Split PDF Pages in Half (Scanned Book Spreads) by AIMerger

Scanned a book or magazine two pages at a time? Split every spread into separate left and right pages — or top and bottom — in reading order. Covers can stay whole, right-to-left books are supported, and nothing is redrawn: each half is the original page, just trimmed.

Limits on this device

Up to about 1,500 pages on a computer, less on phones. Links and form fields inside the pages don’t survive N-up, booklet and fit-to-paper layouts (the pages are placed as drawings); splitting in half keeps them. Password-protected PDFs need the password removed first.

Split PDF Pages in Half — a real example made with this tool from sample files

A scanned two-page spread → separate left and right pages, without re-rendering.

How to use the page splitter — 4 steps

  1. 1

    Add the PDF with the spreads.

  2. 2

    Choose Left | right (book spreads) or Top / bottom. Keep “Only split pages that are wider than tall” on so single pages are left alone.

  3. 3

    Tick “Keep the first page whole” for a front cover, and “Right-hand half first” for right-to-left books. Check the preview.

  4. 4

    Press Split pages and download.

💡 Tip: If the gutter (the middle of the spread) cut off a few letters, add 2–3 mm of overlap so each half keeps a little of the other side.

Lossless splitting

Most splitters re-render pages as pictures, which blurs text and makes files bigger. Here, each half is a copy of the original page with its visible area (the crop box) set to that half — the text, images and drawings inside are untouched, so there is no quality loss and text stays selectable. Page rotation is respected, so sideways-scanned spreads split correctly.

Covers and odd pages

A scanned book often starts with a single front cover and ends with a back cover; tick the options to keep them whole. Pages that are taller than wide are left as they are when “Only split wide pages” is on. If you need to reorder afterwards, continue in Organize PDF.
