About changing a PDF's background color

Tinting a document's background — a soft cream instead of stark white, a pale color to match a brand — is a small visual change that's normally impossible without opening the file in a design tool and rebuilding each page. This tool tints every page's background to a color you pick directly.

It re-renders each page as an image with pdf.js, replaces the light background pixels with your chosen color while leaving darker content (text, graphics) intact, and rebuilds the PDF with pdf-lib — entirely in your browser. Because it works by re-rendering, selectable text on the original page becomes part of a flattened image afterward.

Supported files

Accepts a PDF and a color. Produces the same PDF with every page's background tinted to that color.

Is my file uploaded?

No. The whole process runs in your browser with pdf.js and pdf-lib — nothing is uploaded.

Change PDF Background Color — frequently asked questions

Does the text stay readable?+

Yes — dark content is multiplied over the new background so it stays visible. Pick a light colour for best results.

Is it reversible?+

No — pages become flat images. Keep your original.

Is there a free way to change a PDF's background colour?+

Yes — this tool tints the background entirely in your browser, free and with nothing uploaded.

Can I preview the new colour before applying it?+

Yes — a live preview on the current page shows the tinted background before you apply it to the whole document.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
