Invert PDF Colors
Invert every page's colors locally, useful for a dark-mode-style PDF
Invert the colors of every page in a PDF by rendering it, flipping its RGB channels, and rebuilding a new PDF. Processing happens entirely in your browser, and the result is a rasterized, image-based PDF.
No file selected.
Every page is rendered to an image and its colors are inverted, then rebuilt into a new PDF. Selectable text and vector graphics become a flat picture in the result.
Everything on this page is processed in your browser. Nothing is uploaded.
What this tool does
This tool renders each page of your PDF onto a canvas, inverts its red, green and blue channels, and rebuilds a new PDF from the resulting images, similar to a photographic negative. It is often used to make a light document easier to read in a dark room or on a dark-themed screen. Because each page is rendered as an image, selectable text and vector graphics in the result become a flat picture.
How to use it
- Choose a PDF file from your device.
- Press Invert colors.
- Download the inverted PDF.

Frequently asked questions
- Does the text stay selectable?
- No. Every page is rendered to an image before its colors are inverted, so the resulting PDF is a rasterized picture of each page rather than text and vector graphics.
- Is my PDF uploaded to invert it?
- No. Rendering and rebuilding both happen in your browser.
- Will colors other than black and white invert correctly?
- Yes. Every color channel is inverted, so a light background with dark text becomes a dark background with light text, and colored elements become their complementary shade.
