A practical guide

Break a big file into manageable pieces.

  1. Choose one PDF and check its page count.
  2. Pick separate pages, custom groups or a number of pages per part.
  3. Split, open the ZIP and check each PDF before using it.

Try this example

A 12-page class packet can be split into chunks of 3 pages, producing four PDFs. Choose custom groups instead if the sections end on different pages.

Before

  • 1-12: class packet

After

  • Pages 1-3
  • Pages 4-6
  • Pages 7-9
  • Pages 10-12
Three pages per part creates four files from twelve pages. Illustrative example.

Before you start: The download is a ZIP containing PDFs. Custom groups can omit pages; inspect the archive contents before sharing.

Combine selected parts later
What you get

Split a PDF into pages, custom page groups, equal-sized parts or chapters from bookmarks.

Limits and important details

Bookmark mode: 10 MiB input, 200 pages, 40 chapters, 200 outline items, depth 8, 40 MiB output. Local destinations only; top-level starts must be distinct and increasing. Nested bookmarks must stay within their chapter and are remapped; bookmark styles/open state and document metadata are not preserved. Forms, links, annotations, encryption and cross-chapter outlines are unsupported. Other modes: 200 files, 500 output pages, 60 MiB, no guaranteed bookmark/form preservation. Saving invalidates signatures. ZIP is not PDF input.

Example

Custom groups 1-2; 3-5; 6, 8 create three PDFs. In bookmark mode, chapter starts on pages 3 and 6 of an eight-page PDF produce front matter 1-2 and chapters 3-5 and 6-8. This uses bookmarks, not headings recognized from page text.
