Common Uses

Stamping a company letterhead onto a plain contract template
Applying a consistent background design across every page of a report
Branding a set of certificates with a template border or seal
Adding a standard cover design to internal documents before distribution

💡 Pro Tip

Design your overlay file at roughly the same aspect ratio as your base document — since it's centered and scaled to fit, a very differently-shaped overlay leaves more empty margin than a well-matched one.

📖PDF Overlay Guide

Stamps one PDF — like a letterhead, watermark template, or design overlay — onto every page of another PDF.

When to use this

Use this to apply a consistent letterhead or template design across an entire document without editing each page individually — especially useful when the base document was created separately from your branding.

Step-by-step workflow

  1. 1Upload your base document This is the document that will get stamped — every one of its pages receives the overlay.
  2. 2Upload your overlay Only page 1 of this file is used, regardless of how many pages it actually has.
  3. 3Set the opacity Adjust from 10% to 100% depending on how strongly the overlay should show through.
  4. 4Download the combined PDF Your file downloads as {filename}-overlaid.pdf, with the overlay scaled and centered on every page.

Tips for best results

  • The overlay is automatically scaled to fit within each base page and centered — it doesn't need to match the base document's exact size.
  • Use a lower opacity for a subtle watermark-style overlay, or full opacity for a solid letterhead.
  • If you only want a text watermark rather than a full-page design, Watermark PDF is a simpler, more direct tool for that.

Common mistakes to avoid

  • Using a multi-page overlay expecting different pages to stamp different base pages — only page 1 of the overlay is ever used, applied identically to every base page.
  • Expecting to reposition the overlay manually — it's always scaled to fit and centered, with no offset controls.
  • Choosing full opacity when the base content needs to remain clearly readable underneath a busy overlay design.
