Background Color

Change the background color of your PDF.

Guide updated August 2026

What this tool does

Background Color changes the appearance, labels, navigation, or annotations of a PDF inside the browser.

Useful for

  • Add clear visual information before sharing.
  • Standardize page labels, numbers, headers, or marks.
  • Prepare a document for review, archive, or print.

A reliable workflow

  1. Choose the source file and confirm that it opens correctly before processing.
  2. Review the available options. Start with the defaults, then change only the setting that affects your intended result.
  3. Process the file, open the result, and verify page order, text, images, links, and forms before replacing your original.

How your document is handled

Document contents are processed in your browser and are not uploaded to an AmrrkPDF application server. Your browser still downloads the application code and required runtime assets when needed.

Limits and compatibility

Some edits are added as new PDF objects rather than modifying the original text. Font substitution, transparency, rotated pages, and flattened content can affect the final appearance.

If the result is not what you expected

If an element is misplaced, verify page rotation and page size, then try a single page before applying the change to the full document.
