Definition and Benefits of PDF

PDF, which stands for Portable Document Format, was developed by the company that you’ve probably heard of, Adobe, in 1992. It didn’t gain recognition and popularity right away. This was due to the fact that you had to pay for the software to both view and create PDF documents. In addition to that, files tended to be of a large size and took up a significant amount of space, which led to some issues with loading and displaying them. Last, but not least – the external links didn’t work in PDF files back then. Eventually, Adobe fixed all of the major flaws and released a free version of the software, which resulted in PDF finally starting to grow in popularity.


Nowadays, PDF is one of the most commonly used formats. It can produce both vector and raster files. It has been an ISO 32000 standard since 2008.

Back in the day, Adobe wanted to create a format for opening and viewing documents on any device and OS. They had another requirement – there should’ve been no changes to the contents of files or their appearance. In other words, the layout, the formatting and other visual aspects of contents should’ve been preserved exactly the same.

Initially, PDF was created for the printing industry. Most printing hardware today supports it. Thanks to this, you can print your PDF files without special software.

PDFs can be opened via a variety of programs, but to this day, one of the most popular options is Adobe Acrobat Reader, which, as you might have guessed, was developed by the format’s creators.

PDF has a whole host of features. It allows to:

PDF supports RGB, CMYK, Bitmap, etc. There are also options for compressing bitmap content.

PDF is usually used to distribute a considerable amount of documentation. It’s recommended to opt for vector graphics as they produce the best results, and your files won’t have too large of a size. It is better to utilize fonts that are considered to be safe. In other words, these are more standard fonts, which the majority of existing software displays correctly – there are 14 of them to choose from. Newly developed fonts may cause some errors. For example, lines may shift or get distorted, pages may not have the proper look, etc.


Today, the Portable Document Format is unbelievably wide-spread. It is used everywhere: at home, at work, at school, and in various government agencies. Every person has come across this format more than once in their life. This is mostly because PDF files are difficult and challenging to make changes to; in fact, this is one of the format’s main advantages.

When PDF Can Be of Use

This format is perfect to share files that contain classified information or information that is protected by copyright. PDF files are challenging to edit as is, but it is also possible to set the settings so that the receiver won’t be able to make any changes or even copy the contents of your document. For example, you can’t simply take contents of two PDFs and clump them together – you’ll need a special app to merge PDF files. If you need to send a document via e-mail or store it in the online storage, then PDF should be your format of choice. This format is also a great option for a questionnaire or some other form to fill out, which you can put up on your website, as well as for printing out your digital documents.

If you don’t know what operating system the recipient has or what device they will use to open the files you send them, then it’s better to opt for PDF. By sending PDFs, you will make sure that the files will be viewed properly, and their layout and formatting will be preserved. For this reason, for instance, resumes and cover letters are usually required to be in PDF. You don’t even have to worry about whether the recipient has a special software or an app to open your files – it can be easily done with the help of the most popular browsers. Such browsers as Google Chrome, Mozilla Firefox, Microsoft Edge have built-in PDF viewers. Therefore, even if the recipient doesn’t have Adobe Acrobat Reader, it will still be possible to view the documents that you sent them. There will be no need to download or install any extra apps.

Pros and Cons of PDF

PDF files tend to contain lots of text, and some graphics (vector or raster). It’s much less common for a PDF document to include 3D graphics, bits of code (for example, JavaScript) and some other unusual elements. In other words, PDF is usually used to share files that contain a lot of text and some kind of images.
