How to split a PDF
Almost every form that asks for a PDF wants a few specific pages, not the forty-page document those pages came in. Splitting takes the pages you name and writes them out as their own file. It runs on your own device — the PDF is never sent anywhere.
Steps
Open the Split tool
Go to Split PDF and choose your file. The tool reads how many pages it has right away and shows you the number, so you know what you are working against. If the file cannot be read at all, it says so at this point rather than after you press the button.
See every page before you choose
Every page shows as its own thumbnail, so you are picking from what the document actually looks like rather than guessing at numbers. Tap a page to select it, or click and drag across several to select a run in one go — the same page grid the rotate tool uses, so if you have used that one this already looks familiar.
Pick pages, split points, or a page count
Pulling out a set of pages works from the grid or from a typed range like 1-3, 7, 10-12 — the two stay in sync, so selecting on the grid updates the text and typing updates the grid. To cut the whole document into several files instead, click the scissors between two pages to mark a cut, as many times as you need; each page picks up a colour showing which output file it will land in. Splitting every few pages skips selecting anything — just say how many pages each file should hold.
Check the summary, then split
A line above the grid says exactly what pressing the button will produce — how many files, and which pages land in each — before it happens. A range comes back as one file named after the original; split points or an every-few-pages split come back as a list of links, one per file. Open what you downloaded before you send it — checking takes five seconds and catches an off-by-one straight away.
One thing to check if your PDF is a fillable form: the pages come across, but the wiring that makes a form a form lives at document level and does not follow the pages into the new file, so a split copy may no longer be fillable. Split a copy, open the result, and keep the original.
Common questions
Does splitting lower the quality?
No. The pages are copied across with their own fonts, vectors and images intact — nothing is re-rendered and nothing becomes a picture. Text in the split file stays selectable and searchable exactly as it was.
Can I reorder the pages while I split?
Yes. The order you type is the order you get. Typing 3, 1, 2 produces a document with those pages in that sequence, so a small reorder does not need the editor.
Will splitting make the file smaller?
Usually, and often by far more than compressing would. Five pages taken out of a fifty-page document is a fraction of the size, which is why splitting is the better answer when a form rejects your file for being too large.
Why do I get separate links instead of a ZIP?
Because a ZIP would mean shipping an archiver to every visitor, including everyone who never splits anything. For the handful of pages most people pull out, separate links cost nothing and work everywhere.
Is my file uploaded to a server?
No. The split runs in your browser tab. You can check it yourself: open your browser network tab, split a file, and watch that nothing leaves.
