Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

The Elixuvo PDF Color Inverter renders document pages at high resolution (150 DPI) in memory, applies color inversion and custom tone lookup tables (converting bright white backgrounds to deep black or dark slate, and dark text into crisp readable white), and reconstructs an optimized PDF.
OLED Deep Black maps pure white (#FFFFFF) directly to absolute black (#000000), allowing OLED and AMOLED displays to turn off pixels entirely to maximize battery life. Reader Slate Dark maps background tones to a soft dark-charcoal (#18181B) and text to off-white (#E4E4E7) to eliminate harsh contrast and minimize eye strain in dim environments.
Yes. High-DPI page rasterization ensures that typography, charts, vector diagrams, and annotations remain sharp, legible, and clear across desktop monitors, tablets, and e-readers.
Yes. Elixuvo allows free dark mode conversions for standard documents up to 50 MB and 1,000 pages without watermarks, sign-ups, or hidden restrictions.
No. All inversion and document compilation occur strictly in-memory (RAM) inside ephemeral execution containers. No files, logs, or intermediate images are ever saved to disk or persistent databases.
