PDF Overlay
Base + overlay blended live at your chosen opacity — letterheads and stamps, previewed before export.
A little guidance. A better result.
How to use PDF Overlay
Blend base and overlay live at your chosen opacity before exporting.
Prepare your input
Choose a base PDF and an overlay PDF.
Use the workspace
Set the blend opacity and inspect the combined preview.
Check your result
Export and check alignment, especially when the source page sizes differ.
Know the limits
Overlaying combines visible content; it does not compare changes or remove content from the base.
