How to Add Hyperlinks in LaTeX

The fix

Load \usepackage{hyperref} (last in your preamble). Use \url{https://example.com} for a bare clickable URL and \href{https://example.com}{link text} for a labelled link. hyperref also turns \ref, \cite, and table-of-contents entries into clickable links automatically.

Example

\usepackage{hyperref}     % load LAST
\hypersetup{colorlinks=true, urlcolor=blue, linkcolor=black}
% ...
Visit \url{https://letx.app} or the
\href{https://letx.app/learn}{learn hub}.

Frequently asked questions

Why should hyperref be loaded last?

hyperref redefines many commands, so loading it last (with a few known exceptions like cleveref) avoids clashes. If links break, check the load order first.

How do I colour links instead of boxing them?

Use \hypersetup{colorlinks=true} and set urlcolor, linkcolor, and citecolor. Without it, hyperref draws coloured boxes around links that do not print well.
