Xara's PDF export tool creates super-clean, very compact PDF files. This includes support for graduated color fills, for flat transparency and graduated transparency.  And when you export as PDF everything remains pixel perfect, resolution-independent vector graphics*.

The PDF exporter has also been designed to allow the files to be opened by Adobe Illustrator®, so providing significantly improved Illustrator compatibility which means that vector artwork including graduated color and transparency can now be imported cleanly into Illustrator versions 9 onwards.

Xara Xtreme also offers reliable PDF import.

*PDF can only support the basic Xara graduated fill and transparency types of flat, linear and radial. Other graduated types are automatically rasterized (flattened) to any required resolution on export.
