How to Add, Edit, and Remove Watermark in PDF

Watermarks are useful for indicating ownership, branding, or document status. With PDNob PDF Editor, you can quickly insert, modify, or remove watermarks using built-in tools designed for both single files and batch operations.

1. Add Watermark for a single PDF

To place a watermark on a single PDF file, follow the steps below.

• Open your document, go to the "Edit" tab, and choose "Watermark".
  
• Choose the type of watermark you want to use: Text, Image, or PDF.
  
• Input your text or import a file, then adjust properties such as font, color, opacity, size, and watermark layout to match your needs.
  
• Adjust placement settings, including whether the watermark appears in the foreground or background, and decide if it should repeat across the page.
  
• Set the page scope where the watermark will appear, such as all pages or a selected range.
  
• Click "Save" to finalize and apply the watermark.

2. Edit Watermark in PDF

You can update an existing watermark at any time.

• Open the "Watermark" panel under the Edit tab and locate the current watermark.
  
• Click "Edit" to reopen the settings. Adjust content, style, or layout as needed, then click "Apply" to save changes.

3. Batch Add/Remove watermark in PDF

Batch processing allows you to manage watermarks across multiple PDFs efficiently.

• Open "Batch PDF Tools" from the main interface and select "Watermark".
  
• Click "Add Files" or "Add Folder" to import the PDFs you want to process.
• Choose "Add Watermark" to insert a new watermark, then configure text or file-based watermark options.
  
• Alternatively, switch to "Remove Watermark" and click "Apply" to automatically detect and remove existing watermarks.
