Overlay PDF — Frequently Asked Questions
What happens if the overlay has fewer pages than the base?
Choose 'First page only' to use page 1 of the overlay on every base page (common for letterheads), or 'Cycle' to round-robin through the overlay pages.
Can I put the overlay behind the base content?
Yes — switch the mode from 'over' to 'under'. Great for background watermarks that don't cover the main content.
Does this support signing?
Sort of. If your overlay is a signature page, this embeds it as a visual stamp. It's not a cryptographic digital signature — use our dedicated signing tool (coming soon) for that.
