Sometimes happens, you are working in your art and you want to submit it into this site. But you don't have the apps to convert your images into BLP format. No more worries: Wc3Borderizer Online is your web tool to create nice borderized icons that really fits in Warcraft III maps. Just upload the image file and it will generate the icons in all the styles used in WC3.
