Command line utility converts TrueType and OpenType fonts to the WOFF format. It can extract from TTC collections. It is possible to revert the operation (woff to ttf) by specifying TTF as output. Accepts WOFF as both input and output to perform recompression. Compression is provided by Zopfli.

ttf2woff [-v] [-O|-S] [-t type] [-X table]... input [output]
ttf2woff -i [-v] [-O|-S] [-X table]... [-m file] [-p file] file
ttf2woff [-l] input
  -i      in place modification
  -O      optimize (default unless signed)
  -S      don't optimize
  -t fmt  output format: woff, ttf
  -u num  font number in collection (TTC), 0-based
  -m xml  metadata
  -p priv private data
  -X tag  remove table
  -l      list tables
  -v      be verbose
Use `-' to indicate standard input/output.
Skip output for dry run.

By default, ttf2woff tries to find more compact representation of some font tables (with marginal gain, usually).
