Split in Half
Split in Half divides wide or double-page layouts into two standard portrait pages, cutting either vertically (left and right) or horizontally (top and bottom). It is the standard fix for two-page spreads produced by book scanners.
How to use Split in Half
- Upload the scan containing double-page spreads.
- Choose a vertical split for left/right spreads or horizontal for top/bottom halves.
- Run the split and download the resulting single-page document.
Where Split in Half is useful
- Turning scanned book spreads into individually readable A5-style pages.
- Separating a scanned newspaper spread into two columns of pages.
- Splitting landscape spreadsheet printouts into two portrait halves.
Formats, algorithms and limits
Each page is duplicated and its visible area is reduced to one half through the page's crop box, so the underlying artwork is preserved at full resolution in both halves. The result is a document with twice as many pages as the source.
Troubleshooting and honest limits
- Check that no content sits exactly on the fold — a small centre margin loss is normal for scans.
- Use vertical splitting for spread scans and horizontal only for stacked layouts.
- If the halves come out in the wrong order, run Organize PDF afterwards to reorder them.
Frequently asked questions
Why does the file have twice as many pages?
Because every source page produces two output pages: one showing each half. That is expected for a spread-to-single-page conversion.
Is image resolution reduced by splitting?
No. The page content is copied unchanged and only the visible area is narrowed, so each half keeps the full scan detail.
Can I split only some pages of a mixed document?
Run the split on a document that contains only the spreads — use Extract pages first to isolate them.
Which direction should I choose?
Vertical for spreads where left and right pages sit side by side; horizontal when two pages are stacked top and bottom, as with some landscape printouts.
