PDF gives the impression that this format of the document can not be modified. But not many people want to know what PDF means. Let's see what PDF is.
Take a look at Baidu Encyclopedia:
The Portable Document Format (PDF) is a file format developed by Adobe Systems that is independent of applications, operating systems, and hardware. PDF files are based on the PostScript image model, which guarantees accurate color and printing on any printer. PDF faithfully reproduces the manuscript's characters, colors,combine pdfs for free windows and images.
As a result of the above explanation, let's take a closer look at each of its four characteristics:: 1.
The ability to be versatile
Various operating systems, such as Windows, Mac, Unix, and Android, must improve their individual requirements for document formats. For example, the Windows system cannot open MAC page format files. It should be noted that the technical document format of PDF is not dependent on any particular management system platform. This means that in the realm of online business or national electronic design documents, we can easily view PDF files without any constraints from a control system service platform. As a result, many entities in countries similar to ours opt for using PDF format to distribute materials such as books and product production information.
Format standards that are high-end and consistent
The situation is often encountered. When you open a document produced by a different version of the software, text and formatting paragraphs often appear to be big or small problems, and PDF files can contain text, fonts, formatting, color, and independent of the device and resolution of the graphic image encapsulated in the file, ensuring a consistent format across a variety of systems and software versions.
A perfect viewing experience for 3
Most e-books we find on the Internet are in PDF format, as you can see. There are two major reasons for this. The first reason is the second point above, the second reason is that PDF-produced e-books have the texture and reading effect of the paper book, you can vividly display the original book, the display size can be adjusted arbitrarily, giving the reader a personalized way of reading.
Not editable,
Typically, our contracts and important notifications are shared as pdf files. This is due to our higher requirements for this document type. Our goal is to maintain uniformity in the format and prevent easy modifications. The original intention of PDF design was to restrict editing capabilities. While it's understandable that PDF content appears as an uneditable image, sometimes even text in non-image form cannot be modified. This is because the text is stored with properties unique to objects, making it unrecognizable as normal text. To work around this, many people use third-party OCR software to recognize the text. However, this method may result in coding or formatting errors if the document's text resolution is not high enough.
Where can we use PDFs in our daily management work?
It is necessary to manually fill in some of the basic content after printing the company's contract documents, since this document cannot be changed.
If you don't know the other computer's operating system platform or software version, you can transfer files directly via PDF.
