PDF Overlay
Overlays one PDF on top of another for stamping or template-based work.
What PDF Overlay does
PDF Overlay is a free online tool that lets you place one PDF on top of another to create a single merged document. You upload two PDF files and choose whether the overlay appears as a background or foreground element, then combine them into one file. This is useful for adding watermarks, stamps, or template elements to existing documents without changing the original content. The result is a single PDF that displays both sources simultaneously within the same viewing area.

PDF Overlay FAQ
- Can I overlay more than two PDFs at once?
- The tool is designed to combine two PDF files at a time. If you need to merge multiple documents, you would need to run the overlay process sequentially or use PDF24's other merge tools.
- Are my files secure after uploading?
- PDF24 uses SSL-secured file transfer and automatically deletes all uploaded files from their servers one hour after processing. No registration is required, and files are not stored long-term.
- Do the original PDFs lose quality when overlaid?
- The overlay process merges the visual layers without re-encoding the original content, so quality is preserved. However, the final output reflects the dimensions and resolution of the files you upload.
- Can I use this tool on a mobile device?
- PDF24's tools are optimized for use across Windows, Mac, Linux, iPhone, and Android devices. The interface is designed to work directly in your browser without installing additional apps.
