World Wide Fund has introduced a file format, called the WWF format, and has labeled it as a new green file format, with the noble idea of trying to save paper – and consequently trees!

The WWF format is a PDF that cannot be printed out. It’s a simple way to avoid unnecessary printing.

So here’s your chance to save trees and help the environment. Decide for yourself which documents don’t need printing out – then simply save them as WWF.

WWF has long worked with companies and consumers to promote responsible paper use and the option to “Save as WWF” compliments and reinforces other well-established campaigns – most notably the “Think Before You Print” initiative.

To participate in this campaign download the free software to support the WWF format, save your document/s as WWF and send it out.

Once you install it, in the Print menu of your PDF reader, you will get to see a save as WWF option.
