Straighten out a PDF that opens sideways or upside down. Load a file and choose to rotate every page or just the pages you list, by 90 degrees clockwise, 180, or 270, then download the corrected document. This is the fix for scans that came in at the wrong angle, phone captures turned the wrong way, or a mix of portrait and landscape pages that need aligning. The rotation is baked into the file so it stays fixed wherever the PDF is opened, not just in your viewer. Everything happens in your browser with a PDF library loaded in the page, so your document is never uploaded and the change is applied instantly. Your original file stays untouched on your device, and you can re-run the tool with different pages or angles until every page reads the right way up.
