Locate the Deskew Filter for Monochrome Documents
Use this method if you are attempting to deskew and optimize an existing black-and-white (monochrome) PDF document.
Acrobat categorizes document processing features depending on how the document was imported. For standard monochrome PDFs, the deskew feature is hidden within the optimization filters.
Open your PDF in Acrobat, navigate to the Tools menu, and select Document Processing.
From the Document Processing panel, click on the Optimize Scanned PDF option.
Click on Filters, then select Edit to view the advanced image correction settings.
Locate the deskew settings, make your adjustments, and click OK twice to apply the filter to your document.
Apply Deskew via Custom Scan Settings for Color and B&W
Use this method to automatically apply the deskew filter while actively scanning a new color or black-and-white document.

Frequently Asked Questions
Why do my scanned PDFs need deskewing?
Scanned documents often become skewed (crooked) due to misaligned paper in the scanner's automatic document feeder or uneven placement on the flatbed scanner glass.
Can I apply the deskew filter after the document has already been scanned in Acrobat?
Yes, you can use the Optimize Scanned PDF tool located under the Document Processing menu to apply deskew filters to existing PDF documents.
Does deskewing affect the clarity of my scanned PDF?
Deskewing involves slight image rotation which can theoretically cause minor blurring; however, PDF optimization tools usually sharpen the text simultaneously to maintain or improve overall clarity.
