WWF is a modification of the open standard PDF format for document exchange endorsed by the World Wide Fund for Nature (also abbreviated WWF) Germany. [1] The WWF format is promoted as being more environmentally friendly than other comparable document exchange formats (e.g. PDF or DOC) since documents in this format are designed to be more difficult to print. The motivation behind the use of the format is to prevent unnecessary printing of documents. The website claims that the file format will be able to be read by most programs that can open ordinary PDF files. [2] At present, the software for creating WWF files is available for Mac OS X 10.4 and for Windows XP and later. [3] An open-source equivalent is available for Linux and for Windows XP and later. [4]
WWF files are simply PDF files with the security settings for printing set to "not allowed", [5] and the file extension ".wwf".
Thus, the inability to print the files comes from the DRM built into Adobe Reader, which looks at a flag in the PDF to see whether printing is allowed. [6] Other PDF readers, such as Ghostscript, may not honour the no-print flag, rendering WWF files printable. [5]
The initiative has been criticised [5] [7] [8] for restricting users rights, being ineffective (as non-Adobe readers such as Ghostscript can print documents in the format), for violating the BSD license, [9] for being incompatible with the goals of the free and open source software movement and for the software contacting the WWF without the user's consent. [10] It was criticised by WWF International director of corporate relations Maria Boulos for being "misleading" and having been launched as "a global product" despite being created by the WWF's German division without consultation with WWF International.

Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 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. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020.
Adobe Photoshop is a raster graphics editor developed and published by Adobe for Windows and macOS. It was originally created in 1987 by Thomas and John Knoll. Since then, the software has become the most used tool for professional digital art, especially in raster graphics editing. Owing to its fame, the program's name has become genericised as a verb although Adobe disapproves of such use.
Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages.

PDFCreator is an application for converting documents into Portable Document Format (PDF) format on Microsoft Windows operating systems. It works by creating a virtual printer that prints to PDF files, and thereby allows practically any application to create PDF files by choosing to print from within the application and then printing to the PDFCreator printer.
A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program. Some programs are more suitable for artistic work while others are better for technical drawings. Another important factor is the application's support of various vector and bitmap image formats for import and export.
Open XML Paper Specification is an open specification for a page description language and a fixed-document format. Microsoft developed it as the XML Paper Specification (XPS). In June 2009, Ecma International adopted it as international standard ECMA-388.
PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents. PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking and encryption. The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations.
