Most PDF dark modes just invert everything, so photo and charts turn into negatives. I built Candlepage o darken only the page and leave the pictures alone.Works on web and local PDFs, free, in English and Herew.

Could you build this?

Yes The approach uses PDF.js rendering with a CSS or canvas filter that darkens the page background and skips detected image regions. This is a well-defined technical problem that a capable vibe-coder can build, with some tuning needed for edge cases.
