Split double-page scans
Organize

Cut scanned spreads into left/right or top/bottom pages

Separate evenly scanned book spreads

A five-page PDF contains ten book pages, arranged evenly as left and right scans. Choose left/right and normal half order. Expect ten output pages. Inspect the gutter for clipped lettering and remember that the split hides, rather than securely erases, the opposite half.

✓ Output should have twice the source page count. Inspect text near the midpoint on rotated pages and confirm half ordering.

Make it work for your document

Options after selecting a file

Split direction

Left/right or top/bottom.

The midpoint is fixed; uneven spreads may cut into text.

Reverse halves

Swap the two output halves for each source page.

Use for reading direction or scan order, not page rotation.

Frequently asked questions

The details, when you need them.

Can I choose a custom split position?

This version splits at the midpoint only.

Can I reverse left and right output order?

Yes. Enable the reverse-halves option.

Prepare even spreads

The split is at the exact center of the displayed page. It works best when two scanned pages occupy equal halves. This tool does not detect the book spine or deskew the scan. Crop or correct uneven scans first if the midpoint would cut through text. Existing page rotation is taken into account.

Splitting is not erasure

Each result uses a cropped copy of the source page. The hidden half may still be stored in the document and recoverable by changing its boundaries. Do not use this method to remove private information. Use a verified redaction workflow for sensitive content and review the whole output before sharing.

Check the saved result

Output should have twice the source page count. Inspect text near the midpoint on rotated pages and confirm half ordering.

Hidden halves may remain recoverable

Cropping hides the other half but may retain its data. This tool is not redaction and does not detect a spine or deskew.

The split cuts through one book page

The scan halves are unequal. Correct or crop the source scan first; a custom split position is not supported.
