Make a dark-mode version for comfortable night reading
Reader dark modes often only tint the background and leave images, diagrams and scanned pages glaringly bright. Inverting the file itself is consistent across every page and works in any reader, on any device, including e-ink.
Yes - inversion is a photographic negative, so photos come out looking like film negatives. It suits text documents, papers and code listings; it does not suit image-heavy brochures.
Running the tool a second time returns the original colours, but each pass re-renders the pages, so quality does not improve by going back and forth. Keep your original.
No. Pages are redrawn as images, so text is no longer selectable or searchable and links and form fields do not survive.
