About PDF dark mode

Recolours every page of a PDF so long reading sessions are gentler on the eyes: white-on-dark, pure black or a warm sepia tone. It is useful for late-night study or e-reader screens. Text and images are inverted together, so photos can look odd, which is normal for any inversion.

How to use PDF dark mode

  1. Open the PDF you want to read at night.
  2. Pick a dark, black or sepia look for the pages.
  3. Save the converted PDF and open it on any device.

Frequently asked questions

Why do the pictures look strange in dark mode?

Inversion flips all colours, including photos, so they look like negatives. If images matter, try the sepia option, which keeps their tones much closer to the original.

Which mode is best for reading in bed?

Sepia is gentler for long text, while dark or black reduce glare the most. Try dark first, and switch to sepia if white text on a black page tires your eyes. Lower screen brightness helps too.

Can I go back to the original colours?

The converted file has the new colours built in, so keep your original PDF. You can always run the tool again on the original with a different mode if you change your mind.
