Red box around chapters in table of contents and references in pdf document

Question

I would like to know how I can remove these red boxes that appeared in my document after inserting \hyperref.

Boa tarde. Gostaria de saber como posso retirar estas caixas em vermelho que apareceram no meu documento, após inserir o \hyperref.

Answer 1

You can remove the boxes (not every PDF viewer draws them) by adding

\hypersetup{pdfborder=0 0 0}

Example

\documentclass{amsbook}
\usepackage{hyperref}
\hypersetup{pdfborder=0 0 0}

\begin{document}

\frontmatter
\tableofcontents

\mainmatter

\chapter{Title}

\section{Title}

Some text

\end{document}
