Split PDF

Split, Extract, or Organize — pick the right verb

These three tools sound interchangeable and aren't. Split produces many files from one: a 40-page board pack becomes one PDF per director, or a scanned book becomes a folder of chapters. Extract PDF Pages does the opposite — it pulls your chosen pages into a single new document, so 'pages 3, 8 and 12' come out as one three-page file, not three. Organize PDF keeps everything in one document but lets you reorder, rotate and delete pages. The quick test: if your answer to 'how many files do I want out?' is 'more than one', you want Split.

Because Split can emit dozens of files at once, the output is bundled as a single ZIP rather than firing off twenty separate downloads your browser would block. Unzip it and the files are named by their source range or page number so the order is never ambiguous.

The three split modes, and when each one earns its keep

• Range — type something like '1-3, 5, 7-9' and each comma-separated entry becomes its own file. This is the mode for uneven, meaningful chunks: cover letter, then the report body, then the appendix, cut at the boundaries you actually care about.
• Every-N — split every N pages into a new file. Perfect for regular structure: a 100-page statement that's 4 pages per account splits cleanly into 25 files with N=4, no manual range typing.
• One-per-page (burst) — every page becomes its own PDF. Use it when each page is a standalone artefact: a sheet of pre-printed invoices, a batch of certificates, or scanned forms you'll route to different people.
• Not sure which? Range is the safest default — it's the only mode that respects boundaries you define rather than a fixed count.

Mistakes that produce the wrong files

The classic error is off-by-one page numbering. PDF page numbers are physical positions, not the printed folios on the page — if your document has a separate cover and a roman-numeral preface, 'page 1' to the tool is the cover sheet, not the page printed '1'. Open the document and count tiles, don't trust the printed numbers.

The second is reaching for Split when you wanted one file. If a colleague asks for 'just the signature pages', bursting the whole document hands them a ZIP of 60 files to dig through. Extract PDF Pages gives them a single tidy PDF instead. And if the source is password-protected, clear it with Unlock PDF first — an encrypted PDF can't be read, let alone split.
