RenderX, Inc is a commercial software development company that provides standards-based software products, used for typeset-quality electronic and print output of business content. RenderX develops products that convert XML content into printable formats such as PDF, PostScript and AFP.


RenderX started as a company to promote open standards in general and XSL-FO in particular, participating in a contest announced by Sun and Adobe.[1][not in citation given] Later the contest was cancelled but the company decided to proceed anyway.[citation needed]

Contribution to XSL-FO community[edit]

The company has devised a DTD for XSL-FO documents[2][3] and holds three patents of converting XML to PDF.[4][5][6] RenderX is one of the 335 members of the World Wide Web Consortium[7] and a contributor[8] to OASIS.


RenderX's main product is a Java-based XSL-FO formatting engine called XEP, which converts XSL-FO documents to printable form (PDF or PostScript). XEP is free for academic and personal use.

XEP conforms to Extensible Stylesheet Language (XSL), a W3C recommendation. It also supports a subset of the Scalable Vector Graphics (SVG).
