このツールについて
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.

よくある質問
What is the difference between Overlay and Underlay?
Overlay places the secondary layer on top of your main content. Underlay places it at the very bottom, acting as a background template.
Can I loop the overlay layer?
Yes, if the layer PDF is shorter than the base document, enabling Loop will cycle it (e.g. page 1, 2, 1, 2) to cover all base pages.
Is page range supported?
Yes, you can target specific pages using range syntax such as "1-5", "odd", "even", or comma-separated lists.
