A practical guide

Cut one file into the parts you need.

  1. Add the PDF and choose a split mode in the options.
  2. Enter the page groups or the number of pages per part.
  3. Run the task and open the ZIP to check each part.

Try this example

Split a 30-page report with the groups 1-10; 11-20; 21-30. The ZIP holds three PDFs of ten pages each, and the original stays as it was.

Input and expected output for this task. Illustrative example.

Before you start: Splitting by bookmarks follows the document outline, not headings found on the page. Saving may invalidate signatures.

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. Links within a chapter, comments and form fields are kept; links into another chapter are removed with a notice. Encryption and cross-chapter outlines are unsupported. Other modes: 200 files, 500 output pages, 60 MiB; links, bookmarks and form fields stay with their pages. 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.
