The .pdf file format extension was developed by Adobe systems in 1993 as a means of presenting documents in a consistent manner across different platforms, hardware, operating systems, and applications. The format was not released as an open source document format until 2008, though minimal proprietary technologies still controlled by Adobe Systems exist in the format. Every .pdf document carries with it the necessary meta information required to properly reconstruct the text, fonts, and graphics used to produce the document. This ensures that documents will be viewed in exactly the same way the author intended regardless of the device used to open the document. From conception to date, Adobe Systems has continued to support the format adding features with every iteration of the standard including hardened algorithms for document encryption and privacy. Today, many freely available readers exist allowing you to open and view .pdf documents and create or convert other file formats such as .jpeg and .doc into .pdf documents.
SVG or Scalable Vector Graphic File is a graphical format for images which are bi-dimensional and XML-based providing support to animations and various interactive elements. The SVG file format was developed with the open standards created in 1999 by the W3C (Worldwide Web Consortium). Adobe Corporation held the significant role towards the development of this file format, and it is considered to be the industry standard for viewing vector graphics on web networks. SVG images can be created, edited, and recreated in any of the text editing tools and drawing or illustration software. Additionally, SVG can be compressed, searched, scripted, and indexed.
