Changing page orientation fixes documents that appear sideways or upside-down, making them readable without awkward head tilting or device rotation. You'll encounter this frequently with scanned documents, mobile-captured PDFs, or files created across different devices.
Beyond basic readability, proper orientation ensures professional presentation when sharing documents with clients or colleagues. It also prevents printing mishaps where pages emerge incorrectly oriented, saving paper and time. When you're compiling multi-source documents into a single PDF, consistent orientation creates a polished, cohesive final product that flows naturally from page to page.
