PDF deskewing is the process of correcting tilted or skewed pages in scanned documents. It straightens the content to make it easier to read and process.
Our tool uses OpenCV's advanced algorithms that can detect skew angles with sub-degree precision. You can adjust the sensitivity threshold based on your needs.
Yes! All processing happens entirely in your browser using WebAssembly. Your files never leave your device and are not uploaded anywhere.
Higher DPI means better accuracy but slower processing. 150 DPI is recommended for most documents. Use 300 DPI for documents requiring maximum precision.
