PDF Split & Extract: PageSplit

PageSplit does one job perfectly: it takes a PDF apart. No subscription. No account. Works offline. Your data never leaves your device. Import any PDF and see every page as a thumbnail. Tap the pages you want and extract them into a new PDF. Split a long document by page ranges (like 1-3,7,9-12) or into equal chunks of any size. Drag pages into a new order and save a reordered copy. Then share the result anywhere or save it straight to Files — named after your original, so it's easy to find.
