iXzenoSQ: Is there any 'dark mode' or document color inversion feature in UPDF?
Does UPDF have such a feature?
Most text documents have white backgrounds that can be blindingly bright (especially when viewing for a long time).
Hence it would be really helpful to have a feature that will essentially display the document in dark mode (like an inversion or accessibility feature).
Adobe Acrobat has this in their settings: Accessibility > Document Colors Option > Replace Document Colors.

Nov 21, 2025A: Hi, UPDF supports dark mode. If you want to change the software interface to dark mode, please go to Settings > General > Dark. If you also want to switch your PDF file to dark reading mode, go to the View option right below General, find Background & Display, and select Dark Mode to apply a dark, eye-friendly theme to the entire PDF.
