If you have ever encountered with a file called *.wwf and doesn’t know the way to open such files then you don’t need to worry.  This is a extension of PDF format for those files which you want that shouldn’t be printed.

The WWF file extension publicized as a green file format is formed to restrict printing thus saving paper – a better way to save trees.

To open any file with an wwf extension there is not any special software required but can be opened with any application able to open PDF files.

As you have learned the use and purpose of WWF extension but I am sure now you would also like to know how you can create them and restrict any pdf file from priting. You just need to install the WWF format in your system to be able to save pdf files as .wwf files. The tool is free and simple to use which can be downloaded from the link below.
