What is PDF deskewing?

Deskewing is the process of correcting tilted or rotated pages in scanned documents. When you scan a document, it's common for pages to be slightly skewed. This tool automatically detects and corrects that skew.

How accurate is the skew detection?

Our tool uses OpenCV's advanced image processing algorithms to detect skew angles with high precision. It works best on documents with clear text content.
