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.
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
1Upload your base document This is the document that will get stamped — every one of its pages receives the overlay.
2Upload your overlay Only page 1 of this file is used, regardless of how many pages it actually has.
3Set the opacity Adjust from 10% to 100% depending on how strongly the overlay should show through.
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.
