Methods and advantages and disadvantages of converting various files to PDF file format

PDF file, which is a widely used file type, such as transferring electronic documents between enterprises. Because of the breadth of this file type application, there is a need to convert various files to PDF format. Here's a look at the methods and pros and cons of converting files to PDF format.

"Save as function conversion for Office software itself"

Most office software now converts its own file types to PDF files. For example, Word, Excel, PPT, and so on in office 2010. The conversion method is simple, open the File menu, save As, and then select PDF in the file type to save.

This type of software converts its own files into PDFs, with high quality and complete content, such as hyperlinks that are not lost (hyperlinks can be found in PDF files).

"Virtual Printer Conversion"

The principle of this approach is to install a printer on your computer, except that the printer will create a PDF file and print it out to a PDF file.

A lot of this kind of virtual printer, there are free, there are charges, such as dopdf free. After the installation is complete, you can see this virtual printer in the "Devices and Printers" (Win7 system).

When we need to convert the file, just open the converted file, then print the file, then select the printer, select the PDF virtual printer.

In the process of conversion, you can also choose options such as quality, font embedding, and so on. The higher the quality, the clearer the result. The purpose of embedding fonts is to prevent them from appearing garbled when they do not have a corresponding font on the target computer, or to display a font that is not what we want (morph). However, improved quality and embedded fonts greatly increase file size.

The advantage of using a virtual PDF printer is that it does not need to parse the converted file format, the conversion scope is wide, as long as the content can be printed can be converted, such as Web pages, pictures, Word documents.

But the disadvantages are also obvious, such as low conversion quality and loss of information (such as hyperlinks), because it is an analog printer, you must print to the "paper", the print content is long and wide to the target paper length-width mapping can cause deformation.

Also, when downloading and installing such a program, you must distinguish between 64-bit or 32-bit, because the driver of the virtual printer needs to be installed on the computer, the 32-bit driver cannot run on the 64-bit system, and vice versa. Of course, some software download down, at the same time there are two kinds of system driver support, do not worry about us.
