Are my files uploaded to a server?

No. The file is read into your browser's memory and processed by your own device. You can confirm this in your browser's network inspector — no request carrying your document is made.

How long are my files kept?

They are never stored anywhere to begin with. The file exists only in the memory of the browser tab, and it is released the moment you close the tab, reload the page, or press start over.

How do I write a page range?

Use commas between entries and hyphens inside a range, like 1-3, 7, 9-12. Spaces are ignored. Pages come out in the order you list them, and a page listed twice only appears once.

What happens if I ask for a page that does not exist?

You get a clear message naming the page and telling you how many pages the document actually has, before any processing starts. Nothing is downloaded and nothing is lost.

Does splitting change the pages themselves?

No. Each output page is copied from the original at the object level, so text, fonts, images and page dimensions are exactly as they were.

Can I download all the split files at once?

Yes. The results view has a download-all button that saves every file in turn. Your browser may ask once for permission to download multiple files — allow it and the rest follow automatically.

Is the original file changed?

Never. The tool reads the file you select and builds new documents from it. The file on your device is exactly as it was when you started.

Secure Split PDF

Break one PDF into separate files, or pull out just the pages you need.

Drop your PDF file here

or browse your device

A single PDF file, up to 100 MB. Files are processed on this device.

The most secure way to handle a confidential document is not to send it anywhere. This tool is built that way: your PDF file is read into the browser tab in front of you, processed there by your own device, and never transmitted.

That is a meaningfully different security model from "we encrypt uploads and delete files after an hour". Both are reasonable, but one requires you to trust a retention policy you cannot inspect, and the other removes the need to trust anything, because there is no server-side copy to protect in the first place.

You can verify this yourself. Open your browser's developer tools, switch to the network tab, and run the tool. You will see the page and its scripts load, and then nothing further — no request carrying your document to any server.

Splitting a PDF means one of two quite different things depending on the day. Sometimes you want every page as its own file — useful when a scanner has handed you a fifty-page batch that is really fifty separate documents. Other times you want to pull out pages seven through twelve and nothing else. This tool does both.

Choose one PDF per page and you get a numbered set of single-page files, each named after the original. Choose a page range and you get one new PDF containing exactly the pages you listed, in the order you listed them. Either way the original file on your device is left completely untouched.

How to split a PDF file

Add your PDF
Drop a single PDF onto the upload area, or press it to browse your device.
Choose how to split
Pick one PDF per page to burst the whole document, or extract a page range to pull out a specific section.
Enter the pages you want
If you chose to extract a range, type it as a list — 1-3, 7, 9-12. Page numbers start at 1 and each page appears only once in the output.
Split the file
Press Split PDF. Progress is shown page by page for long documents.
Download the pieces
A single extracted range downloads as one file. A full burst gives you a list where you can grab pages individually or download the whole set.

Why use this split pdf tool

No upload at any point

Your document is read from your device into browser memory and processed there. It is never transmitted to any server.

Nothing is retained

There is no server-side copy to store, so there is no retention window, no deletion job and no backup holding your file.

Independently verifiable

Open your browser's network inspector and watch. No request carrying your file will appear, because none is made.

Two modes, one tool

Burst a document into single pages, or extract a specific range into one new file, without switching to a different page.

Readable page ranges

Write ranges the way you would say them out loud — 1-3, 7, 9-12 — and the tool validates them against the real page count before it does anything.

Predictable filenames

Output files are named after the source document with the page number appended, so a folder full of them still makes sense a month later.

Features

Page-by-page burstTurn an N-page PDF into N separate single-page PDFs.
Range extractionPull out any combination of pages and ranges into one new document.
Range validationImpossible ranges are reported before processing rather than failing halfway.
Cancel any timeLong documents show live progress and can be stopped mid-run.
Original untouchedThe file you selected is only ever read, never modified.

When people use this

Separating a scan batch

A stack fed through a document feeder often comes back as one PDF containing many unrelated documents. Burst it into pages, then keep only what you need.

Sending one chapter

Extract pages 42 to 58 of a long report so a colleague receives only the section that concerns them rather than the whole thing.

Removing pages before sharing

Extract everything except the pages you would rather not circulate, and share the new file instead of the original.

Preparing pages for signature

Pull the signature page out on its own, sign it, and merge it back into the document afterwards.

How to verify the security claim yourself

Security claims are worth exactly as much as your ability to check them, so here is how to check this one. Press F12 to open developer tools, or right-click the page and choose Inspect. Select the Network tab and clear whatever is listed.

Now add your file and run the tool. Watch the network tab throughout. You will see requests for the page's own JavaScript — including the PDF libraries, which are loaded on demand the first time you use a tool — and then nothing. No POST request, no upload, no transfer of your document. The processing happens entirely between your file and your device's memory.

You can go further and disconnect from the network entirely once the page has loaded. Every tool on this site except PDF to Word will continue to work perfectly with no connection at all, which is only possible because nothing is being sent anywhere.

The one deliberate exception is the PDF to Word converter, which needs server-side layout analysis. That tool says so plainly on its own page rather than being quietly grouped in with the rest.

How splitting works

The source PDF is parsed once with pdf-lib and its page count is read. For a burst, the tool creates a fresh single-page document for each page index and copies that one page into it. For a range extraction, it creates a single document and copies the pages you listed into it in that order.

Because pages are copied as objects rather than re-rendered, the output is byte-for-byte faithful to the input in terms of content. A page that was 2 MB of scanned image in the original is still that image in the split file — splitting is not a compression step, and a 50-page document split into 50 files will add up to roughly the size of the original plus a small amount of per-file structural overhead.

Privacy

Your files are not uploaded. When you add a PDF file, your browser reads it from your device into the memory of the tab you are looking at, and the split pdf operation runs there using your own processor. Nothing is transmitted to any server at any point.

That means there is no file for anyone to store, no retention policy to trust, and no deletion schedule to take on faith. The document exists only in the memory of an open browser tab, and it is released the moment you close it, reload the page, or press start over.

The site uses standard anonymous analytics to count page views and how often each tool is used. Those events record which tool ran and whether it succeeded — never a file name, never file contents, and never anything that could identify a document or the person processing it.

No account is required, so no personal information is collected. There is no profile, no history and nothing tied to an identity, because no identity was ever created.

Security

The strongest security property this tool has is structural: your file never travels anywhere, so there is no transmission to intercept and no server-side copy to breach. This is not a policy that could change — it is a consequence of where the code runs.

You can verify it in about thirty seconds. Open your browser's developer tools with F12, select the Network tab, and use the tool. You will see the page's scripts load — including the PDF libraries, which are fetched on demand the first time a tool runs — and then nothing further. No request carrying your document is ever made.

For a stronger test, disconnect from the network once the page has loaded. The tool will keep working exactly as before, which is only possible because nothing is being sent.

Uploaded files are validated in the browser before anything runs: the extension must match what the tool accepts, the file must not be empty, and it must be within the size limit. Malformed documents produce a clear error and a retry option rather than a silent failure.

What this tool does not do

Being clear about limits is more useful than a feature list that quietly omits them. Splitting does not reduce file size, and document-level features such as bookmarks and form fields are not carried into the individual pieces.

If you need capabilities beyond that — redaction, PDF/A conformance, OCR, or scripted batch processing across thousands of documents — dedicated desktop software genuinely earns its licence fee, and this is not trying to replace it. For the specific job of producing a split PDF files, everything you need is on this page.
