How it works
- Choose the main document and the overlay PDF (e.g. letterhead).
- Choose position (over or under), which overlay pages to use and how to fit them.
- Click “Overlay PDFs” and download the result.
Notes and limitations
- “First page on every page” repeats the first overlay page; “Alternate” cycles through the overlay pages; “Page by page” uses overlay page 1 for page 1 and so on.
- With “Under the content”, the overlay is only visible if the main document does not paint its own white background.
- Text and graphics of both files remain sharp.
Frequently asked questions
My letterhead is not visible – why?
The main document probably has a white page background that covers it. Choose “Over the content” or use a document without a filled background.
