Split PDF in Half Online Free — PrivaTools

TL;DR: Upload a PDF (typically a two-up scan or booklet) and download a copy with every page cut down the middle.

Split PDF pages in half online for free — split each page horizontally or vertically. Perfect for two-up scans, magazine spreads, and side-by-side layouts.

Split PDF in Half runs on the same privacy-first stack as every PrivaTools utility: files enter an isolated Docker container, are processed in temporary memory, and are unlinked the moment your download begins. No account, no watermark, no daily quota.

How to Split PDF in Half with PrivaTools

  1. Upload the PDF — Select a PDF up to 500 MB. Best for two-up scans or scanned booklets.
  2. Choose direction — Vertical splits each page down the middle (left → right halves). Horizontal splits across the middle (top → bottom).
  3. Split and download — Click Split. The result is a new PDF where each original page is replaced by its two halves in reading order.

Frequently Asked Questions

When would I use this?

For two-up scans (where two pages were scanned side-by-side onto one physical page), scanned booklets, or any PDF where each page should be two pages in the output.

Does it work on PDFs with mixed page sizes?

Yes. Each page is split independently at its own midpoint, so different page sizes work fine.

What's the difference between vertical and horizontal?

Vertical bisects each page down the middle into left and right halves (the common case for landscape two-up scans). Horizontal bisects across the middle into top and bottom halves.
