WWF (file format)

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. 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. At present, the software for creating WWF files is available for Mac OS X 10.4 and for Windows XP and later. An Open Source equivalent is available for Linux and for Windows XP and later.

Technical details

WWF files are simply PDF files with the security settings for printing set to "not allowed", 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. Other PDF readers, such as Ghostscript, may not honour the no-print flag, rendering WWF files printable.

World Wide Fund for Nature

The World Wide Fund for Nature (WWF) is an international non-governmental organization founded on April 29, 1961, working in the field of the biodiversity conservation, and the reduction of humanity's footprint on the environment. It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States.

It is the world's largest conservation organization with over 5 million supporters worldwide, working in more than 100 countries, supporting around 1,300 conservation and environmental projects. WWF is a foundation, with 55% of funding from individuals and bequests, 19% from government sources (such as the World Bank, DFID, USAID) and 8% from corporations in 2014.

The group's mission is "to stop the degradation of the planet’s natural environment and to build a future in which humans live in harmony with nature." Currently, much of its work focuses on the conservation of three biomes that contain most of the world's biodiversity: oceans and coasts, forests, and freshwater ecosystems. Among other issues, it is also concerned with endangered species, sustainable production of commodities and climate change.
