I am trying to extract all the content of a website (HTML, CSS, JS) (images and videos will be a plus).

I am looking for a tool like HTTrack but that can access pages that require a login (I have the POST parameter's values). Does anyone know a tool like this?

If that is not possible, does anyone know a browser extension (for Chrome or Firefox) to save automatically the content of a website while browsing it? (Sort of an offline reader, but that really grab the HTML, CSS and JS.)

HTTrack supports form-based and HTTP authentications:

    Thank you for your quick answer! I have tried the "Form-based authentication" with IE before but it was not working. And it worked just fine with Firefox now. So it perfectly solved my problem! I will have a look at GNU wget as well

You can use GNU wget:

  • free and open source
  • Linux, Windows, Mac (brew install wget)
  • CLI
  • supports authentication, e.g. wget http://myurl.com --user=joe --password=schmoe or with wget --save-cookies + wget --load-cookies
