Overlay PDF
Composite a letterhead, stamp, or background PDF onto or behind another PDF's pages.
About Overlay PDF
Put One PDF On Top Of Another
Some PDF jobs are really two documents: the pages you want to keep, and the thing you want printed on them. A letterhead behind a contract. A confidential stamp across a report. A background form under a scan. Overlay PDF composites a layer document with a base document so the result is one clean PDF.
Load the base document first, then load the layer PDF. Choose whether the layer prints on top as an overlay or sits behind the content as an underlay, then target exactly the pages that need it.
What You Can Control
The settings are small on purpose: placement, target pages, and what happens when the layer is shorter than the base.
Overlay Or Underlay
Draw the layer above the base pages for stamps and marks, or behind them for letterhead and backgrounds.
Page Targeting
Apply to every page, odd or even pages, ranges like 1-5, or comma lists like 2,4,8.
Loop Short Layers
Cycle a one-page letterhead across every targeted page instead of stopping after the first layer page.
Page Preview
Step through the base pages and see which layer page lands on each one before you download.
Made For Letterhead, Stamps, And Forms
Add a company letterhead behind a plain export, put a draft or confidential mark over every page, or place a form template under a filled scan. Page targeting means the cover can stay clean while the layer hits only the pages that need it.
When the layer has fewer pages than the target range, looping repeats it in order. A single-page background can cover a hundred-page document without turning the layer into a hundred-page file first.
How It Compares
Merging puts pages next to each other. Overlay puts them on the same page.

Private Compositing In The Browser
Letterhead and stamp jobs often involve contracts, HR paperwork, invoices, or scans that should not be sent to a random server. OxygenPDF reads both PDFs locally, composites them in your browser, and never uploads either file.
If a file is password-protected, unlock it inline before processing. Close the tab and the documents are gone.
