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.
The .gif filename extension refers to the GIF graphical file format created by CompuServe in 1987. The format is from the class of raster graphics which uses a dot matrix type data structure of orthogonally placed pixels, each with their own color information. The file format has a rich history of usage in storing sprite data for video games especially those released in the early 90's. The GIF format has also been used in low-resolution animation clips distributed over the internet, and in design of sharp-edged art that utilize a palette of a few colors up to a max of 256 colors. The GIF file format has its advantage in its compression technique, which limits file size but does not compromise image quality. The file format natively opens on many of the popular web browsers.

The .pdf file format version 1.7 was standardized in 2008 in ISO 32000-1 and is currently recognized as an open format. The most recent release is 1.7 Adobe extension level 8 supporting Adobe's proprietary XML Forms Architecture 3.3 which introduced bulleted lists, XML Encryption, and Flash integration among other features.
The GIF format is formally specified in the GIF89a Specification released in 1989 and maintained by the World Wide Web consortium. The format uses the Lempel-Ziv-Welch data compression algorithm to create a single lossless file of multiple images known as frames. The GIF file format has a structure of blocks composed of control, graphics rendering, and special purpose blocks. The blocks begin with the header block, followed by the logical screen descriptor block, the graphic control block with the actual image and or text, and finally the gif trailer marking the end of the file.
