How to split a PDF into separate files
- Open the file first
Use the reader to find the page numbers you actually want. Guessing costs more time than checking.
- Pick a split mode
Ranges for a document with known sections, cut points for one or two joins, fixed chunks for something long and uniform.
- Write the numbers
Page numbers are counted from the first page of the file, not from any number printed on the page itself. These often differ by a cover page or two.
- Split and download
One output file comes back as a PDF; several arrive as a ZIP with each part named in order.
Why this matters for exam and study documents
Many boards publish a question paper and its mark scheme as one combined PDF. Splitting at the page where the mark scheme starts gives you a paper you can sit properly, without the answers one scroll away.
What is kept, what changes, and what this will not do
Page operations copy content rather than re-rendering it, so nothing here costs quality. What changes is which pages exist and where they sit - and the numbering printed on them stops matching.
Kept
- Page content, fonts and images exactly as they were
- Page orientation and paper size
- The relative order of pages within each part
Changed
- The document outline is not carried into the parts
- Internal links that pointed to a page now in a different file stop resolving
- Each part is a new document with its own metadata
Limits
- Page numbers refer to the file's own sequence, starting at 1.
- Cut points must fall inside the document.
Questions and answers
What is the difference between splitting and extracting?
Splitting divides the whole document into parts that together account for every page. Extracting pulls out a selection and discards the rest. If you want pages 3, 7 and 12 in one new file, that is extraction.
How do I find the page a mark scheme starts on?
Open the file in the reader and search for a phrase that only appears in the mark scheme, such as 'Mark Scheme' or 'Accept any of'. The reader reports the page number of each match.
Why does my split come back as a ZIP?
Because a split that produces more than one document cannot be delivered as a single PDF. The ZIP keeps the parts named and ordered.
