DoPDF let’s you convert any printable file that you have into a PDF in seconds. Yes, that includes docs, xls, ppt, txt, html or even image files such as jpg or png. It’s a lightweight program, which acts as a virtual printer on your PC.
When you have a document that needs converting, simply print it using the doPDF engine installed as a printer (that’s File>Print in most cases for PC) and instead of the hardcopy document, you get the virtual PDF document. You get to choose the paper size, dpi and all the options that a standard printer offers, and it applied these settings to the printed PDF.
