Portable Document Format

(file format)
(PDF) The native file format for Adobe Systems' Acrobat. PDF is the file format for representing documents in a manner that is independent of the original application software, hardware, and operating system used to create those documents. A PDF file can describe documents containing any combination of text, graphics, and images in a device-independent and resolution independent format. These documents can be one page or thousands of pages, very simple or extremely complex with a rich use of fonts, graphics, colour, and images.

(Portable Document Format) The de facto standard for electronic document publishing from Adobe. Introduced in 1993, today there are billions of brochures, data sheets, white papers, forms and technical manuals on the Web in the PDF format.

Render, Save As and Edit
Adobe's free Acrobat Reader and many other applications can display and print PDF files. Various applications and conversion programs can save documents to PDF; however, editing them requires Adobe Acrobat or other software that specifically features PDF editing.

Non-Searchable Text
Most of the time, text within a PDF document can be searched as well as copied to another file. For copyright protection, PDFs can be saved as an image, which makes the text non-searchable and cumbersome to copy. However, PDF programs may offer an optical character recognition (OCR) feature that creates a text layer from the images, and that text can be searched.

Why PDFs Are Popular
Years ago, documents contained only a couple of basic fonts in order to display accurately because they relied on the installed fonts in the rendering device. However, with PDFs, document designers are free to choose whichever fonts they have at their disposal because the fonts are embedded within the PDF file itself and do not violate copyrights and patents. See PDF/X and font incompatibility.

PDF Is a Superset of Adobe PostScript
PDF is the preferred file format for sending documents to commercial print houses. If the commercial printer uses PDF imagesetters, no conversion is necessary. If it uses only PostScript hardware, the PDF files are converted to PostScript first. See PostScript, PDF/A, PDF/X, WWF, DjVu and XML Paper Specification.

PDFs Are Size Efficient
Compare the sizes of this PDF file with its JPEG and Microsoft Word (.doc and .docx) equivalents. These are all the same single-page text documents saved to four formats. Whereas the PDF and Word formats are aware of the file's contents, the JPEG image is always a matrix of pixels (see JPEG and DOC file).
