What Is PDF? Usage Guide, Differences And Best Tool

The revolution of this world is amazing because we are moving closer to technology and adopting the new changes side by side. From paper to paperless, documents and files have transformed digitally. We have a more efficient way to edit, store, and organize our documents which is the PDF.

Many people don't know what PDF stands for, but we have discussed what it abbreviation and what PDF means in this article.

Part 1: What is a PDF and How to Use it?

Since the world has gone digital, people tend to work with ease and efficiency. Office work is usually all about files and documents, so people have shifted to PDF file format as it is a quick way of reviewing and sending a file. For a better understanding of a PDF file, let's start with a question, what does PDF stand for? A PDF stands for Portable Document File, which was created by Adobe in the 1990s for multiple uses.

A PDF is full of different editing options as it contains different images, hyperlinks, text, videos, forms, interactive buttons, etc. A PDF file format is maintained by International Organization for Standardization, so there are many options through which you can open a PDF. For example, it can be opened on a browser, third-party apps, or Adobe Acrobat Reader. PDF files are compatible with macOS, Windows, and mobile devices, so you can use any web browser to view them. Other than that, you can also use a PDF reader like Adobe Acrobat to read your PDF file.

If you still need a separate PDF file viewer, several browsers come with PDF readers like Mozilla Firefox, Microsoft Edge, and Google Chrome. They work well as a PDF reader and have a fast speed, so you do not face any delays in reading or editing a file.

Part 2:  What is the Difference Between a PDF and a Doc?

There is no doubt that both PDFs and Docs hold a large amount of information, but both were created differently and by different software companies. Doc, which is mainly an extension of Word Document, was created by Microsoft, whereas PDF was created by Adobe Systems in the 90s. With that, they have their own set of differences, like a PDF file can be protected by a password and doesn't allow editing. On the other hand, a Doc doesn't have password protection, and anybody can edit it.

If you have an important PDF file to read, you require a PDF reader like UPDF for that, but to read a document, you would need KWord, AbiWord, MS Word, etc. A PDF has multiple benefits, like it provides services of combining 2 or more files and formats, high-quality printing, etc.

In comparison, a Doc helps in editing and reusing images and text. Also, if you are a Windows or Mac user, then you can easily use PDF for your work; it is also compatible with mobile devices and Linux. But Doc is only accessible in the systems that have word reading software.

Part 3: What is the Difference Between PDF and PDF/A?

In some cases, when you have to store important files and information that is useful in the future, you can simply archive it to use later. A PDF has a special kind of format system that is known as PDF/A, which is specifically used to archive files. In comparison, a simple PDF doesn't have the function of archiving files. With that, it is also important to know that PDF/A is a part of PDF which cannot be encrypted. On the other hand, you can protect your simple PDF file with a password.

When you access an old PDF file, there's a chance you'll lose data, but when you recover an old PDF/A file, the data is still there. If you are confused about what else is a PDF file used for? Then you must know that it allows graphical content like videos, audios, etc. But PDF/A doesn’t support any sort of graphical content.
