How to split scanned book spreads
- Click Choose files (or drag & drop) and select one or more PDF files. You can also paste them from your file manager.
- Choose whether each page is split down the middle or across it, and the reading order of the two halves — left-to-right for most books, right-to-left for Arabic and Hebrew.
- Press Split the pages. Processing runs with a live progress indicator.
- Open the download page to save your files individually or grab everything as a single ZIP.
Why split pages in half?
Book and magazine scans arrive as spreads: two facing pages captured as one wide page. They are awkward to read on a phone and worse to print. This cuts each page in half and keeps the halves in reading order, with an option for right-to-left binding so Arabic, Hebrew and Japanese scans come out the right way round.

About the formats
Scanned like a book, read like a book
Almost every book scan has the same problem: the scanner saw an open book and recorded one wide image of two facing pages. It is a faithful record and a miserable reading experience. On a phone or an e-reader each spread shrinks to fit the screen, which makes both pages half-size, and no amount of zooming fixes the fact that the device is paging through sheets rather than pages.
This tool cuts every page down the middle and emits the halves as separate pages, so a 90-page scan of a 180-page book becomes a 180-page document that behaves the way the book did. The same applies to anything printed two-up: conference programmes, scanned newspapers, sheet music, and old documents photographed a spread at a time.
Splitting across, and reading right to left
Not every spread is side by side. Landscape slides scanned two to a sheet, and folded programmes, are stacked — for those, splitting across gives you top page then bottom page. And not every document reads left to right: Arabic, Hebrew, and Japanese books, manga included, open the other way, so the right-hand half comes first. Choose that and the halves are emitted in the order the book was meant to be read.
Where the cut falls
The cut is the exact geometric middle of the page, which is the right answer when the scan is square and the gutter is centred. It is the wrong answer when it isn’t — a book held down by hand, a page photographed at a slight angle, or a scan where one side was trimmed. Nothing is lost when that happens, because both halves are kept and the content is simply divided at the wrong point, but it is worth checking the first page before trusting a long document. Content that genuinely crosses the middle, such as a diagram spanning both pages, will be divided too.
Frequently asked questions
Is this Split PDF Pages in Half tool free?
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Can I process multiple PDF files at once?
Yes. Add as many files as you like — each one is processed in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
Does editing re-compress my PDF or reduce its quality?
No. Pages are copied at the object level — text, fonts, images and vector content are carried over as-is, without re-rendering. The output keeps the same sharpness and searchable text as the original.
What if only some pages are spreads?
Every page is cut, so mixed documents come out uneven. Split the spreads into their own file first with Extract PDF Pages, halve that, then merge the parts back together.
