Find my Font is a desktop application that helps you identify fonts in digital images. It opens a bitmap image and then searches online and goes through all the fonts on your computer and identifies the font(s) used by the letters in the scanned image.
You are provided with a list of matching fonts along with the matching accuracy for each one. You may also type text and see how well the matching went.
