About PDFSplitter
A simple, free tool built because splitting a PDF shouldn't require uploading your files to a stranger's server.
Why We Built This
Most PDF tools online ask you to upload your file to their server. You click "Split PDF", your document travels across the internet to some server you know nothing about, gets processed, and then — hopefully — gets deleted. You just have to trust them.
For most people, that's fine. But what if your PDF contains a bank statement, a legal agreement, a medical record, or a confidential business document? Uploading that to a third-party server is a real privacy risk — one that most people don't think about until it's too late.
We built PDFSplitter because we wanted a tool that we could use ourselves without worrying. A tool that is genuinely private — not just claiming to be. The only way to guarantee that is to never receive your files in the first place.
So that's exactly what we did. PDFSplitter runs entirely in your browser. Your PDF is opened and processed locally on your device using JavaScript. Nothing is uploaded. Nothing is transmitted. Nothing is stored. We literally cannot see your files.
How It Works
When you upload a PDF on PDFSplitter, the file is read by your browser's JavaScript engine — the same engine that powers every website you visit. We use pdf-lib, an open-source JavaScript library, to read and split your PDF pages locally.
You can choose to split by file size — for example, break a 50MB PDF into parts no larger than 10MB each — or by page count — for example, 10 pages per part.
The split parts are then bundled into a ZIP file using JSZip, another open-source library, and downloaded directly to your device. The entire process happens without a single byte of your PDF leaving your computer.

What We Stand For
Privacy by design
We don't collect your files, we don't store them, and we don't want them. Privacy isn't a feature — it's the foundation.
Free forever
PDFSplitter is free and will stay free. No sign-up, no subscription, no usage limits. We built this because it's useful, not to monetize you.
Open and honest
Everything we claim about privacy is verifiable. The processing happens in your browser — you can open DevTools and see that no network requests are made when splitting.
Simple and fast
We deliberately keep the tool simple. No accounts, no settings pages, no dashboards. Upload, split, download — done.
Built by theFstack
PDFSplitter is built and maintained by theFstack, a full stack developer focused on building simple, useful tools for everyday problems.
This is one of several tools we're building under the same philosophy: keep it free, keep it private, keep it simple. No venture capital, no data harvesting, no dark patterns. Just tools that do what they say.
