Correct rotation angle of scanned PDF pages that are slightly crooked.
Deskewing a PDF corrects pages that were scanned at a slight angle — the most common problem with flatbed scanner output. Even a 2-degree tilt makes a document look sloppy and can interfere with OCR accuracy.
Office administrators deskew batches of scanned contracts and letters before archiving. Researchers deskew scanned academic papers before running OCR. Legal clerks deskew court document scans before electronic filing. Anyone processing large volumes of scanned documents benefits from automatic deskewing.
Our deskew algorithm detects the rotation angle of each page and corrects it automatically. Pages are rotated by the detected amount and the result is a straight, professional-looking document. All processing is done in your browser.
Your files never leave your browser. No account required, no server uploads — just fast, local processing. This is what it means to deskew PDF without uploading.
Makes messy phone or flatbed scans look like native digital documents.
Currently you must provide a manual correction rotation angle in degrees.
