  2. PDF4me Word Node: Configure with:
    • Operation: Add Text Watermark To Word
    • Word File Input Method: From Previous Node (Binary Data)
    • Binary Data Property Name: data
    • Watermark Text: CONFIDENTIAL
    • Orientation: Diagonal
    • Font Family: Arial
    • Font Size: 72
    • Font Color: #808080
    • Semi Transparent: true
    • Rotation: 45
    • Culture Name: en-US
    • Output File Name: word_with_watermark.docx
  3. Output: The modified Word file with watermark added

Advanced Example: Process Multiple Files

  1. Loop Node: Iterate over multiple files
  2. PDF4me Word Node: Add watermarks to each file
  3. Save/Send: Save the processed files or send them via email

Action Details

Below are concise configuration notes for each action. In n8n, set the operation in Pdf4me Word and fill the highlighted fields. Binary I/O defaults to property name data unless you customize it.
