Split scanned book spreads into single pages

Keep original page content

The tool changes the visible area of each copy of a source page. It does not turn the page into an image, so existing text remains searchable.

Left-to-right or right-to-left

Use left-to-right order for most English books. Choose right-to-left for manga and other books that begin on the right half.

Keep single-page covers

Auto mode splits landscape spreads for a left/right split. Keep the first or last page intact, or override the decision on any thumbnail.

How to split PDF pages in half

  1. Choose your PDF

    Drop one PDF into the tool or click Choose PDF. Your file is opened in your browser without uploading it.

  2. Check the split line and output order

    Choose Left / right or Top / bottom. The red line shows the cut; thumbnail numbers show the output order. Adjust the line if the scan is off-center.

  3. Split and download

    Click Split and download to save all output pages in one PDF. The file name ends with _split.pdf.

03

Fix reversed pages or an off-center gutter

Setting Output order Best for
Left to right Left half, then right half Most English books, magazines, and catalogs
Right to left Right half, then left half Manga and right-bound or vertically written books

The split position can be adjusted from 40% to 60% in 0.5% steps. Try 49% or 51% when the book gutter does not line up with the middle of the scan.

Split spreads versus combine pages

Split PDF spreads

Turn one two-page scan into two individual pages for reading on a phone or e-reader.

Splitting changes visibility, not the underlying content. The hidden half remains in the PDF. Use Redact PDF when content needs to be removed.

Frequently asked questions

QDoes splitting a spread reduce quality?

No rasterization is performed. Existing text, graphics, and images retain their original form. Existing text can still be searched or copied.

QIs the hidden half permanently removed?

No. The hidden half remains in the file and can be revealed by changing the visible page area in a PDF editor. Use Redact PDF to remove sensitive content.

QCan I keep the cover as one page?

Yes. Keep the first and last pages intact with the cover options, or turn splitting off on individual thumbnails.

QCan I split PDF pages horizontally?

Yes. Choose Top / bottom. Auto mode then targets portrait pages; choose Split every page to include all orientations.

QCan I use it on my phone?

Yes. The controls support touch input. Large PDFs may need more memory than a phone has available; try fewer pages or use a computer.

QIs my PDF uploaded?

No. Loading, previews, processing, and output generation take place in your browser. No account or installation is required.
