Change Font Family, Rename Font

How can I change a font's Family? I have 4 fonts belonging to the same family and I wish to separate them.

Also, I would also want to rename the Font itself.

A simple file name change is NOT enough.

I'm looking for a free tool to do this, but came out empty handed after Googling a bit. All Font "studios" demand money.

I should specify that I need to do this in the Operating System itself, so I need to modify the TTF/OTF/actual font file.

Solution 1:

Any special reason for changing the font details? (just curious...)

anyway i found this little tool: http://fontforge.org/ (Which is cross platform and open source!)

hope it helps :)

Solution 2:

TTFedit did the job for me. It has a much smaller footprint and was easier to use for me.

Just start ttfedit.jar, open a .ttf, select the "name" tab on the left side, edit the family names, subfamily names, etc. and save as a new .ttf.

In my case, I had to wipe Photoshop's font cache before my changed font got recognized.
