Difference between PDF and HTML
PDF vs HTML:
A computer file is a block of arbitrary information or a device for storing information, which is available to a computer program and is usually based on some kind of durable storage. There are different file types, which are used for different purposes. When such a file is saved on the computer, they use some extensions such as .txt, .doc, .pdf, .html at the end of the file name. This extension describes the format of the particular file. Among these files, PDF and HTML files, which are the most famous file types, are the most confusing since they have many similar features. Despite these similarities, there are many distinguishable features. Therefore, this article is focussing on identifying the differences between PDF and HTML.
What is PDF?
PDF is the abbreviation for the Portable Document Format, which is a file format used to represent documents in a manner independent of application software, hardware, and operating systems. This format was originally developed by the Adobe Systems. Simply PDF files can be viewed using Adobe Acrobat reader, which is a proprietary format that allows you to read electronic documents, either on or off line. Therefore, to view a file in PDF format, you need Adobe Reader, a free application distributed by Adobe Systems. PDF uses the PostScript printer description language and is highly portable across computer platforms. PDF documents have a .pdf file extension. A PDF document may contain images and text, as well as hyperlinks. This format provides a page-by-page view of documents, exactly as they appear in their printed form, as well as allowing keyword search. PDF captures formatting information from a variety of desktop publishing applications, making it possible to send formatted documents and have them appear on the recipient’s monitor or printer as they were intended. However, as PDF is based on a variant of PostScript, each document is self-contained, packing text, graphics, and fonts into a single file. Although they contain the complete formatting of the original document, including fonts and images, PDF files are highly compressed, allowing complex information to be downloaded efficiently.
What is HTML?
HTML or Hypertext Markup Language is a computer language devised to allow website creation. Therefore, HTML is the “language” that web pages are written in, for displaying web pages and other information that can be displayed in a web browser. These websites can then be viewed by anyone else connected to the Internet. Thus, developed by scientist Tim Berners-Lee in 1990, HTML is the “hidden” code that helps us communicate with others on the World Wide Web (WWW). When writing HTML, you add “tags” to the text in order to create the structure. HTML defines the structure and layout of a Web document by using a variety of tags and attributes. These tags tell the browser how to display the text or graphics in the document. The first tag in a pair is the start tag, the second tag is the end tag (they are also called opening tags and closing tags). In between these tags web designers can add text, tags, comments and other types of text-based content. The text is then saved as an html file, and viewed through a browser. This browser reads the file and translates the text into a visible form, hopefully rendering the page as the author had intended. HTML allows images and objects to be embedded and can be used to create interactive forms.
What is the difference between HTML and PDF?
HTML and PDF are two of the most popular file formats on the Internet. They share similar functions and are both used to display information; however, they are different in many ways. Above all, HTML files are used to create websites, while PDF files are used to share documents. PDF does not change its appearance when viewed in different computers. To view a PDF file, one should have an Adobe Acrobat reader and to view a HTML file, one should have a web browser. Once the html file is released to the World Wide Web, it can be viewed by anyone, using the internet, if they have a browser and internet facility. To view a PDF file, internet facility is not necessary. One can view the PDF file online or offline as well. Internet can be used to send and receive PDF files. Both HTML and PDF files contain formatted text, images tables and hyperlinks as well.
HTML is basically a language, which is used to write web pages, while PDF is a compressed file type. HTML documents can be written by anyone with a text editor and knowledge of the language. PDF documents, in contrast, can be created by importing files into Adobe Acrobat and converting them. Some applications contain a PDF plug-in that allows you to save your files as a basic PDF but does not provide you with the advanced features of Adobe Acrobat. When it comes to the file safety, PDF files top since PDF can be password protected to prevent unwanted editing and printing. They can contain digital signatures that help verify the sender of the file. When it comes to HTML files, they can be viewed by anyone using the internet and most often, anyone can view the source file of the website through the ‘view source’ option on most of the web browsers.
The appearance of these two file types is different. A web site or the last result of a HTML file has no page numbers or any other formatting, which we find in PDF in relation to the print layout. Unlike the website, PDF is seen as the actual printout of the document. Thus PDF files are great for manuals and e-books. Thus, PDF files print just as the author intended to, while HTML files do not always do so. There is a set of standards, which are used in terms of HTML files and PDF files. The HTML standard is maintained by the World Wide Web Consortium, which helps ensure that hypertext markup language is freely available and readable on all computers. The PDF was a proprietary standard created by Adobe Systems, but in 2008 was released as an open standard. The International Standards Organization currently publishes the PDF standard. When a PDF file is created, all the images and text are embedded to it, while the HTML file preserves the source of its images in a separate folder.
