Is this like dark mode for PDFs?

Yes. Inverting colors transforms white-background documents into dark-background versions, which is easier on the eyes when reading on screens in low-light environments. Dark text becomes light, and white backgrounds become black or dark gray.

Will this save toner when printing?

Inverting a document with a white background creates a mostly-black output, which actually uses more toner. However, inverting documents that already have dark backgrounds (like presentations with dark themes) can save toner by converting them to light backgrounds.

Does inversion affect images?

By default, all page elements including images are inverted. This creates a negative effect for photos. If you only want to invert the background and text, use the selective inversion option to leave images unchanged.

Is inverted text still searchable?

Yes. The text data in the PDF is not modified by the visual inversion. Text remains fully searchable and selectable in the inverted output.
