Convert PDF to Landscape

Orientation is the visible consequence of two things: the page's media box, which gives its width and height, and its /Rotate value, which turns the displayed result. A page can therefore read as landscape either because it is genuinely wider than it is tall or because a tall page has been rotated a quarter turn. This tool takes the rotation route without re-rendering page content: it inspects each page's effective orientation and writes a quarter-turn only to pages currently presenting as portrait, leaving true landscape pages alone. The whole file is still loaded and saved, so time and memory use depend on the document and device. That selectivity is the whole point — blanket rotation would flip a report's existing charts onto their sides. Content does not reflow or change size; text and drawings turn sideways with the page instead of being rearranged to fit a wider layout. When you need a genuinely different paper geometry rather than a turn, PDF Page Size Changer is the right tool.
