이 도구 정보
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.
Practical guidance before you use PDF 레이어 오버레이
Best for real document workflows
Use PDF 레이어 오버레이 when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. Corporate Letterheads is a common example: Layer invoice contents on top of standard company letterhead templates.
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you compile and download, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as merge pdf, add watermark, add page labels before repeating the task.
Start with a clean source file whenever possible. For PDF 레이어 오버레이, the first step is usually "Upload Main PDF": Drag and drop your primary base PDF document. This simple preparation step prevents most failed exports, missing pages, and formatting surprises.

자주 묻는 질문
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.
