A book scanned two pages at a time, or a booklet printed two-up, needs each spread cut down the middle to read properly on a screen. Split in Half crops every page of a PDF into two single pages, left and right, automatically.

Frequently asked questions about split in half
Does this work for landscape spreads too?
Yes — choose a horizontal split for spreads that need dividing top and bottom instead of left and right.
Will the page order come out correct?
Yes, each spread's left half is placed before its right half, keeping the document in correct reading order.
Is there a page limit?
It runs entirely in your browser, so it's bounded by your device's memory rather than a server-side limit.
Are my files uploaded anywhere?
No — the split happens locally, so your document is never uploaded.
