Split PDF Pages in Half
Cut every page of a scanned PDF vertically or horizontally into two separate pages in seconds. Free, no signup — it works in your browser.
Everything runs inside your browser — your file is never uploaded to a server.
About this tool
This tool is built for scanned books, magazines and A3 spreads that were digitized as a single wide or tall page covering two logical pages. Choose whether each page should be split vertically into left and right halves or horizontally into top and bottom halves, and the tool renders a brand-new PDF where every original page becomes two full-size pages in the correct reading order. A right-to-left toggle flips the order of the halves for Arabic, Hebrew, or manga-style scans so pages land in the sequence you'd actually read them. Because it runs entirely on pdf-lib in your browser, a scanned family archive or an out-of-print book never has to be uploaded anywhere to be split apart. The result is a document that reads naturally on a phone or e-reader instead of forcing you to zoom and scroll across an oversized spread.
How to use this tool
1. Upload your scanned PDF
Add the PDF containing wide or tall combined spreads.
2. Pick a split direction
Choose vertical for left/right pages or horizontal for top/bottom.
3. Set reading order if needed
Enable right-to-left order for Arabic, Hebrew or manga scans.
4. Download the split PDF
Save a new file where every spread is now two separate pages.
Why use this tool
Scanned spreads that cram two pages into one image are uncomfortable to read on any screen smaller than the original book, forcing constant zooming and panning. Splitting each page in half turns that awkward file into a normal single-page document that flows naturally on a tablet, phone, or e-reader, and it does so without ever sending your scans to a server.
Tips & best practices
- Check a couple of split pages before relying on the whole file, since unusual scan margins can shift the exact center line.
- Use the right-to-left option for Arabic, Hebrew, Japanese manga, or any publication that reads back to front.
- Combine this with the page reordering tool afterward if your scanner captured spreads in reverse page order.
Common use cases
- Turning a scanned two-page-per-image novel into single readable pages for an e-reader.
- Splitting digitized magazine spreads for easier viewing on a phone screen.
- Preparing an out-of-print manga scan with correct right-to-left page order.
- Converting oversized A3 architectural scans into standard single sheets.
- Fixing old photocopied documents that were scanned two pages at a time.
Frequently asked questions
What kind of PDFs need this tool?
Books or magazines scanned with two facing pages captured as one wide image per PDF page are the most common case.
Can I split horizontally instead of vertically?
Yes, choose the horizontal option to split top and bottom instead of left and right, useful for tall stacked spreads.
What does the right-to-left option do?
It reverses the order of the two resulting halves on vertical splits so right-to-left reading books stay in the correct sequence.
Will the split affect image quality?
No, each half is rendered from the original embedded content at full resolution, so nothing is downscaled or recompressed.
Does the number of pages double after splitting?
Yes, every original page becomes two pages in the output file, since each half becomes its own full page.
