High fidelity docx to PDF output/conversion
Docx4j’s standard method of producing PDF output is via XSL FO, using Apache FOP.
Docx4j can also produce raw XSL FO, which is useful if you want to:
• use some other FO processor, or
• use FOP to produce PostScript, PCL, PNG/TIFF or other of FOP’s output formats
There are however, limitations to the fidelity of docx4j's PDF output.
New as of February 2015, Plutext now offers a commercial docx to PDF solution which overcomes these limitations (by avoiding XSL FO). To try it, choose a doc belowx, and press the upload button. Alternatively/better, access the converter server directly.
