When this tool is useful
Separating book, magazine, ledger, or photocopied two-page scans whose gutter is close to the geometric center of each physical PDF page.
How local processing works
Each source page is embedded as page artwork twice and clipped to equal left and right regions; the halves are placed into new pages in the selected left-to-right or right-to-left order.
How to use it
- Prepare Split scanned PDF spreads: Work from a copy and confirm page width, true gutter position, left-to-right or right-to-left reading order, rotated scans, content crossing the center, source resolution, and the doubled output page count. Keep every source unchanged.
- Run Split scanned PDF spreads: Process only in this browser. Each source page is embedded as page artwork twice and clipped to equal left and right regions; the halves are placed into new pages in the selected left-to-right or right-to-left order.
- Download and verify: Save under a new name. Inspect the gutter and outer edge of every half at high zoom, confirm reading order and exactly two outputs per source page, and reject documents whose content is not centered for this fixed split.
Important limitations
The cut follows the geometric midpoint: it does not detect a curved gutter, deskew pages, remove shadows, run OCR, or identify a single-page scan. Links, forms, tags, annotations, and signatures are not preserved as functional page structures.
