Modufile's Rotate PDF tool lets you change the orientation of pages in a PDF document directly in your browser. You can rotate all pages by 90°, 180°, or 270° with a single click. The tool modifies only the page rotation metadata — no content is altered or re-rendered — so the operation is lossless and instant. It runs entirely client-side, which means your PDF is never uploaded to a server. This is ideal for fixing scanned documents that came in sideways, correcting page orientation before printing, or rotating a PDF from landscape to portrait.
