The programs that we have talked about in these lines, whether open source or not, focus on offering us specific functions related to reading PDF . As we have seen, some of them also offer us some additional functions for the basic editing of these specific documents, which is very useful.

With this, what we want to tell you is that practically all browsers such as Chrome, Firefox or Edge, among others, can open PDF for free.

Of course, we must bear in mind that these programs to move around the Internet are limited to that, to show the content, little else. In the best of cases we can zoom on them, but nothing of the tasks that we can find in other more specific viewers.

Edge Chromium, an increasingly powerful PDF reader

But we will always find some cases more advanced and complete than others for this type of specific task. We refer specifically to the functions for reading and processing these files in PDF format that each of the web browsers proposes to us. In fact, it could be said that one of the companies that is trying the most in this regard, at Microsoft . Logically this is done through its new Edge based on Google’s Chromium.
