Split a PDF into separate files

Three ways to split

Custom ranges is the most flexible: type something like 1-3, 4-10, 11 and you get three files with exactly those pages. Fixed size cuts the document into equal chunks — handy for uploading a 60-page scan to a portal that accepts at most 20 pages per file. Every page produces one PDF per page, which is what you want when each page is a separate invoice or certificate.

Writing page ranges

Use a hyphen for a run of pages (5-8), commas to separate parts, and an open end to mean “to the last page” (12-). Ranges may overlap if you need the same page in two outputs. Pages are counted as printed in the PDF, starting at 1, regardless of the page labels shown in some viewers.

Ranges into one file

Tick “Merge all ranges into one PDF” if you only want to keep certain parts of the document in one file. For example, 1-2, 9-12 gives a single six-page PDF. That is the same idea as Extract pages, but driven by typed ranges instead of clicking thumbnails.

File names

Each part is named after the original file plus the pages it contains, such as report_pages-4-10.pdf, so the parts sort correctly when you unzip them.
