Frequently asked questions

Why invert a PDF?
Reading a bright document in the dark strains the eyes, and many readers can't invert the PDF itself. A dark version is comfortable at night and saves battery on OLED screens.
What happens to pictures?
All page colors are inverted, photos included — they will look like negatives. The tool suits text documents and diagrams best.
Will the text stay selectable?
No: pages are rasterized for a guaranteed result, as with scanning.
