Split PDF Online

What this tool does

Split PDF Online lets you pull a continuous range of pages out of a PDF and save them as a brand-new file. Drop in a document, tell it the first and last page you want, and it builds a fresh PDF containing just that range. The original file on your device is never modified, so you can split the same document as many times as you like.

This is the fastest way to turn one big PDF into a smaller, more shareable section — a single chapter, the pages you need to email, or one form from a longer packet.

How to use the PDF splitter

1. Click Choose a PDF file and select the document you want to split.
2. The tool instantly reads the file and shows you the total page count.
3. Enter the From page and To page for the range you want to keep (page numbers are 1-based, so the first page is 1).
4. Click Split & download. A download link appears with your new PDF, named with the page range for easy reference.

If you type the pages in the wrong order, the tool quietly swaps them, and if the to page is past the end of the document it uses the last page instead. That means you always get a usable file rather than an error.

Is it private and safe?

Yes — completely. This tool runs 100% in your browser. When you select a PDF, it is read into memory on your own device with file.arrayBuffer(), processed by the open-source pdf-lib library, and offered back to you as a download. Nothing is ever uploaded to a server. There is no account, no queue, and no copy of your file left anywhere online.

That makes it genuinely safe for sensitive material — contracts, medical records, bank statements, legal filings — where uploading to a random web service would be a real privacy risk. You can even disconnect from the internet after the page loads and the splitter will still work.

Tips for splitting PDFs

• Need a single page? Set both from and to to the same number — for example, from 7 to 7 extracts just page 7.
• Splitting into multiple parts? Run the tool more than once with different ranges (for example 1–10, then 11–20). Each run downloads a separate PDF.
• Want non-adjacent pages like 1, 4 and 9? Use the companion PDF Page Extractor, which accepts a comma-separated list and ranges together.
• Keep the originals. Because the split never alters your source file, there’s no risk in experimenting with different ranges until you get exactly what you need.

Why split a PDF in the browser?

Browser-based splitting is faster than most upload-and-wait websites because there is no round trip to a server — the work happens on your machine the instant you click. It also sidesteps the file-size and daily-conversion limits that free online converters often impose. For anyone handling documents they would rather not share with a third party, an in-browser PDF splitter is simply the smarter, more private choice.
