How to Rotate PDF Pages

Introduction

From time to time, you may come across a PDF document or a specific page in a PDF document that has the wrong orientation. To correct the orientation, you may want to rotate the whole document or the page in question.

Some browsers like Firefox, MS. Edge, and Google Chrome allow users to rotate PDF files, for viewing only, but without enabling them to maintain the new orientation.

Objective

This lesson aims to show you how to build a PDF rotator tool using a lightweight command-line-based utility developed in the Python programming language.
