Here is the reference code for making WOFF files: http://people.mozilla.org/~jkew/woff/ I have a mirror: https://github.com/samboy/WOFF
To compile and install, make sure you have the zlib development libraries installed (e.g. in CentOS6 yum -y install zlib-devel as root), then
git clone https://github.com/samboy/WOFF
cd WOFF
make
Then, as root:
cp sfnt2woff /usr/local/bin
Once this is done, to make a webfont, enter the directory with the .ttf file, then run sfnt2woff
sfnt2woff Chortle2014f.ttf
This creates a Chortle2014f.woff webfont file. Replace “Chortle2014f.ttf” with the name of the actual webfont to convert.
The first link I provide has Windows and MacOS binaries for people who do not wish to install a compiler.
Here is the reference code for making WOFF2 files: https://github.com/google/woff2 Note that this code will not install in CentOS6, but compiles and installs just fine in CentOS7:
git clone --recursive https://github.com/google/woff2.git
cd woff2
make clean all
woff2 font generation is similar:
woff2_compress Chortle2014f.ttf
