Convert TTF to WOFF

Question

I am trying to convert TTF to WOFF using various command line commands and online tools. I tried the following:

Command line:

• sfntwoff: https://people-mozilla.org/~jkew/woff/
• ttf2woff: http://wizard.ae.krakow.pl/~jb/ttf2woff/
• ruby gem: https://coderwall.com/p/kyc8lw/convert-fonts-from-the-command-line

Online:

• font squirrel: https://www.fontsquirrel.com/tools/webfont-generator
• transfonter: http://transfonter.org/

I have a ttf file of ~ 220KB in size. All of these tools generate a woff file of about 100 KB, with the exception of font-squirrel, which generates a file with ~ 20 KB optimization.

I'm curious what the font-squirrel function does, which another command line tool (read open source) cannot handle. And if possible, how can I do the same through the command line, even if it involves writing or hacking some code.

Answer 1

Simple WOFF compression should produce very similar file sizes, regardless of the tool used.

I expect Font Squirrel to do more to accommodate this additional 80K savings, such as stripping tooltips, dropping OpenType features such as small caps, or a subset to support only western languages.
