Font Squirrel offers something quite unique and is something you don’t come across too often. Their website and service are designed for those who wish to convert their fonts (e.g. TTF) to webfonts. Webfonts are optimized fonts used by the webbrowsers on your computer and smartphone and are therefore wanted by webdevelopers.
Try out their font recognition software. Simply upload a screenshot or photo that contains a clear image of a text. Font Squirrel will compare the outlines of the text to their large database of fonts and show you a list of results of fonts that are very similar.
