How does the Set Page Background Color work?

Set the background colour of every page. Useful for: cream-paper look on novel drafts (#fff8dc), dark-mode reading PDFs (#1f1f1f), themed prints (brand colour). Content sits ON TOP of the colour rectangle so text and images keep their original rendering. Runs in your browser — works on any non-encrypted PDF.

🔒 Security & Privacy

All processing happens on your device. Your files never leave your browser, never touch our servers, and are not stored anywhere. Close the tab and the file is gone.

📱 Use it on any device

Works in any modern browser — Mac, Windows, Linux, iPhone, Android, and tablets. No installation, no app to download. Just open the page and start.

⚡ Quick & easy

Drag, drop, click. Most files process in seconds, not minutes. No watermarks added to your output, no per-day limits, and the tool always shows the result before asking you to download.

🎁 Always free, no signup

Free to use, every time. No account creation, no email required, no “trial” that converts to a paid plan. We make money from ads so you don’t have to pay.

Frequently asked

Maybe not — this tool doesn't invert text colours, only adds a background. For dark mode, run text through a colour-invert step first.
