Overview

The PDF Stationery Underlay tool allows you to professionally merge your documents with custom background templates, such as corporate letterheads or official forms. By placing your source PDF pages on top of a stationery template, you can ensure consistent branding and layout across all your exported files.

When to Use

  • •Applying a corporate letterhead to plain text documents.
  • •Adding official red-header templates to internal reports.
  • •Aligning document content onto pre-designed form backgrounds.

How It Works

  • •Upload your primary document PDF and the stationery template PDF.
  • •Select a template mapping mode to determine how background pages align with your document.
  • •Adjust the scale mode, page margins, and content opacity to achieve the desired visual result.
  • •Process the file to generate a new PDF with the stationery applied as a background layer.

Use Cases

Standardizing business correspondence with branded letterhead.
Converting plain exports into official-looking documents.
Batch-applying background watermarks or frames to existing PDFs.

Examples

1. Apply Letterhead Underlay

Background

How to Use
Upload the document and the form template, set the scale mode to 'cover', and reduce the opacity.
Example Config
templateMode: cycle, scaleMode: cover, marginMm: 2, contentOpacity: 0.85
