Overlay PDF

Place letterhead, logos, or other PDF layers in front of or behind PDF pages.

Input

Private by design: your PDF files never leave your device.

The PDF pages are combined structurally without rasterization. The layer PDF is not automatically scaled or moved. Check page size and preview.

Overlay PDF

One new PDF is created per base PDF. Multiple results are also provided as a ZIP file.

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.

Typical searches include overlay PDF, PDF watermark, and PDF letterhead. 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.

How it works

Step by step

  1. 1

    Select base and layer PDFs

    Select one or more base PDFs and exactly one layer PDF.

  2. 2

    Set the position and page mapping

    Choose foreground or background and the appropriate page-mapping mode.

  3. 3

    Review and download the result

    Check the preview and download the combined PDF directly, or multiple results as a ZIP.

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.
