Online TTF to EOT Font Converter

August 5, 2009 by Noah
After posting my initial blog post about embedding fonts in a way that works with Internet Explorer and Firefox 3.5, a reader has informed me that he had some trouble running the ttf2eot program on Windows XP.

So I've created a web-based converter tool to turn TrueType TTF fonts into OpenType EOT fonts, to go along with my other tools that turn images into favicons and turn images into XBM masks.

You can use the new tool here. As with all the other tools, your converted files are cleared off the server after 24 hours, so don't think about hotlinking your embeddable fonts!

I just tried converting a font, Cooper Std, with firefox and it works... but in Internet Explorer it just outputs a standard looking font. Any ideas?

This would be the best tool if it actually worked. Run it in IE and you'll see what I mean. It just defaults to Verdana.

For me, it actually did not worked. I got this: "The conversion has failed! Maybe your uploaded TTF file isn't valid?"

The "conversion has failed" error is shown when the ttf2eot binary exits with an error code and the resulting EOT file is 0 bytes long. You'll see it if you upload a TTF that is also 0 bytes long (an empty file), but a corrupt TTF file would also cause that error too.

If you're absolutely sure the TTF is valid (i.e. you can open it with your local font viewer), it may just be in an unusual format and the ttf2eot binary can't convert it. In which case, download and run ttf2eot yourself ( - if it doesn't work there either, bug the creator of ttf2eot. :)

I'm from Brazil and I am very grateful for it! I managed to change the properties of the stylesheet.css file and convert the font CALIBRI.ttf to .eot on your site! I managed to actually change any source of my site! Grateful ...

Hello, as RussianGril mentioned it doesnt work for cyrillic fonts. The only change that appears are the letters but those are not much different from the latin numbers.
