Add your document first and the overlay PDF second.
Download the Letter source and its A4 version. Use the source as base and its A4 version as foreground. Expect two pages with the second PDF layered over the first, not four joined pages.
How to use Overlay PDF
Add the base first and foreground second
A one-page foreground repeats; otherwise page counts must match. Set opacity and check paper proportions.
Apply overlay
Keep the source, run the task and inspect the result before accepting it.
Inspect coverage of underlying text
Compare the saved copy with the practice result described above before using your own document.
Overlay one PDF on another without adding pages
Add the base PDF first and the foreground PDF second. A one-page foreground repeats on selected base pages; otherwise the files must have matching page counts.
A practical example
For a three-page report with a separate cover, use a one-page letterhead and select 2-3. The cover stays without the overlay and the output still has three pages.
What to check in the result
Opacity fades the whole foreground. White areas can cover underlying text; the tool does not turn them transparent. Use upright pages and matching proportions, then inspect the downloaded result.

Questions & answers
How is overlaying different from merging PDFs?
Merging appends pages. An overlay places a foreground PDF on the same base pages, without adding its pages to the document.
Why does my letterhead cover the document text?
The overlay is a foreground layer. Opaque white areas can cover the base text. Opacity fades the whole overlay; it does not automatically remove its background.
Can I repeat one overlay on every base page?
Yes. A one-page overlay repeats across the selected base pages. Otherwise the two PDFs must have matching page counts.
