The full name of PDF is "Portable Document Format", and the Chinese meaning is "Portable Document Format" or "Portable Document Format". Its advantage is that it is universal regardless of whether it is Windows, Unix or Apple's MacOS operating system.
The PDF format was designed and launched by Adobe. Portable Document Format is translated into Chinese as Portable Document Format. In the 1990s, when Adobe first designed this file format, its main purpose was to compete in the field of cross-platform file formats and realize the dissemination and sharing of documents on different platforms.
In the early days, this format was exclusively used by Adobe and was not open to the outside world. Even Adobe Reader, the reader for viewing PDF files, is not free.
By 1993, Adobe decided that the PDF specification could be used freely. After that, until the ISO (International Organization for Standardization) officially authorized the release in 2008, anyone could create, read, and write PDF without paying royalties to Adobe. , Adobe holds a patent on PDF, but licenses other companies to develop applications that comply with PDF specifications in the form of a buyout license.

Advantages of PDF format documents:
1. Portability
The PDF file format is portable. Meaning we can transfer or move files without worrying about any dependencies. There are no missing fonts like in a Word document, or missing images in a PPT presentation. Once a PDF file is created, it can be easily shared with anyone* and the fonts, images, tables and formatting it contains will be moved with it.
2. Reliability
The PDF file format is reliable. When you create a PDF file containing any amount of data (such as paragraphs, images, vector graphics, tablets, etc.), it will display the data in the exact same way no matter where you view it. PDF is a reliable format for exporting documents to be shared with others or published publicly so that your message is conveyed in exactly the same way as intended.
3. Universal compatibility
Since the PDF file format became an open standard in 2008, it has been widely supported in various applications. Most modern browsers are fully capable of opening and displaying PDF files, and most modern operating systems come with basic pre-installed applications that can easily open PDFs. Therefore, the same PDF file can run on Windows, Mac or Linux and look exactly the same.
On Mac we can also use PDF Expert to get a better reading experience, because it can also be used as a simple application to open and read PDF files, not just a professional editor .
4. Easy to create
One of the main reasons why the PDF format is popular today is that it is easy to create. The vast majority of applications allow you to convert your current file as a PDF, allowing you to easily copy, share or transfer PDF files anywhere. Even using Microsoft's Word, Excel or PPT applications, you can export documents to PDF on Mac and then read them in PDF Expert.
