About PDF Splitter

PDF Splitter lets you divide a PDF document into smaller files, entirely inside your browser. It uses pdf-lib for writing output PDFs and PDF.js for rendering page thumbnails. Nothing is uploaded to any server. Three split modes are available: extract a page range, split into equal-sized chunks, or hand-pick individual pages.

How to Use

Upload your PDF using the upload zone or drag & drop.
Choose a split mode from the tabs: Extract Range, Split Every N Pages, or Pick Pages.
Extract Range: Enter the start and end page numbers and click Extract — downloads one PDF with those pages.
Split Every N Pages: Enter the chunk size (e.g., 5 for 5 pages per file) and click Split — multiple PDFs download sequentially.
Pick Pages: Click thumbnails to select specific pages, then click Extract Selected — downloads them as a single PDF.

How It Works

PDF Splitter uses pdf-lib to create and save the output PDFs, and PDF.js to render page thumbnails for the Pick Pages mode. All processing runs locally in your browser — no files are sent to any server.

Frequently Asked Questions

Are my files uploaded to a server?: No. Both pdf-lib and PDF.js operate entirely in your browser. Your PDF never leaves your device.
What's the difference between the three split modes?: Extract Range gives you one continuous block of pages as a single PDF. Split Every N divides the whole document into equal-sized chunks. Pick Pages lets you choose any combination of individual pages, which are merged into one PDF.
How are output files named?: Extract Range saves as pages-[from]-[to].pdf. Split Every N saves as part-1.pdf, part-2.pdf, etc. Pick Pages saves as selected-pages.pdf.
Can it handle large PDFs?: Yes, but very large PDFs (100+ pages or large file sizes) may take a moment to load and render thumbnails. The splitting itself is fast once the file is loaded.
Will the output PDFs preserve all formatting?: Yes — the pages are copied exactly from the source PDF. Text, images, fonts, and layout are all preserved.
