Frequently Asked Questions

When using PDF Background Color, what does this tool do?

Adds a colored background layer to every page in a PDF. Choose any color and the tool inserts a full-page colored rectangle behind the existing content.

Does it cover the text?

No. The background color is placed behind the existing content. Text and images remain visible on top of the colored background.

Can I apply different colors to different pages?

The basic tool applies one color to all pages. For per-page colors, process pages individually or use a PDF editor.

What file size impact does adding color have?

Minimal. The color layer adds very little data. File size may increase by 1-5% depending on page count.

Is my PDF data stored?

No. All processing happens locally in your browser using pdf-lib. No PDF data is uploaded to any server.
