What is Add Background?
Add Background applies a solid color fill behind the content of every page in a PDF. It uses pdf-lib to draw a full-page rectangle in the specified color, effectively changing the page background from white to your chosen shade.
How to Use Add Background
- Upload your PDF file.
- Enter a hex color code for the background (default is
#f5f5f5, a light gray). - Click Add Background. A filled rectangle is drawn on every page behind the existing content.
- Download the result as
background-added.pdf.
Why Use Add Background?
A background color can improve readability, match brand guidelines, or add visual contrast. This is especially useful for PDFs with transparent elements or documents that will be presented on-screen where a colored background looks more polished than plain white.
Privacy & Security
Your files never leave your browser. The background addition happens entirely on your device. Nothing is uploaded to Racira's servers, no copies are stored in the cloud, and no file data is transmitted at any point.
Frequently Asked Questions
Will the background cover my content?
The background rectangle is drawn before the existing page content, so your text and images remain visible on top. If you use a very dark color, it may reduce contrast with dark text.
