Straighten crooked scanned pages

Upload a scanned PDF or image file and download a straighter PDF copy when the page leans a little left or right.

Free Deskew Scan Tool

Useful for receipts, letters, forms, and office scans that came out a few degrees crooked.

Before & after

Before and after — a crooked scan aligns with a horizontal line so text rows sit straight.
The page is rotated a few degrees so the text lines match the edges—not the same as rotating a sideways page 90° (use Rotate PDF for that).

Leave blank to auto-detect. Use values like -2 or 1.5 if you want to control it yourself.

Example use

You scanned a receipt, letter, or form and the page is tilted slightly. This straightens it into a cleaner PDF for filing or sharing.

Good for

Scanned receipts, contracts, forms, office paperwork, and camera-based scans that are almost straight but not quite.
