About This Tool
The PDF Scan Aligner is a mandatory utility for sanitizing tilted digital assets and mobile snapshots.
Documents scanned via physical flatbeds or captured quickly with smartphones often carry subtle rotations. Tilted pages look highly unprofessional, hinder text readability, and cause margins to clip during printing.
This tool utilizes robust Radon Transform and Hough Line detection algorithms to scan gradients and text lines under 20ms. It precisely measures skew down to 0.01 degrees and performs pixel-level Canvas rotation, snapping your receipts, contracts, and booklets back into crisp geometric alignment.

Frequently Asked Questions
We run high-speed Hough Line projections on text lines. Since formal prints have clear horizontal spacing patterns, finding the angle with the maximum variance isolates the rotation.
