FolderMill can help you automatically add a file (image), barcode or text watermark on PDF pages and other file types. Whether you want to watermark photos, insert a watermark when printing or converting worksheets, watermark a document using time/date or some source file data, this task can be automated with this Action.
Usage examples
These are popular use cases that can be automated with this Action:
- print documents with a custom text watermark
- add a copyright notice onto images or pages (e.g., "Draft", "Confidential")
- print files with date/time stamp on the printout
- add original filename onto a specific page range
- print or convert files with the page number on every page
- place filename in the header or footer of every page
- add file's folder or subfolder path as a watermark to pages
Adding watermark in the Action Set
To enable and configure watermarking with FolderMill, add Add text or file/barcode watermark Action on the Hot Folder Settings window.
Selecting type of watermark
After creating a new Add watermark Action, select the type of watermark that you want to use by clicking the Add new watermark button. Text watermark window is opened by default, but you choose another one.

For all types of watermarks, you can set size, alignment, rotation, margins, and page range.
File watermark. Use any raster image (JPEG, PNG, TIFF, BMP, GIF), HTML, or a PDF file as a File watermark and place it in the center, top, bottom, left or right side of a document page or image.
Text watermark. For Text watermark, you can type any text and customize it using various parameters. There is also a built-in set of macros (regular expressions) that can take information from the source file and/or system time and date — use the Macro button to add them.
Barcode watermark. Using a Barcode watermark allows you to automatically add barcodes to output files. For example, you can create a QR code, adjust its size and position, and it will appear on all output images or document pages. Various barcode types are available, including Code 128, EAN, UPC, QR-CODE, and more.
Available watermark parameters
- Font, font size, and style
