Therefore this time we will explain the overview of PDF advantages and disadvantages, how to create it, and how to view it. What are PDFs? PDF stands for "Portable Document Format" and refers to a file format that can store data similar to a document printed on paper. Non-PDF data such as Word, Excel, and Photoshop cannot be viewed without the same software, and even compatible viewers may not reproduce the data perfectly. However, if it is a PDF format file, you can share the data as it is even if you open it with another terminal or software. PDFs are often used for manuals, instructions, reports, invoices and receipts, etc. If you print these on paper, the number of sheets will increase, and the cost will increase accordingly. PDF on the other hand reduces costs and distribution effort.
History of PDFs PDF began in 1991 when Adobe founder Dr. John Warnock attempted to transform information from paper to digital. Development was carried out with the goal of enabling display and printing on any PC or application. Then, in 1992, PDF as we know it today was born and spread mobile number list all over the world. Advantages of PDFs Here are four advantages of PDF. Fonts and layouts are hard to collapse . With files in other formats, fonts and layouts often collapse due to different devices, OS types, and software versions. In order to share data, both sides must have almost the same environment. A PDF that can save the same state as when printed can easily clear this problem. It is a file format that is useful not only for sharing but also for storage.
However there are exceptions for a small number of them, and sometimes they fall apart. Passwords and certificates can be given If you set a password for the PDF file, you can restrict viewing to only those who know it. In addition, security can be further strengthened by assigning a certificate (digital ID). A digital ID is like an identification card and contains information such as the owner's name, expiration date, and digital signature. Another benefit of PDF is the ability to increase file security. small size of data The third is that the data size is small. Compared to files such as Word, Excel, Illustrator, etc., it is only a fraction of the size. However, when attaching to an e-mail, additional PDF compression software may be used to further reduce the file size. It can be easily created with Office software, browsers, etc. No special software is required for PDF creation, and can be output using Office software or browser functions.
