Invert PDF Colors
Invert any PDF's colors permanently in your browser. True RGB complement inversion - white pages become black, black text becomes white. Adjust resolution and quality, then download. No uploads, no sign-up, fully offline and private.
Images look wrong? Try turning on Preserve ImagesPreserve Images detects photos and graphics and keeps their original colors after the inversion. Turn it on to protect images from being inverted.
Not working? Try turning off Preserve ImagesScanned PDFs are made of images, not text. When Preserve Images is on, the converter keeps those images as-is, which means the page stays bright. Turning it off lets the converter invert everything.
How It Works
Upload Your PDF
Click the upload button or drag a PDF onto the page. Nothing is uploaded - the file is read locally in your browser.
Colors Are Inverted
Every pixel is mapped to its RGB complement using GPU-accelerated color matrix transforms. Pages are processed in parallel for speed.
Download
The inverted PDF downloads automatically. It includes a hidden text layer so you can still select, copy, and search text.
What Is PDF Color Inversion?
Color inversion replaces every color in a PDF with its RGB complement. White backgrounds become black, black text becomes white, and every other color shifts to its opposite on the spectrum. The result is a true photographic negative of the original document.
Unlike OS accessibility filters or browser extensions that only change what you see on screen, this tool creates a new PDF file with inverted colors baked in permanently. Share it, print it, open it on a different device - the colors stay inverted.
Why Use This Tool
Permanent Inversion
Creates a real PDF with inverted colors. Not a screen filter - the file itself is changed.
GPU-Accelerated
Uses SVG color matrix filters on your GPU and processes pages in parallel. 50 pages in seconds.
Selectable Text
The inverted PDF keeps a hidden text layer so you can search, select, and copy text.
Completely Private
Your file never leaves your device. No upload, no server, no cloud. Works offline.
Works on Scanned PDFs
Inverts at the pixel level, so it works on both text-based and image-based PDFs.
Adjustable Quality
Resolution and JPEG quality sliders let you trade file size for sharpness.
Inversion vs. Dark Mode
True color inversion flips every color to its mathematical complement. White becomes pure black, blue becomes orange, green becomes magenta. This produces a "negative" effect that also affects images and colored graphics.
Dark mode conversion is smarter: it maps white backgrounds to a specific dark tone while preserving image colors and keeping text readable. If you want a more refined reading experience, the full converter offers 16+ themed dark modes like Dracula, Nord, Solarized, and more.
Frequently Asked Questions
Inverting colors replaces every pixel with its RGB complement: white becomes black, black becomes white, blue becomes orange, and so on. The result is a true negative of the original document, useful for reducing glare or improving readability in dark environments.
Yes. Unlike browser extensions or OS accessibility filters that only change what you see on screen, this tool generates a new PDF file with inverted colors baked in. Open it on any device, any PDF reader, and the colors stay inverted.
Yes. The inverted PDF includes an invisible text layer so you can select, copy, and search text just like in the original. It works in every major PDF reader.
No. The entire conversion runs in your browser. Your file never leaves your device. You can even disconnect from the internet after the page loads.
Acrobat and extensions change how the PDF looks on your screen, but don't change the actual file. When you share it or open it elsewhere, the colors are back to normal. This tool creates a new PDF with the inverted colors saved permanently.
Yes. The converter treats each page as an image and inverts at the pixel level, so it works on both text-based and scanned/image-based PDFs.
Yes. The full converter includes 16+ themes like Dracula, Nord, Solarized, and Monokai. Just switch the theme in the dropdown.
Yes. The interface adapts to any screen size and works in Chrome, Safari, Firefox, and Edge on both Android and iOS. No app install required.
