About Change colours
This tool changes the colours of a PDF's pages to make them easier to read, for example white text on black for night reading or yellow on black for high contrast.
- What you add
- One PDF file.
- What you get
- One PDF with the new colours.
How to use it
- Add your PDF.
- Choose the change and the colour scheme.
- Choose the resolution and pages, then start.
- Download the PDF.
Settings
- Change: invert colours, high contrast, custom colours, or shades of grey.
- Colour scheme: white on black, black on white, yellow on black, green on black or black on yellow.
- Custom: a text colour for the dark ink and a background colour for the paper.
- Resolution (dpi) of the redrawn pages, and the pages to change.
Good to know
- Inverting, high contrast and custom colours turn the pages into images, so their text can't be selected.
- Shades of grey keep the text as text.
