FastStone Photo Resizer is a batch converter. You go to the directory where your files located and selected the all files that you wist to convert. Next select "Use advanced options" and the "Advanced Options" to select the necessary options including watermark selection. If you wish to rename the files, then make the changes under "Rename" option.

Click "Start" and the software will processes the files in the input list.

If you save the watermarked file in another file name that is different from the source file, you will end up with the original file without watermark and the processed file with watermark.

you keep the original file and the processed file untouched, only add watermark to a downsize version of it for web use.
