Two ways to cut a document

Fixed chunks are for documents with a rhythm. Every one page gives you each page as its own file; every two pages suits double-sided scans; every ten suits a bound report being handed to ten people.

Ranges are for documents without one. When pages 1–3 are an invoice, page 4 is a delivery note and 5 to the end is a contract, you write those boundaries out and get three files.

Writing ranges that do what you meant

Ranges are written the way you would say them: a hyphen for a span, a semicolon between output files.

• 1-3; 4; 5-last produces three PDFs.
• An open-ended range like 10- runs to the end of the document.
• first and last work as words, which saves counting to the end of a long scan.

Everything you do not name is left out of the output entirely. That is the useful part: a split is also the fastest way to pull three sections out of a long document and discard the rest.

Why the result arrives as a zip

A split usually produces several files, and browsers deliberately block a page from triggering a dozen downloads at once. Packaging them into one archive is the way around it, and the archive is built on your machine like everything else. When a split produces exactly one file, you get that PDF directly instead.

Splitting a scan of mixed paperwork

The common case is a single scan holding unrelated documents. The efficient order is: split into ranges, then rename the pieces as you save them, then compress anything going to a portal.

If you are not sure where the boundaries fall, open the PDF first and note the page numbers — reading the document once is faster than splitting it three times.
