The Full form of PDF is Portable Document Format.

What is PDF?

The Portable Document Format (PDF) is one of the most popular file formats developed by Adobe Inc. (previously Adobe Systems Incorporated) in 1993 for presenting documents, including formatted texts and graphics, in a special way that does not depend on application software, hardware, and operating systems.

In other words, this is one of the finest means by which one can easily view, navigate, print, or forward all the elements of a printed document as an electronic image independent of the application software, hardware, and operating systems.

PDF files are usually created using Adobe Acrobat, Acrobat Capture, or analogous applications.

PDF files are particularly beneficial for copy-edited or type-set documents like magazine articles, product brochures, or flyers in which one desires to exactly preserve the original design of the texts and graphical elements online. A PDF file may be made up of single or multiples pages, or images, each of which one can easily zoom in on or out for better reading and viewing experience. One can also go to previous or next pages using page forward and backward options.

Technical elements of PDF

PDF files may comprise of various contents in addition to flat text and images. The contents cover a diverse range that includes logical structuring elements, interactive elements like annotations and form-fields, layers, rich media (including video content) and three-dimensional objects, and numerous other data formats. The PDF specification also offers options for encryption and digital signatures, file attachments, and metadata to allow workflows, which requires these features.

The PDF file system is a combination of three technologies.

A subset of the PostScript page description programming language, which is used to create the layout and graphics.

A font-embedding/replacement system that helps in embedding the used fonts to travel with the documents as a portable object.

A structured storage system to combine all these elements and other accompanying contents into a single file, with data compression whenever required.

Advantages of PDF

The integrity of visual elements

The PDF file system is created to display the same content and layout independent of the operating system, device, or software application used for viewing.

Supports interactive contents

The PDF format permits one to assimilate several types of content – text, images, and vector graphics, videos, animations, audio files, 3D models, interactive fields, hyperlinks, and buttons. All of the elements can be integrated within the same PDF file and structured as a report, a presentation, or a portfolio.

Portable

PDF helps mobility and portability. One can view a PDF file anywhere using free or paid tools like Adobe acrobat reader, Foxit PDF reader, etc.

Secured

PDF file format offers options to set up different levels of security to protect the content and the whole document, such as watermarks, passwords, or digital signatures.

Allows file compression

While PDFs can hypothetically contain an unlimited amount of information, they can easily be compressed into a smaller file size that helps in sharing with full control over the level of image quality.

Disadvantages of PDF

Difficult to edit

PDFs are hard to edit and it is sometimes even harder to extract information from the PDFs. It is easier to edit files in other formats than in PDF since PDF files need to be edited in specialized programs.

Hard to copy elements

It is also problematic to work with text in PDF files. It is often very difficult to even copy a fragment of a PDF file, as the texts are also perceived as a picture.

Web page integration

PDF files are not always fully integrated into Web pages. Only when the user has an Adobe Reader or other PDF reader plug-in installed, PDF files can be viewed within the Internet browser. But, without pre-installed plug-ins, one has to download the file and view it in a separate application.

Various types of PDFs

Although one can easily create a PDF using the same click and select methods every time, how one inputs the information to generate them can vary a lot. It generally affects how certain viewing and converting functions work.

There exist two types of PDF namely native PDFs and scanned PDFs. A native PDF is a PDF that is created from an electronically processed document. A scanned PDF is one that is generated by scanning a physical paper document using a scanner.
