Split PDF
Break a PDF into separate documents — every page on its own, or by the ranges you type.

Produces one PDF per page: as many files as there are pages.
3 · Split and download

The split documents appear here.
Splitting happens in this browser. The PDF is not uploaded, stored or logged.
Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.
How to use it
- Choose a PDF. Its page count is read from the file before you decide anything.
- Pick “Every page separately” for one document per page, or “By ranges” and type the pieces, such as 1-3,4-6.
- Check the planned output — how many documents, and how many pages between them.
- Press Split, then download the ZIP or the single document if there is only one.
Limits worth knowing
- A split produces several documents. If you want some pages kept together in one file, that is extracting, not splitting — the two tools are separate so the difference cannot be lost on you.
- Up to 200 output documents from one split, and 200 pages across the input. Both are memory ceilings: each output is a complete PDF built in your browser tab.
- Each output is rewritten rather than sliced out of the original, so page content and order survive but document-level parts do not: no table of contents, no form fields, no embedded attachments, and no shared font subsets carried across untouched.
- Password-protected PDFs are refused rather than opened by force. Remove the protection first.
- Filenames carry the page numbers inside each document — a two-piece file is named pages-1-2…, a single page page-3… — followed by the source name, and made unique, so two outputs can never overwrite each other inside the archive.
What the ranges mean
Every range you type becomes its own PDF, in the order you typed them. `1-3,4-6` is two documents of three pages each; `1,2,3` is three documents of one page. A page may appear in two ranges if you ask for it, and then it appears in two files.
Ranges are counted from 1, the way a PDF reader numbers pages, not from 0 the way the file stores them. A range that counts backwards is rejected with the ascending form suggested, because guessing which of the two you meant is how the wrong pages get sent somewhere.
If a range reaches past the last page, the split is refused and the message names the page it stopped at and how many the document actually has.
Why the output is a ZIP
A browser downloads one file at a time, and prompting for twenty separate saves is not a usable tool. So several documents are packaged into one archive, built in the browser after the PDFs are written.
The archive is loaded only when a split actually produces more than one document, which means a single-output split does not pay for it.
Every document is listed with its page count and size after the run, and each one is re-opened to confirm it parses. If the archive fails to build, the list is still shown rather than the work being lost silently.
Choosing between split and extract
Split answers “I have one document that should be several.” Extract answers “I have one document and want a subset of it as one document.” The outputs are different shapes, which is why they are different pages.
If you want chapters as separate files, split by range. If you want the pages you need in one attachment to email, extract them.
