A desktop font is designed to be installed on your computer for use with applications such as Microsoft Word or Adobe Photoshop. Desktop fonts often have special OpenType features that give the user flexibility in designing with them.
A webfont is a specially tuned font for use on websites using the CSS @font-face declaration. This will allow the text on your site to appear in the font without the font installed on your user's computers.
The Fontspring web fonts have no OpenType features and often have extraneous glyphs removed. A modern web font comes in two formats: WOFF and WOFF2. These files target 99% of browsers currently browsing the internet and can't be installed for desktop use. The remaining unsupported browsers are older and no longer supported by their developers.
If you want to create custom webfont files that include OpenType features or more languages in them. Then, you can use our Webfont Generator to make them. It can get complicated, so you can read more about the settings and what they do here.
