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.

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.
