Common Document Format Found on the Internet

Document formats are the files that store the formatted content of a document. A file format is a standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary or free and may be either unpublished or open.

Let’s have a look at some common document formats that you’ll find on the internet.

Some of The Common Document Formats on the Internet

Though there are hundreds of different types of document formats in use today, there are a handful that are used more often than others. Here’s a look at some of the most common document formats found on the internet.


PDF, or Portable Document Format, is one of the most common document formats on the internet. PDFs are versatile and can be easily viewed on a variety of devices.

In addition, PDFs can be password-protected and encrypted, making them ideal for sharing sensitive information. However, PDFs are also notoriously difficult to edit, and they often don’t format well for printing.

As a result, they are not always the best choice for creating final versions of documents. Nonetheless, PDFs remain a popular format for sharing information online.


The DOCX format is another commonly used file format introduced by Microsoft. DOCX files are based on the XML standard, and they use the .docx file extension. Unlike the older DOC format, which uses a proprietary binary format, DOCX files are much smaller and easier to work with.

In addition, DOCX files are fully compatible with all versions of Microsoft Word, making them ideal for sharing documents between different users.


The PPTX format is a file format that is commonly used for presentations. It is a file format that is based on the XML standard and uses a ZIP compression algorithm.

The PPTX format was first introduced in 2007 by Microsoft and it is the successor to the PPT format. The PPTX format is now the default file format for Microsoft PowerPoint.

The main advantage of the PPTX format over the PPT format is that it uses lossless compression, which means that no information is lost when the file is compressed. The PPTX format also supports transparency and it can be password protected.


XLSX is another most commonly used document format that is used for excel files and was introduced by Microsoft. The XLSX format is based on the XML format and uses ZIP compression to reduce file size.

It is also designed to be more robust than the older XLS format and can handle larger files with more data. One of the benefits of the XLSX format is that it can be opened by many different programs, including Microsoft Excel, Apache OpenOffice, and Google Sheets. Another benefit is that it is easy to convert XLSX files to other formats, such as PDF or CSV.


Last but not the least; TXT is the most basic document format that is used for storing text. TXT files are simple text documents that can be created using any text editor.

They are often used for storing raw data or for plain text documents such as README files. TXT files are also a popular format for documents that are meant to be read by humans, such as eBooks or articles.

One advantage of TXT files is that they are very lightweight and easy to open. However, they are not well suited for storing complex data or formatting.

Which One is the Most Widely used

There is no single most popular document format on the internet. Each of the formats listed above has its own specific use and purpose. However, if we look into the general usage, then PDF is the most widely used format for documents.

This is because PDFs are versatile, can be easily viewed on a variety of devices, and can be password-protected and encrypted.

How to save a document as a PDF file

To save a document as a PDF file, you can simply follow the below-given steps and you’ll be done in no time.

  1. Open the document you want to convert to a PDF.
  2. Click File > Save As.
  3. In the “Save As” dialog box, select PDF from the “Save as type” drop-down menu.
  4. Enter a name for your file and click Save. That’s it! You’ve now saved your document as a PDF.

One thing to keep in mind is that not all documents are well suited for conversion to PDFs. For example, if you have a document with lots of images or complex formatting, it might not look quite right when saved as a PDF.

In those cases, it’s best to stick with the original file format. But for most purposes, converting to PDF is a quick and easy way to ensure that your document will look just the way you want it to – no matter where it’s viewed.

How to create a PDF file

There are a few different ways to go about creating a PDF file, but the easiest is to use a program like Adobe Acrobat. Acrobat will let you convert just about any type of file into a PDF – and it’s really easy to use.

Just open up the document you want to convert, click on File > Export To > PDF, and voila! You’ve just created your very own PDF file.

If you don’t have access to Acrobat (or if you’re just feeling thrifty), there are also a number of free online PDF converters that will do the job just as well.

Just head on over to Google and search for “PDF converter,” and you’ll find plenty of options to choose from. So go ahead and give it a try – creating PDF files is easier than you might think!

The Bottom Line

So there you have it! The most common document formats are found on the Internet. While this is not an exhaustive list, it should give you a good starting point for understanding the types of files that are commonly used online, and you may now be able to understand what makes the PDF on top of all.
