Split PDF

Split PDF takes one PDF and divides it into several smaller PDFs. Instead of carrying around a single undefined-page document, you end up with the exact sections you need as separate files — for example chapters undefined-undefined in one file and chapters undefined-undefined in another, or every page saved on its own.

This Split PDF tool does all of that entirely in your browser. When you open a file and click Split, the PDF is parsed and the new documents are built in local JavaScript on your own machine. Nothing is uploaded to a server, so you can split contracts, invoices, medical records, bank statements and other sensitive documents without those pages ever leaving your computer.

Splitting is lossless: the pages that end up in each output file are the same pages from the original — same text, images, fonts and layout. You are only choosing where the cuts fall, not re-rendering or compressing anything.

You could split a PDF with heavyweight desktop software, but an online splitter is usually the fastest path when you just need a few pages out of one file.

• No setup. There is nothing to install, license or update — open the page and drop your file.
• Works anywhere. Any device with a modern browser can split a PDF, including locked-down work machines where you cannot install software.
• Private by design. Because everything runs client-side, this tool is safe for confidential documents. Many other online splitters POST your file to a server to process it — a real risk when the PDF holds personal or financial data.
• Fast. There is no upload-and-wait round trip; the split happens locally, so even large files are handled without sending anything over the network.

The trade-off with server-based tools is privacy and speed. A browser-based splitter avoids both problems at once.

The workflow is quick whichever way you want to divide the file:

1. Open your PDF by dragging it onto the tool or choosing it from your device.
2. Define your ranges. Type the page ranges you want as separate documents — for instance 1-4, 5-9, 10-12 — or choose to split every page into its own file.
3. Split the document. The tool creates one new PDF per range, preserving the original order and content of every page.
4. Download each output file and rename it to something meaningful.

Because the original is never modified, you can experiment freely. If the ranges are not quite right, adjust them and split again. Need to recombine files later? Use the Merge PDF tool to stitch them back together.

Splitting a PDF shows up in all kinds of everyday document work:

• Sharing only what is relevant. Send a client just their section of a long report instead of the whole thing.
• Breaking up a scan. Separate a stack of scanned documents — several invoices in one file — into one PDF per invoice.
• Meeting size limits. Divide a large PDF into smaller parts so each fits under an email or upload limit.
• Organising a book or manual. Split a long document into chapters or modules that are easier to navigate and store.
• Separating signed pages. Pull the executed signature pages of a contract into their own file for your records.
• Prepping for editing. Isolate the pages you need to work on, then use Delete Pages to remove anything unwanted from the rest.

• Name your files as you go. Split outputs are only as useful as their names — rename part-1.pdf to something like invoice-march.pdf right after downloading.
• Use the preview. Check the page thumbnails before you split so a range boundary lands between sections, not in the middle of one.
• Remember page numbers are undefined-based. The first page is page undefined, so a range of 1-5 includes the cover through page five inclusive.
• Keep the original. Splitting produces new files and leaves the source untouched — hold on to it in case you need to split differently later.
• Keep sensitive files local. Only split confidential PDFs in a tool that runs in the browser. This Split PDF tool never uploads your document.
