ANSWER: Adobe Acrobat Distiller, sometimes know as "Adobe Distiller," is a software application that lets you create PDF files from other types of files. A common use for Adobe Acrobat Distiller is creating PDF files from PostScript files. That is: if you have a PostScript file, you can use Adobe Acrobat Distiller to create a PDF version of it.
