    Discontinued

    The official website no longer links to a download of the free Foxit PDF Creator, but only to Foxit's "new" all-in-one PDF solution, PhantomPDF. Therefore, there's no way to download PDF Creator at this time and development has almost certainly stopped in favor of working on PhantomPDF.
