Split PDF

Split PDF is a PDF tool that extracts a subset of pages from a PDF into a new document. It accepts mixed page-range syntax like 1-3, 5, 7-9, offers an inverse "remove pages" mode, and outputs a new PDF instantly. The tool runs in your browser.

How to split a PDF

  1. Drop your PDF onto the upload area or click to browse.
  2. Enter the page range you want to extract, for example, "1-3, 5, 7-9".
  3. Click "Extract pages" to generate a new PDF containing only those pages.
  4. Download the extracted PDF.

Common uses

  • Extracting specific pages from a large report to share only the relevant sections, then merge PDFs to combine the extracted parts with other documents
  • Removing pages you do not need before sharing a document
  • Splitting a scanned document into individual pages or chapters, use PDF to image to convert individual pages to JPG or PNG

Technical specification

  • Algorithm or formula: Parses the page-range string into a sorted, deduplicated set of 1-based page indexes. pdf-lib's copyPages copies the selected pages into a fresh PDFDocument in their original order.
  • Browser API or library: pdf-lib for PDF write; standard File and Blob APIs for input and download.
  • Input limits: PDF up to 100 MB. Page-range syntax accepts single numbers, dash ranges, and comma separators (e.g., 1, 3-5, 8).
  • Output: New PDF (application/pdf) containing only the selected pages (or the unselected pages in remove mode), downloaded via Blob URL.
  • Known limitations: Internal hyperlinks pointing to pages not in the output become dangling. Bookmarks referring to dropped pages may be lost.

Frequently asked questions

Is my PDF uploaded to a server?
No. All processing is done in your browser using pdf-lib.
Can I split a PDF into individual pages?
Yes. Enter each page number separated by commas to extract them individually, or use a range like 1-10.
Can I remove specific pages instead of extracting them?
Yes. Use the "Remove pages" mode to specify which pages to delete. The tool produces a PDF with those pages removed.
Is there a page count limit?
There is no hard limit. The tool processes entirely in browser memory. Very large PDFs may take a few seconds to load and process.
