You can convert fonts from .t1 to .TTF for free Its easy to convert a font from Mac to Windows and if you are like me where this will only happen once in a blue moon then you can download a trial version of CrossFont to get the job done. One warning is that the font will not always look the same. You can convert the font to a couple different formats including PFB+PFM(PC PS Type 1 Font), AFM (ASCII Font Metric), or OTF (OpenType CFF Font). I tried both PFB+PFM and OTF and found that for the font I was converting that PFB+PFM looked much better when used with Adobe Photoshop.
So anyhow a 15 day trial for crossfont can be downloaded here. Once downloaded then run the .exe to install the application. Start CrossFont and you will see that the interface is really easy and all you will have to do is browse to the Mac based fonts, choose what format to convert to, and click convert. Choose the C:\WINDOWS\Fonts folder to output the newly formatted font to. Now you can verify the font exists by checking to see if it is available in Microsoft Word or in Adobe Photoshop.
