About This Tool
Deskew PDF automatically detects and corrects tilted or skewed pages in your PDF documents. This is essential for scanned documents that were fed into the scanner at an angle.
The tool uses advanced image analysis to detect the exact rotation angle of each page and corrects it to vertical alignment. You can adjust the sensitivity threshold and DPI settings for optimal results.
All processing happens locally in your browser using WebAssembly technology, ensuring your documents remain private.
