PDF file, which is a wide range of file types, such as the transfer of electronic documents between enterprises. It is because of the breadth of this type of file type that there is a need to convert various files into pdf format. Let's take a look at the methods and advantages and disadvantages of converting a file to a pdf format. (Image source network) [Office software itself saves as a function conversion] Now most office software can convert its own file type into PDF file. For example, Word, excel, ppt, etc. in Office 2010. The conversion method is very simple, open the file menu, save as, and then select pdf to save in the file type. This type of software converts its own files into pdfs with high quality and complete content, such as hyperlinks that are not lost (multiple links can be found in PDF files). [Virtual Printer Conversion] The principle of this method is to install a printer on your computer, but this printer will create a pdf file when printing, and output the contents to be printed to a pdf file. There are many such virtual printers, there are free, there are charges, such as doPDF free. After the installation is complete, you can see this virtual printer in ”Devices & Printers" (win7 system). When we need to convert the file, we only need to open the converted file, then print the file. Next, when selecting the printer, select the pdf virtual printer. In the process of conversion, you can also choose options such as quality, font embedding. The higher the quality, the clearer the result. The purpose of embedding fonts is to prevent garbled characters from appearing when there is no corresponding font on the target computer, or to display fonts that are not what we want (deformation). But improving quality and embedding fonts can greatly increase file size. The advantage of using a virtual pdf printer is that it does not need to parse the converted file format, and the conversion range is wide, as long as the content that can be printed can be converted, such as web pages, pictures, word documents, and the like. But the disadvantages are also obvious, such as low conversion quality and loss of information (such as hyperlinks); because it is an analog printer, it must be printed to "paper", when the length of the printed content is mapped to the target paper length and width, it is possible Causes deformation. In addition, when downloading and installing such a program, it is necessary to distinguish between 64-bit and 32-bit, because the driver of the virtual printer needs to be installed on the computer, and the 32-bit driver cannot run on the 64-bit system, and vice versa. Of course, after downloading the software, there are two kinds of system driver support, so we don't have to worry about it. [Other methods] There is also a professional pdf file conversion tool on the Internet. This software needs to parse the converted file format, so the quality is uneven. It is really not easy to find a good one. I will not introduce this article here. [System Home] www.xp85.com Related articles recommended: 1.
