uMark enables you to add a text or image watermark to your digital photos. You can fully customize the placement of your watermark, set a custom font , size and color, as well as opacity level. You can insert special characters like �© and �® and also rotate the watermark. uMark can process images of type jpg, gif, bmp and png. You can rename the resulting images and even cerate thumbnails. uMark gives you an option to convert your images and produces high quality images. The watermarked images are saved in a new folder, so your originals remain unchanged.
