The Portable Document Format (abbreviated PDF), is a file format based on a page description language developed by Adobe Systems in 1993 to represent documents independently of the hardware and software used and, in 2007, it became a standard international certified.
To be able to view a PDF file, you simply need to have or download the Adobe Reader program (a free software for viewing and printing developed for the main hardware platforms and operating systems).
On the Web, smaller files are preferable, because the duration of a download depends on the size of a file; PDF files can be optimized to reduce their size and create files up to 80% smaller than an equivalent HTML file.
Authors of PDF files can prevent users from editing, printing and / or copying the content (text and graphics).
A PDF file contains (or can be set to contain) all the components needed to view the file. No need to worry about separate files for images, fonts, etc.
The PDF format was designed to keep its appearance identical on any computer platform. Thus the problems of formatting documents created by the graphic designer on a PC and then processed on a Mac don’t apply.
Typically, a PDF file is considerably smaller than the same document in another file format. The elements of the file are compressed and according to the type of element, the images can be resampled to the most suitable resolution.
To create a PDF file, you only need your graphics software or a component of Adobe Acrobat (available for purchase at low cost).
The basic architecture of a PDF file has been carefully studied. The shape and attributes of each element are recorded in the file, including text, fonts, colors, graphics, and raster images. Shapes and attributes are individually accessible and can be edited, without touching any other aspect of the file. You can then make last-minute changes to the file using editing tools.
Adobe developed the PDF format as a document exchange format between computers of different platforms. With the advent of the Internet it has become the preferred format for publishing documents where it was important to keep the graphic formatting intact. The graphic community also adopts this format for the sharing of printwork.
There are some essential requirements involved with these different types of uses: color used, image resolution, the ability to annotate the document, printing specifications (overprint, page definition box), protection, and so on.
The PDF specifications have therefore evolved over time to encompass these elements.
Our program gives you the possibility to create this type of format and then choose whether to use it for printing or publishing data on the web.
