Free, no uploads, no sign-up. Runs 100% in your browser.
How Split Pages in Half works
Each page is copied twice and each copy is cropped to one half by changing its page box with pdf-lib. Nothing is re-rendered, so quality and text are untouched.
Input: PDF. Output: PDF.
How to use Split Pages in Half
- Drop your PDF onto the Split Pages in Half area, or click to choose it.
- Wait a moment while page thumbnails render locally.
- Choose the pages and options you need. Previews update as you go.
- Press the main action button and download the finished PDF.
Tips
- Encrypted PDFs must be unlocked first with Unlock PDF.
- Large scanned PDFs are mostly images. Compress PDF shrinks them the most.
- Your original file is never modified; you always download a new copy.
Split Pages in Half FAQ
- My book reads right to left. Can I change the order?
- Yes. Turn on "Right page first" and the right half comes before the left half.
- Are my files uploaded?
- No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
- Is it free? Are there limits or watermarks?
- Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
- Does it work offline?
- Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
