Frequently Asked Questions
Does this invert images and color diagrams as well as text?
Color inversion mathematically maps every color channel to its photographic negative, turning white backgrounds pitch black.
Are private textbooks or confidential reading materials uploaded?
No. Color inversion operates 100% locally in your browser memory via WebAssembly. Your documents never touch external servers.
Will inverted documents save battery power on OLED displays?
Yes. Rendering true black backgrounds allows OLED and AMOLED smartphone and tablet screens to turn off black pixels, saving battery.
