Split PDF Down the Middle
Cut each PDF page exactly at the center — left/right or top/bottom. Perfect for book scans and symmetrically formatted documents.
Why Split a PDF Exactly at the Center?
Center splitting works best for documents that are perfectly symmetrical — each half contains equal content.
A 50% split position ensures that both resulting pages have exactly the same dimensions, which is essential for consistent reading, printing, and formatting.
Use this when your scanned pages have equal left and right (or top and bottom) content regions.
