How to Overlay Two PDFs Online
PDF overlay combines two documents by placing one on top of or behind the other. This is useful for adding letterheads, stamps, watermarks, or branded backgrounds to existing documents.
Step-by-Step
- Upload content PDF — This is your main document (the base).
- Upload overlay PDF — This is the template, stamp, or background you want to combine.
- Choose mode — Overlay places the second PDF on top; Underlay places it behind.
- Select pages — Apply to all pages or a custom range.
- Combine & download — Click Combine, preview the result, then download.
Use Cases
- Letterheads — Underlay a branded letterhead template behind plain content.
- Stamps — Overlay a "CONFIDENTIAL" or "APPROVED" stamp on top of documents.
- Backgrounds — Add decorative or branded backgrounds to reports and presentations.
- Certificates — Combine a certificate template with variable content.
Privacy
Both PDFs are processed entirely in your browser using pdf-lib. Nothing is uploaded to any server. For other PDF operations, try Merge PDF or Watermark PDF.
