Split PDF

Split a PDF in your browser for free — no upload, no account, no page limits. Carve one document into separate files three ways: each page on its own, by custom page ranges like 1-3, 4-8, 9-, or in fixed chunks of every N pages. One range gives you a single PDF; several come back as a tidy zip.

Split PDF — how it works

Open your PDF. Drag a PDF onto the page or click Choose a PDF; it loads instantly and shows the page count without going anywhere.
Pick how to split. Choose each page to its own file, type custom ranges (comma-separated groups such as 1-3, 4-8, 9-), or set a pages-per-file number for even chunks.
Split and download. Hit Split and download — one group saves as a single PDF, several save as a zip of numbered parts, generated right in your browser.

Your files never leave your browser

Your PDF is split entirely on your own machine. When you drop a file in, it is read into memory and processed by a Web Worker running in your browser — there is no server step and no upload, so the document never travels across the network. Because the work is local, the size of your file is bound only by your device's memory, not an upload cap. The site is open source and ships a strict Content Security Policy that blocks outside connections, so you can verify the claim. Once the split files have downloaded, refresh or close the tab and nothing lingers — no copies are kept anywhere but your own downloads folder. Read the privacy policy →

Frequently asked questions

Is my PDF uploaded to a server when I split it?

No. The split happens locally in a browser Web Worker — your file is read into memory on your device and never sent anywhere. There is no upload and no server processing.

Is it free, and do I need an account?

Yes, it is completely free with no account, sign-up, or watermark. Split as many PDFs as you like.

Are there file-size or page limits?

There are no artificial caps. Since everything runs in your browser, the only real limit is your device's available memory, so very large PDFs depend on your machine rather than a server quota.

Does it work offline, on Mac, or on my phone?

It runs in any modern browser on Windows, Mac, Linux, ChromeOS, and mobile, and once the page has loaded it keeps working offline since nothing is uploaded.

How do the output files come out, and can it split encrypted PDFs?

A single range saves as one PDF; multiple ranges download as a zip of numbered parts. Password-protected or damaged PDFs can't be read here — use the DocLab desktop app for those.
