title: How to convert the font objects in a PDF to CFF
body: <p>PDFs which use CFF fonts instead of Type 1 fonts are much smaller. Running a PDF through a ghostscript conversion will indeed produce a PDF with Type1C (CFF) fonts. But this also "re-renders" the PDF, getting rid of certain factors such as the print/screen distinction (if used). It there any way to convert a PDF with Type 1 fonts to a PDF which is otherwise identical, but which uses Type1C fonts instead, i.e., just converting the font objects?</p>
