Why PDF is the Best Ideal Electronic Format

With the development of the Internet, all kinds of information need to be transferred and shared from one to one, but there is a huge problem in this process. For example, we may need to encrypt the document and then transfer to share, we may want to set different permissions for different use of personnel, receiver can be sure what kind of this file at the first glance, document can be printed to the output of high-quality pictures. To facilitate the user who doesn’t install the design software in his computer to view the file such as DWG, you have to convert AutoCAD DWG to PDF to view the drawing contains a 3D animation of the design; pay for e-book fees, etc. To solve these problems, a variety of formats of electronic documents, such as common Office documents, PDF, etc. come out .

Compared to Word, PDF does better as the cross-platform file format. In Windows systems, Word is stored to. Doc (or. Docx) format; to use the page file is stored in the MAC OS; other platforms, use the .odf format; and need to install different software. Similar to Word, DXF, a kind of AutoCAD file format, is weak in the cross-platform feature, so many designers have to convert DXF to PDF for sharing their designs on different computers.
