Its new updates of Chrome 62 and its really easy to take screenshots with build in api, no longer require any plugins or extensions.
Open up your chrome, usually I would use Chrome Canary which has latest versions. open up your console with
Shift + Control/Command + I
Then use the inspector to select element that you want to take screenshot, if you choose to take whole page, just select “body” tag.
bring up the command using
Control/Command Shift + P
