When Font Squirrel refuses to convert your font to a web font because of copyright issues, your online alternative is to do try a combination of other websites that provide similar services.
First, the CSS should look something like this:
src: url('yourfont-webfont.eot?#iefix') format('embedded-opentype'),
Now that you know the formats you need, let's see where you can convert your font:
Free Online Font Converter converts from pfa, pfb, pt3, sfd, ttf, otf, otb, t42, cef, cff, gsf, ttc, svg, ik, mf, dfont, bin, suit, bdf to ttf, otf, svg, pfa, pfb, bin, mm.pfa, mm.pfb, pt3, ps, t42, cid.t42, cid, cff, cid.cff, sym.ttf, ttf.bin, dfont, otf.dfont.
OrionEvent Converter converts from otf, ttf, ttc to woff and from woff to otf, ttf, ttc.
TTF to EOT Font Converter converts from ttf to eot.
That should do it for most of you. I usually go for Font Squirrel first, it's and all-in-one converter that does its job pretty well. When the squirrel rejects my font based on copyright issues, I turn to the other three online converters.
