blend vector graphics with raster images.

The inspiration for the macSVG project was provided by an essay from April, 2010 – Steve Jobs: Thoughts on Flash.

The macSVG project would not be possible without the pioneering work of the developers at and Apple, Inc., and many other software developers.  Their work is gratefully acknowledged in this homepage for the macSVG project.
