How to convert WOFF to TTF/OTF via command line?

Question

I know about services like Online Font Converter, but I am interested in offline solution, preferably over command line. Does anyone know a tool or workflow how to convert W

Answer 1

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

Answer 2

I wrote a simple tool for that:

Currently only tested with ttf files.
