Overlay two PDFs

Vellum applies a second PDF document onto every page of the first, above or below depending on your choice, to reproduce the effect of pre-printed letterhead, a page background or a decorative frame. The operation covers every page of the main document in one pass. Both files are processed in your browser, with nothing sent to a server.

How do you overlay a letterhead onto every page of a PDF?

Upload the main document and the PDF containing the letterhead or background, choose whether it goes above or below each page, and confirm: the overlay is applied to every page of the main document in one pass.

Can I use a decorative background instead of a letterhead?

Yes, the second PDF can be any template: a page background, a decorative frame or pre-printed letterhead — the tool reproduces the same visual effect on every page.

Are both files uploaded to a server, and does the tool cost anything?

No, both PDFs are processed entirely in your browser, with nothing sent to a server, and the tool is free.
