About the Halve PDF Pages
When a book is scanned two pages at a time, or a document is printed two pages per sheet, each PDF page holds two real pages side by side. This tool cuts every page into two halves, down the middle or across, and puts them in reading order, so the PDF has one real page per PDF page. You can keep the cover and the back page whole, and reverse the order for right-to-left books. Nothing is redrawn: the halves are made by adjusting the page frame, so text and images stay exactly as sharp as before.

Typical uses
Scanned books and magazines, documents printed two pages per sheet, booklet scans, and A3 spreads that need to become A4 pages.
- Scanned books: down the middle, left first
- Right-to-left books: down the middle, right first
- Top and bottom layouts: across
Covers and back pages
Book scans often start with a single cover page. Tick Keep the first page whole so the cover isn't cut, and do the same for a single back page.
Rotated pages
If pages are stored rotated in the PDF, the tool works out left and right as you see them on screen, so the halves come out in the right order.
Afterwards
Use Rearrange PDF Pages if a few pages are out of order, or Delete PDF Pages to remove blank halves.
How it works
Every PDF page has a box that says which part of the page is shown. The tool makes two copies of each page and sets the box of the first to the left (or top) half and the second to the right (or bottom) half. Readers then show and print only that half, at full quality.
Printing the result
Each half keeps its real size, so printing at actual size gives pages of the original book size. If you want them larger, choose fit to page in the print dialog.
Phone and computer
Splitting is fast on any device because no page is redrawn.

Frequently asked questions
Will the quality drop?
No. The halves are made by changing the visible area of each page, so the original text, vectors and images are untouched.
Can I split A3 into two A4 pages?
Yes. Cutting an A3 landscape page down the middle gives two A4 portrait halves.
What if the halves aren't exactly in the middle?
The cut is always in the exact middle. If the scan is off-centre, use Crop PDF first to trim the edges evenly.
Why is right-first useful?
Books in Arabic, Hebrew, Japanese and other right-to-left languages are read from the right page first.
Will the file get smaller?
No. Each half still contains the whole original page, with the other half hidden; that is what keeps it lossless.
Does it work with password-protected PDFs?
Remove the password first with our Unlock PDF tool, then come back.
Is my PDF uploaded?
No. Everything happens in your browser, so the PDF stays on your device.
Does it work with portrait pages?
Yes. Choose Across to cut portrait pages into a top half and a bottom half, for example for documents printed two-up vertically.
Can I split only some pages?
The tool halves every page except an optional first and last page. To split only some, use Split PDF first, halve that part and merge the parts again.
