Reader Mode is a general feature available in most of the popular browsers. It basically declutters a webpage by removing unnecessary contents such as advertisement. Safari first included the Reader Mode back in 2010, followed by Microsoft in 2015 and recently Firefox in 2017.
All of them allows users to change the background colour, font size and font type to provide a comfortable reading environment. Now the same feature has been spotted in Chrome’s experimental Canary release. We can expect the feature to be ported into the stable version soon. If you are already using Canary then you can toggle the feature on “chrome://flags/#enable-reader-mode”. After that, all you need to do to enter Reader Mode is to click on the settings button on the top right and choosing the “Distill Page” option.
