WebZIP downloads the entire web just as it is shown on the browser. It doesn't perform screen captures nor does it resize anything, it simply downloads the code, the images, the styles and all the files that will be necessary to be later show the page in an identical way to how we would see it on a browser.
One of the advantages of having webs saved on the hard drive is how quick they load, together with the possibility to maintain the user within the boundaries that we set for him. Something very interesting to save the websites that are visited by children or on showcase computers. WebZIP can download as many pages as we want, creating a project for each of them and it's capable of downloading all the contents that are behind the links so as to make sure that the browsing isn't broken when one is followed.
And of course, any website downloaded with WebZIP can be used on the browser integrated within the program.
