Notes: fonts are rarely embedded fully — what you typically get is a subsetted font containing only the glyphs actually used in the document. Fontmatrix saves these fonts in PFB format and stores useful information from the embedded font.
Important
The Fontmatrix team strongly discourages users from infringing copyright. This feature exists for fun and education, not for making unlicensed profit from someone else's work. If you want to create a derivative of a font whose license doesn't explicitly allow that, contact the designer or vendor first.
