Invert Colors

Inverting PDF colors creates a dark-mode version of a document — white backgrounds become black, dark text becomes light. This is useful for reading in low-light environments, reducing eye strain, and creating high-contrast versions for accessibility. The inversion is applied to all page content: images, backgrounds, and graphics are all inverted. Text that appears as dark-on-white becomes light-on-dark. Use cases: creating a dark-mode version of a technical document for night reading, generating a high-contrast version for accessibility, producing a visual inversion for a design effect, or creating a print-friendly negative version of a photo-heavy document.
