About PDF Split

PDF Split is a free, browser-based tool that extracts specific pages or page ranges from a PDF document and saves them as separate PDF files. Powered by the pdf-lib library, every operation runs entirely inside your browser without transmitting your files to any server, keeping confidential documents fully private.

The tool serves students who need individual chapters from a large textbook PDF, professionals who must share specific contract clauses without exposing the full document, and designers who want to isolate certain pages for review. Both individual page extraction (one output file per selected page) and contiguous range extraction (one output file covering pages N through M) are supported in a single interface.

When you load a PDF, the tool reads the file with pdf-lib, counts total pages, and renders a clickable grid of page-number buttons. In individual mode, each selected page index is extracted into its own new PDFDocument with copyPages() and addPage(). In range mode, all pages between the start and end numbers are copied into one document. The resulting files are named with the source filename and page reference, then offered as individual or bulk downloads.

Key Features

  • Two split modes: extract each page as an individual file, or extract a contiguous page range as one file
  • Visual page-number selector grid for individual mode — click to toggle any page on or off
  • Select all / deselect all buttons for rapid page selection in large documents
  • Numeric range inputs for precise start and end page selection in range mode
  • Output files are named automatically as filename_page1.pdf or filename_pages3-7.pdf
  • 100% client-side processing via pdf-lib — your PDF never leaves your browser
  • Bulk download button to save all split pages at once when extracting multiple pages
  • Supports PDF files up to 50 MB with instant in-browser processing

Frequently Asked Questions

What is the difference between individual mode and range mode?

Individual mode creates one separate PDF file for each page you select, so selecting pages 1, 3, and 5 gives you three files. Range mode creates a single PDF containing all pages between a start number and an end number, so range 3-7 produces one file with five pages.

Can I extract non-consecutive pages into a single file?

In the current tool, individual mode creates one file per selected page. To combine non-consecutive pages into one file, extract them individually and then use the PDF Merge tool to combine the resulting files in your desired order.

Will the split pages retain their original formatting, images, and fonts?

Yes. pdf-lib copies each page stream directly from the source PDF without re-rendering. All text, fonts, images, vector graphics, and page dimensions remain exactly as in the original document.

How do I split a PDF into equal parts?

Use range mode with equal-sized intervals. For example, to split a 12-page PDF into three 4-page sections, run range 1-4, then 5-8, then 9-12. Each run produces one output file covering that range.

Is there a page limit for how many pages I can extract?

No. You can select any number of pages from a PDF regardless of total page count, as long as the source file is under 50 MB. Processing time scales with the number of pages and the file size.

Does my PDF get uploaded to a server during splitting?

No. The entire split operation — loading the file, parsing pages, creating output PDFs — happens inside your browser using JavaScript. No network requests are made and no data is sent to any external server.

What file format are the extracted pages saved in?

All extracted pages are saved as standard PDF files (.pdf). The output files are valid, self-contained PDFs that can be opened in any PDF viewer, shared by email, or further processed with other PDF tools.

Can I split a scanned or image-based PDF?

Yes. The tool copies page streams directly and does not need to interpret the content. Even if a page is just an embedded image (like a scanned document), it will be extracted faithfully into its own PDF file without any quality loss.
