Create or duplicate a shortcut to SumatraPDF (and optionally, give it a different name) in a location of your choosing.

With a simple shortcut switch, SumatraPDF can invert all colours within the document and this colour inversion is not limited to text, but also extends to embedded images too. Now this is where I found SumatraPDF to be an absolute lifesaver. Images in these readers are usually rendered untouched with a jarring white background. But this in no way changes how images embedded within the PDF are displayed. I think I've lost count on the number of times I wished PDFs or readers had a high contrast mode with white text on a black background.Īdobe Reader, Foxit Reader and the likes have a halfway solution by giving options for replacing the text background/foreground colours.

This is because most PDFs have black text on a white background which is in no way easy on the eyes. In my personal experience, I've found the extended reading of PDF files on-screen to be an extremely daunting and tiring task. Besides the obvious PDF files that SumatraPDF can open, it can also be used to view ePub, Mobi, XPS, DjVu, CHM, CBZ and CBR files. SumatraPDF is a free, open source and a tiny document reader for Windows.
