XSL FO Rendering Online is a Web-hosted service that lets you convert XML documents into PDF files that anyone can view using the free, widely distributed Adobe Acrobat Reader. Your documents will look exactly as you wanted them to and will be accessible to anyone across a wide range of hardware and software. The supported formats are XSL FO, DocBook and XML+XSL file pairs.

The first step is making an XSL FO file. This step is ignored if a prepared XSL FO file has already been input to the service. Otherwise we convert the XML file to XSL FO format using the stylesheet specified by the user.

The second step is rendering a printable file. The source document for this step is the XSL FO file prepared at the previous stage or specified by the user.
