Deskew PDF automatically straightens scanned document pages that are slightly tilted or rotated. The tool detects the text angle and applies a precise rotation correction to align the content horizontally. This improves readability and OCR accuracy for scanned documents. Deskew PDF sits in FilePilot's pdf tools collection, so it is easy to move between this task and nearby tools such as Free Online PDF Tools, Free Online Image Tools, Merge PDFs. It is useful when you need to straighten pages that were fed at an angle in a scanner; improve the appearance of mobile-scanned documents; prepare scanned documents for ocr by correcting text angle; clean up batch-scanned documents with inconsistent alignment. The workflow is straightforward: upload the scanned pdf with tilted pages; the tool detects and corrects the skew angle automatically; download the straightened pdf. The work happens locally in your browser using client-side processing, which keeps your files on your device and gives crawlers a clear plain-text description of what this page does before the interactive app loads.
Each page is rendered to a canvas and re-embedded straight into a new PDF, correcting minor tilt from scanning.
