About This Tool
Overlay PDF allows you to layer pages of one PDF document on top or underneath another PDF document. It is perfect for applying letterheads, adding background grids, stamping watermarks, or fusing layout drafts together.
Supports both Overlay mode (layer goes on top) and Underlay mode (layer goes underneath). Specify custom target page ranges or loop shorter overlay documents to cover the entire base file automatically.
All processing is executed entirely inside your web browser locally, guaranteeing total security and data privacy.
