How to take screenshot of complete webpages?

On recent versions of Firefox, there is no need for any plugins. This capability is built into the browser.

1. In Firefox, use Ctrl+Shift+F2 to open the Web Developer Console.
2. Type :screenshot --fullpage (this will autocomplete, so :s Tab --fullpage will work).

That will save the screenshot as a PNG file to your downloads folder. By default, the filename includes the date and time. You can use a different filename if you wish, simply by passing it in on the CLI: :screenshot --fullpage my_name.png.

This will also work on pop-up windows, but each window will need to be saved individually. I know of no way to combine them into a single screenshot. (You could, of course, do that in GIMP or another image-editing tool later.)

Here a list of applications that you can use from terminal:

• wkhtmltopdf (source)

wkhtmltopdf is a command line utility that converts html to pdf using webkit rendering engine.

sudo apt-get install wkhtmltopdf

• wkhtmltoimage (source)

The wkhtmltoimage utility shall take the screenshot of a given url, and save it as a png image. It uses the webkit rendering engine.

Other options :

wkhtmltoimage provides many options to customise the screenshot. Some examples are as follows :

For anyone who came here looking for a CLI option: There is no need for any other tool, latest version of both chrome and firefox have inbuilt abilities.

Chrome

/path/to/chrome --headless --screenshot="img.png" "www.stackoverflow.com"

FireFox

/path/to/firefox -screenshot img.png www.stackoverflow.com

That's it.
