SpreadSplit for IOS

SpreadSplit turns landscape PDF spreads into clean portrait pages — exactly the way you want them.

Scanned books, photocopied lecture notes, digitised magazines: they all come out as landscape spreads where two pages sit side-by-side on one PDF page. SpreadSplit splits each spread precisely in half — or wherever you drag the line — and exports a new PDF with all the pages in the right order.

HOW IT WORKS
Open any PDF from your Files app or iCloud Drive. Drag the orange line to set the split position. Both output pages update live. Tap Export and choose where to save. Done.
