Split PDF

When You Only Need Part of the Document

A 200-page financial report. You need pages 45–52. Downloading and forwarding the whole thing is inefficient — and in some cases, you shouldn't share the parts you don't need.

Splitting lets you extract exactly the pages you want and produce a clean, smaller PDF containing only those pages. The source file stays untouched and never leaves your device.

Split Modes

By page range — specify a start and end page to extract a continuous section. Useful for pulling a chapter, a section, or a block of exhibits from a larger document.

Individual pages — extract a single page as its own file. Good for separating a signature page, a specific figure, or a cover sheet.

Every N pages — automatically divide a long document into equal chunks. A 60-page report becomes three 20-page files. Useful for distributing portions of a large document to different reviewers.

Custom selection — specify pages in any combination (e.g., "1, 3, 7–10, 15") and extract them as a single output file. Useful for compiling a highlights summary from a long document.

How Page Extraction Works Technically

PDFs aren't linear — they're hierarchical containers. Each page is an individual object in the PDF's structure, linked to its fonts, images, and rendering instructions. Splitting doesn't cut the file like a document editor would; it selectively copies the relevant page objects and assembles a new, complete, self-contained PDF with only those pages.

The tool uses pdf-lib running entirely in your browser's JavaScript engine. It reads your PDF's cross-reference table to locate each requested page, copies the associated objects, resolves any internal naming conflicts, and writes a new valid PDF file — all within your browser's memory. Your original document remains unchanged.

Real-World Scenarios

Contract management: A 40-page master agreement includes supplier-specific schedules as appendices. You need to send each supplier only their own appendix — not the entire contract. Split and distribute.

Academic work: A digitized textbook is one enormous file. Splitting into chapters dramatically improves reading performance on tablets and e-readers, and lets you annotate specific chapters without affecting the rest.

Legal submissions: Court exhibits are numbered individually. A lawyer extracting Exhibit 7 from a comprehensive case bundle to file separately can do it in seconds without rekeying...
