Fontastic
Ever needed to quickly change size or colors of your icons? What about adding shadows or other design elements to your icons?
Let's meet Fontastic. This fantastic tool allows designers to quickly change icons to meet the unique demands of any project. You can do this by creating your own icon font. Then, upload that font to your project. Once uploaded, you can use CSS to customize the look and feel of the icons without painstakingly manipulating each icon in Photoshop:

Here's how it works. Head over to Fontastic and select icons from its huge library of over 9,000 available icon images. Next, assign letters to each of those icons (to create a font).
From there, you can modify your icons with the help of CSS. From changing color to resizing, you can do all of it through coding instead of redrawing and wasting a lot of time.
