How to get rid of the red box around hyperlink in PDF?

Question

I have a pdf file obtained from the network and it has red boxes around links.

How can I get rid of them? How can I view the document without them?

P.S. Something that I found:

• pdf is probably generated by latex,

• non-commercial software is limited in modifying the document.

Update:

Facts disagree with the opinion that only author can change the way pdf looks. Below is an example of the same document in google chrome.

Answer 1

The document in your screenshot seems to have been created with LaTeX.

If you have the source code of the document, you can disable those red borders around links using

\usepackage[hidelinks]{hyperref}

Here's the documentation on the package hyperref.

Answer 2

Open it in Chrome browser. If there is no red rectangle anymore, then print it in the browser. Next change the option to "save as PDF". It works for me.
