How to take a full-length screenshot of a web page in Linux

Last updated on November 26, 2020 by Dan Nanni

Are you trying to capture a screenshot of a web page? You could screen capture the web page manually after loading it on a web browser. However, if the layout of the web page does not fit into the screen of your computer, the screenshot wouldn't cover the whole page, but only part of it.

In Linux, there is a GNOME application called gnome-web-photo that can generate a full-size screenshot or thumbnail of a website or any URL.

In this tutorial, I will describe how to take a full-length screenshot of a web page by using gnome-web-photo.

Since gnome-web-photo is a GNOME application, you need to use a desktop environment in Linux.

Install gnome-web-photo on Ubuntu or Debian

$ sudo apt-get install gnome-web-photo

Install gnome-web-photo on Fedora

$ sudo yum install gnome-web-photo

If you are a CentOS or RedHat user, be aware that gnome-web-photo depends on GTK+ 3.0. This means that gnome-web-photo is not compatible with GNOME 2, which is shipped with CentOS/RHEL 6 and higher.

To take a screenshot of a web page:

$ gnome-web-photo -t 0 --mode=photo http://www.washingtonpost.com output.png

The -t option specifies the timeout value (in seconds) for screenshot generation. -t 0 means that timeout is disabled.

Using gnome-web-photo, you can also generate a small thumbnail of a webpage as follows. Optionally, you can specify thumbnail size by using -s option. The default thumbnail size is 256x256.

$ gnome-web-photo -t 0 -s 128 --mode=thumbnail http://www.washingtonpost.com output.png

If you want to save a screenshot of a website as a multi-page PDF, so that you can print it out later, you can use the following command.

$ gnome-web-photo -t 0 --mode=print http://www.washingtonpost.com output.pdf
