Choose a PDF and cut it into separate files: every page on its own, every few pages, or wherever you tap. If your form has a KB limit, each file is made to fit. It is made on your device, so your PDF is never uploaded.
Pick a PDF from your phone or computer. Up to 25 pages are opened. A PDF with a password asks for it.
Tap Every page, Every 2 pages or another button, or tap Split here between two pages. Each file is shown as File 1, File 2 and so on, with its pages.
Good quality has no limit. Tap Under 100 KB, 200 KB or another size if your form has a limit, or type your own number of KB.
Tap Split my PDF. Save each file on its own, or all of them in one ZIP. Take out or turn pages before you split, if you need to.
Tap between two pages to start a new file there, and tap again to join them back. Every file is shown with its pages before you split.
One tap makes a file of every page, or of every 2, 3 or 5 pages. Names such as report-pages-1-3.pdf keep them in order.
Each file is made to fit under the limit you choose, and you see the size of each one before you save.
The pages are copied as they are when the file is small enough, so text stays text. They are made lighter only as much as a limit needs.
Save any file on its own, save them all in one ZIP, or send them from the Share menu of your phone.
The PDF is opened and cut in your browser, on your device. Nothing is sent to a server. A PDF with a password asks for it, and the new files have none.
