Administrators can add watermarks to all previews generated in FileCloud Server.

  • This feature requires document converter
  • Watermarks on previews is available in FileCloud Server version 17.3 and later

Example of a watermark on a document preview in the Admin and User Portals.



  • If you are not running the latest version of Document Converter, a watermark will not be added
  • To disable the use of watermarks, clear the same checkbox you use to enable them
  • Watermark settings are global
  • Watermarks can't be enabled for a specific set of files or file types, they are applied globally
  • Once watermarks are enabled, they will appear on all document previews generated in FileCloud Server

To add watermarks to previews:

 1. Install Document Converter

Administrators can use a Java-based service called FileCloud Document Converter to:

  • Enable thumbs for all Microsoft Office documents (DOC, DOCX, PPT, PPTX, XSL, XSLX)
  • Enable thumbs for Adobe documents (AI, PDF, PSD)
  • Enable thumbs for TIFF images
  • Interface with LibreOffice for document preview generation
  • Add watermarks to all previews generated in FileCloud Server

For this FileCloud uses a java program based on Apache's PDFBox.  Document converter also will use LibreOffice libraries to convert documents to PDF.

If you have not already done so, Install Document Converter.

 2. Enable watermarks

To enable the ability to combine for PDFs:

  1. Open a browser and log in to the Admin Portal.
  2. From the left navigation pane, under SETTINGS click Settings.
  3. On the Manage Settings screen, select the Misc. tab
  4. Select the Preview sub-tab.
  5. Next to Enable Document Converter, select the checkbox.
  6. Next to Watermark Previews, type in the text that you want embedded on all previews.

Now whenever user previews any document, they will see the watermark text embedded in the preview.
