Add Background to PDF

Brand your documents instantly. Our Add Background to PDF tool lets you overlay any image—like a logo, letterhead, or watermark—onto the pages of your PDF file with full control over transparency and positioning.

What is a PDF Background?

A background (or watermark) is a visual layer placed behind the main text of your document. Unlike simply pasting an image, a true PDF background is applied consistently across all pages, often with reduced opacity so it doesn't interfere with readability.

How it Works

We take your uploaded image (JPG or PNG) and inject it as a new distinct layer into the PDF structure. Using standard compositing techniques, we can set this layer to be semi-transparent and position it exactly where you want, merging it seamlessly with your existing content.

How to Add an Image Background

Upload PDF: Select the document you want to style.
Select Image: Upload your logo, pattern, or letterhead file.
Customize: Use the sliders to adjust Opacity (transparency), Scale (size), and Rotation.
Download: Get your professionally branded PDF.

Powerful Customization

Transparency Control: Fade your image so text remains readable on top of it.
Perfect Scaling: Resize a small logo to cover the whole page, or keep it subtle in the center.

Frequently Asked Questions

Can I add text instead of an image?

For text-based stamps (like page numbers or simple words), check out our "Add Watermark" tool.

Will this cover my text?

The background is placed *behinds* existing content, but transparency prevents it from making text unreadable if colors clash.

Does it work on scanned PDFs?

Yes, but if your scanned page has a solid white background, it might cover up your new background image. Ideally, use clear digital PDFs.
