How we handle your data

Split PDF

Create a ZIP of PDFs from individual pages, custom page groups, fixed-size chunks or top-level bookmarks. Group ranges use positions from page 1.

Synthetic example — review the operation settings before running.

A practical guide

Make the page boundaries explicit.

  1. Choose one PDF and confirm its page positions.
  2. Pick a split mode and set page groups, chunk size or bookmark chapters.
  3. Create the ZIP and verify each output file and its page range.

Try this example

In an eight-page document with chapter bookmarks starting at pages 3 and 6, bookmark mode produces front matter pages 1-2, chapter pages 3-5 and chapter pages 6-8.

Before

  • 1-2 Front matter
  • 3-5 Chapter 1
  • 6-8 Chapter 2

After

  • 3 PDFs in a ZIP
Top-level bookmark starts define chapter boundaries. Illustrative example.

Before you start: Bookmark mode reads top-level PDF bookmarks, not headings on the page. The download is a ZIP; check its chapter titles and ranges before distribution.

Reassemble chosen chapters
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.
