Overlay PDF
Runs locally in your browser. Nothing leaves your device.Place letterhead, logos, or other PDF layers in front of or behind PDF pages.
How it works
- 1
Select base and layer PDFs
Select one or more base PDFs and exactly one layer PDF.
- 2
Set the position and page mapping
Choose foreground or background and the appropriate page-mapping mode.
- 3
Review and download the result
Check the preview and download the combined PDF directly, or multiple results as a ZIP.
Good to know
The overlay tool structurally combines each base PDF with a single layer PDF directly in your browser — as a foreground over the content or as a background behind it. Several page-mapping modes are available: first page on all, sequential, sequential with the last page repeated, cyclic repeat, even/odd only, and a custom range.
Pages are combined structurally without rasterizing; the layer PDF is not automatically scaled or repositioned, so page size and the preview should be checked beforehand. Multiple base PDFs can be combined with the same layer in a batch; results are bundled as a ZIP.
Typical use cases
Apply letterhead or a logo across multiple documents
Select multiple base PDFs and a layer PDF with letterhead or a logo as the background to brand them consistently in one pass.
Place a watermark only on specific pages
Use the page mapping to show a watermark only on even or odd pages, or in a custom range, as a foreground.
Tips for better results
Check page size and the preview beforehand
The layer PDF is not automatically scaled or repositioned — if its format differs from the base document, content can appear shifted.
Choose the right repeat mode
Use cyclic repeat for multi-page layers such as alternating headers and footers, or “first page on all” for a uniform watermark.
Features
Six page-mapping modes
First page on all, sequential, with repeat, cyclic, even/odd, or a custom range.
Foreground or background position
Place the layer PDF either in front of or behind the base file's content.
Local, structural combination
Pages are combined structurally without rasterizing, entirely locally in the browser.
Frequently asked questions
Is the layer PDF automatically adapted to the base file?
No. The layer PDF is not automatically scaled or repositioned — check the page size and preview before exporting.
Can I process multiple base PDFs at once?
Yes. Each selected base PDF is combined with the same layer PDF; results are bundled as a ZIP.
