Split PDF without uploading
Cut a PDF into pieces with the file never leaving your machine — and rather than ask you to believe that, this page tells you how to watch it be true.

Your browser would not let the file travel between pages (private mode does this) — open Split PDF and drop it there instead.
What happens to your file
It runs in this tab.
Your own browser does the work. Open the Network tab and watch it run: no request carries your file, and there is nothing on a server of ours to delete afterwards.
See every page first and cut between them, instead of typing ranges blind.
- No watermark The result is your file, unmarked. There is no paid tier that removes something we put there.
- No account Split PDF is exactly the same signed in or out. There is nothing to sign up for.
- No ads, no waiting No banners, no upsell pop-up, and no invented thirty-second queue standing between you and your download.
- Nothing to install It is a web page. The same one works on a phone: no app, no extension, no browser plugin.
- What it reads PDF. Anything it cannot read is turned down with a reason on screen, not a silent nothing.

How the workspace works
It plays on its own. Tap a step to hold it there.

The test that needs no tools at all
Watching the Network tab, as the panel above suggests, is the exact check. Here is the one that needs nothing but the machine in front of you: load this page, turn off your wi-fi, and then do the split. It works.
That is the whole claim, demonstrated rather than asserted. The file was never going anywhere, so taking the connection away changes nothing about the work.
What actually runs
The browser hands the page the file you picked, which is what a file input is for. It is read and rebuilt with pdf-lib inside a Web Worker — a second thread in the same tab — so a three-hundred-page document does not freeze the page while it works.
The pieces are produced in that worker and handed straight back as downloads. At no point does a copy exist anywhere but in the tab, and closing the tab is the end of it.
What the page does send, since “nothing” would be untrue
The page loads a view counter, as most sites do, and it records that a page was opened and how far somebody got — opened, started, finished, downloaded. That is how we know which tools are worth the work.
It cannot describe your file, and that is enforced rather than merely intended: the properties an event may carry are a closed list of four — which tool, which surface, device or server, which plan — each matched against a pattern. There is no key a file name, a size or a page count could travel in, and the pattern for the tool name has to begin with a letter specifically so that a number of bytes cannot pose as one. The privacy page spells this out.
What working this way costs you
The whole document sits in the tab’s memory while it is worked on, which means the ceiling is your device rather than our pricing. A very large PDF on an old phone can run out of memory where a server would have chewed through it.
That is the trade, and it is the right way round for most documents and the wrong way round for a few. It is worth knowing which side of it you are on before you drop in something enormous.
Nine questions
Questions
Does it work with no internet?
The splitting does; the first load does not. There is no offline copy of the site, so the page has to be fetched once. After that the connection plays no part in the work, which is why pulling the wi-fi and splitting anyway is a fair test of the claim.
Is there a file size limit?
None that we impose. The limit is what your device can hold in one tab, so it moves with the machine rather than with a plan. Large documents are fine on a laptop; a very large one on an old phone may not be.
How do I know the pieces are right before I take them?
The cuts are drawn against the actual document, and every piece is named on screen before any of them is produced. What you are about to download is shown to you rather than described.
Is Split PDF free?
Yes. Free, with no watermark, no account and no daily cap. It runs entirely in your browser, so there is nothing to meter.
Does my file get uploaded?
No. Everything happens in this browser tab, so the file never leaves your device. You can keep the Network tab open while it runs: no request carries your file.
Do I need an account?
No. This tool is exactly the same signed in or out.
Will it add a watermark?
No. The result is your file, unmarked. There is no paid tier that removes something we put there, because we do not put anything there.
Does it work on a phone?
Yes. It is the same web page, laid out for a small screen. Nothing to install, no app and no browser extension.
Are there ads, or a queue before the download?
No. No banners, no upsell pop-up, and no invented delay. When the job is done the file is ready.
