You have the ability to add text or an image to every picture you convert. This can be helpful if you want to make sure others do not "borrow" your images without giving recognition to where they came from.
On Step 3 of the conversion process, you will be presented with the following options:
Use Text Watermark: Add your watermark as text.
Use Image Watermark: Add your watermark as an image.
Selecting either of these options opens the Watermark Properties window. This allows you to enter text and select a font for a text watermark, and/or to select an image for an image watermark. You can also choose the position of the watermark from the drop-down menus provided and preview your watermark. Once you have adjusted your watermark to your liking, click OK.
