Add a Company Letterhead or Background to a PDF

Last updated: February 24, 2026

You have a plain PDF document — a report, a letter, a proposal — and need to add your company's branded letterhead behind every page. Instead of recreating the document from scratch, PDF overlay lets you place a letterhead template behind the existing content in seconds.

The Problem

Your document was created without the company letterhead template, or you received a plain PDF that needs branding before sending to a client. You only have the PDF, not the original source file, so you can't just change the template in Word.

How It Works

1

Prepare your letterhead PDF

Create a single-page PDF of your letterhead design — logo, company address, borders, footer, and any background elements. This becomes the overlay template.

2

Open the PDF Overlay tool

Go to OneClickPDF's PDF Overlay tool.

3

Upload both files

Upload your content document as the base and your letterhead as the overlay. Select 'Background' mode so the letterhead appears behind the content.

4

Apply to all pages

Choose 'All pages' to add the letterhead to every page, or 'First page only' if only page 1 should be branded. Download the branded document.

PDF Overlay

Stamp one PDF on top of another as a background or foreground.

Frequently Asked Questions

Will the letterhead appear behind my text?
Yes. Background mode places the overlay behind the existing content, so your text and images appear on top of the letterhead design.
Can I use different letterheads for page 1 and subsequent pages?
Create a 2-page overlay PDF: page 1 with your full letterhead and page 2 with a simplified version. The tool cycles through overlay pages automatically.
What format should my letterhead be?
It must be a PDF file. If you have the letterhead as an image, convert it to PDF first using our Image to PDF tool.
Will this increase the file size?
Slightly, since the letterhead content is added to every page. If the result is too large, use the Compress tool afterward.

Brand any PDF with your company letterhead in seconds — no need to access the original source document. The overlay approach works with any PDF regardless of how it was created.
