Change Background Color - Free Online Browser Tool

How to Use the Change Background Color Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the PDF

    Drop in the document you want to tint.

  2. Choose a colour

    Pick from the preset palette or enter a custom colour. Pale, low-saturation tints read best behind body text.

  3. Apply to the page background

    The tint is drawn beneath existing content, not over it, so nothing becomes harder to read.

  4. Download

    Save the tinted document. Your original stays white.

Frequently Asked Questions

Will a coloured background make my text harder to read?

If you choose a pale, low-saturation tint, no — contrast stays comfortably high. Avoid dark or saturated backgrounds behind body text.

Does it affect printing?

Considerably. A full-page tint is printed across the entire sheet, which uses far more toner than white and is a poor choice for drafts.

Is the background a real fill or just drawn content?

A real fill drawn beneath the page content, so it behaves like paper colour and does not obscure anything.

Can I use it on only some pages?

Yes. Select the pages to tint, which is useful for alternating sections or marking a draft section within a final document.

Does this change the page size?

No. It is a colour change only; all page dimensions are untouched.
