PDF Full Form – Full Form Of PDF, I Love PDF, About PDF, History, Founder.
In this article I will share PDF Full Form, So Full Form Of PDF is Portable Document Format , PDF was standardized as ISO 32000 in 2008 and therefore no longer requires royalties for its implementation.
What PDF Means / What Is PDF / Meaning Of PDF / PDF Meaning ?
Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1993 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it.

About PDF
A PDF file contains 7-bit ASCII characters, except for certain elements that may have binary content. The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7. The format is a subset of a COS (COS Full Form – “Carousel” Object Structure) format.[18] A COS tree file consists primarily of objects, of which there are eight types:[19]
Boolean values, representing true or false
Numbers
Strings, enclosed within parentheses ((…)). Strings may contain 8-bit characters.
Names, starting with a forward slash (/)
Arrays, ordered collections of objects enclosed within square brackets ([…])
Dictionaries, collections of objects indexed by names enclosed within double angle brackets (<<…>>)
Streams, usually containing large amounts of optionally compressed binary data, preceded by a dictionary and enclosed between the stream and endstream keywords.
The null object
Furthermore, there may be comments, introduced with the percent sign (%). Comments may contain 8-bit characters.
Objects may be either direct (embedded in another object) or indirect. Indirect objects are numbered with an object number and a generation number and defined between the obj and endobj keywords if residing in the document root. Beginning with PDF version 1.5, indirect objects (except other streams) may also be located in special streams known as object streams. This technique enables non-stream objects to have standard stream filters applied to them, reduces the size of files that have large numbers of small indirect objects and is especially useful for Tagged PDF. Object streams do not support specifying an object’s generation number (other than 0).
An index table, also called the cross-reference table, is typically located near the end of the file and gives the byte offset of each indirect object from the start of the file.[20] This design allows for efficient random access to the objects in the file, and also allows for small changes to be made without rewriting the entire file (incremental update). Before PDF version 1.5, the table would always be in a special ASCII format, be marked with the xref keyword, and follow the main body composed of indirect objects. Version 1.5 introduced optional cross-reference streams, which have the form of a standard stream object, possibly with filters applied. Such a stream may be used instead of the ASCII cross-reference table and contains the offsets and other information in binary format. The format is flexible in that it allows for integer width specification (using the /W array), so that for example, a document not exceeding 64 KiB in size may dedicate only 2 bytes for object offsets.
Brief History Of PDF / PDF History
Adobe Systems made the PDF specification available free of charge in 1993. In the early years PDF was popular mainly in desktop publishing workflows, and competed with a variety of formats such as DjVu, Envoy, Common Ground Digital Paper, Farallon Replica and even Adobe’s own PostScript format.

Little has changed from that point forward, other than the expansion of Catalan, French, and English until July 2011 when the Premium rendition was added[4], which multiplied the record size and assignments accessible, eliminated advertisements, and furthermore interestingly a client board was made alongside a got association (https://) at a cost of €3.99 each month.
On the eighteenth of April 2014 the transformation apparatus was carried out, which permitted to change over Images (JPG, PNG, TIFF, BMP, EPS, GIF, ICO, PSD), records (DOC, TXT, RTF, ODT, PDF), and sound (MP3, M4A, WAV, AIFF, OGG) and before the current year’s over a digital book Converter just as availability for Chinese was additionally added.
