What Invert Colors does
Invert Colors is a web-based utility that reverses color values to produce negative images, primarily designed for creating dark-mode versions of PDF documents. Users can upload a PDF file to instantly invert all colors or selectively preserve images and other elements. The processed result can be downloaded, offering a way to reduce eye strain during nighttime reading or save ink when printing drafts. The service emphasizes that all processing occurs locally within the browser, prioritizing document privacy. Beyond PDFs, the tool accepts hex color codes and RGB values, making it applicable for graphic design, web development, and photography tasks requiring color negation.
