The IAN symbol libraries currently contain 3042 custom made vector symbols designed specifically for enhancing science communication products with diagrammatic representations of complex processes. You can download them individually, or as an entire package in AI, SVG, or PNG formats.

AI version is for Adobe Illustrator and provides the symbols as palettes within the Illustrator tools. This is the best option if you have Illustrator.

SVG version is vector (fully scalable) and is the best option if you have other vector compatible software. The palettes format works with Inkscape's Symbol Dialog feature.

PNG version is convenient if you don't have any experience with vector editing software.

* can be imported into MS PowerPoint and Word, or edited with Adobe Photoshop etc

The zip package can be unzipped anywhere. The symbols in this version are raster which is great for quick use in documents, but they are not easily editable or scalable.




Simply open each file directly in your graphics software.


Illustrator (AI)

The symbols are accessed via Window > Symbol Libraries > IAN Symbols.

NOTE: If you open the illustrator files directly, they will appear blank.



When opening a symbol from the SVG or AI palette versions, or via the image library import in the online diagrammer, you need to break the link to the symbol before it can be edited.

  • Illustrator: Right click > Break Link to Symbol
  • Inkscape: Edit > Clone > Unlink Clone

You may also need to ungroup the symbol (often a few times) to be able to access all elements in the symbol.
