Advantages of PDF File Format

The PDF file format has many advantages, for example:

1. Fonts are embedded in PDF files. Therefore, the PDF files can be opened throughout various programs, hardware, and operating systems, while the layout and style will not be messed up.
2. Multimedia can be embedded.
3. It supports vector graphics. Therefore, zooming in and out will not affect the clarity.
