How to split PDF
- Choose the PDF you want to split. The tool reads how many pages it has.
- Pick a mode: extract specific pages, or cut the document into two parts.
- Press the button. The resulting file — or files — download to your device.
How it works
Splitting is the same operation as merging, run in reverse. Rather than removing pages from your original file, the tool creates a brand new empty PDF and copies only the pages you asked for into it. Your original file on disk is never modified, which means a mistake costs you nothing — you just run it again.
The two modes exist because people mean two different things by “split”. Extract takes a selection like 1-3, 7 and produces one new document containing exactly those pages, in that order. Split into two takes a cut point and gives you everything before it and everything after it as two separate files.
Page ranges accept a comma-separated mix of single pages and ranges: 2, 4-9, or 1, 5-7, 12. Numbering starts at 1 and matches what your PDF reader shows. If you type a page that does not exist, the tool says so and tells you how many pages the document actually has, instead of quietly giving you a shorter file than you expected.
All of this happens in the browser tab. The document is read from your disk into memory, processed by JavaScript running on your own processor, and written back out as a download. No copy of it is transmitted, stored, or retained anywhere.
A worked example
You have a 40-page tenancy agreement, lease.pdf. Your bank has asked only for the signature page and the payment schedule — pages 38 and 12–14. Sending the whole lease would disclose far more than they asked for.
Choose the file. The status line reads pages: 40. Leave the mode on Extract specific pages and type 12-14, 38 into the pages field.
Press Extract pages. You get lease-pages.pdf, four pages long, in the order 12, 13, 14, 38. Note that the tool sorts and de-duplicates your selection, so typing 38, 12-14 or even 12, 12-14, 38 produces exactly the same four-page result.
Now the other mode. Suppose instead you want the lease broken into “terms” and “appendices” at page 30. Switch to Split into two files, set the split point to 30, and you receive lease-part1.pdf with pages 1–30 and lease-part2.pdf with pages 31–40. Your browser may ask permission to download two files at once — that prompt is normal and is coming from the browser, not from this page.
If you only wanted to drop a few pages rather than keep a few, deleting pages is the shorter way round.
Questions
Can I divide a PDF into two separate files?
Choose Cut into two files and set where the divide falls. You get two documents, and the grid shows which pages land in each before you commit.
Is my PDF uploaded to a server?
No. The split runs entirely in your browser using JavaScript. This site has no backend to receive files. You can confirm it by opening the Network tab in your developer tools while you use the tool, or by disconnecting from the internet after the page has loaded.
What format should I use for the page selection?
Commas separate items and hyphens make ranges: 1-3, 7, 10-12. Pages are numbered from 1, exactly as your PDF reader displays them. Spaces are ignored, duplicates are removed, and the output is always in ascending page order.
Can I split one PDF into many separate single-page files?
Not in a single click, because browsers block long bursts of automatic downloads. To get individual pages, either run the extract mode once per page, or use the PDF to images tool if you want each page as a picture rather than as a PDF.
Will the original file be changed?
Never. The tool builds a new document from copies of the pages you selected. The file on your disk is only ever read, never written to.
Why did only one file download when I split into two?
Most browsers ask for permission before downloading multiple files from one page, and some block it silently. Look for a prompt or a blocked-download icon in the address bar, allow it, and run the split again.
Does the extracted PDF keep bookmarks and form fields?
Page content, text and images are preserved exactly. Document-level features such as bookmarks, the table of contents and interactive form fields are tied to the original document structure and are generally not carried into the new file.
Is there a page or size limit?
No limit is imposed by the tool. The practical ceiling is your device memory, because the document is held in RAM while it is processed. Large documents are slower on phones than on laptops.
Does it work offline?
Yes. Once the page has loaded, everything it needs is already on your device. You can switch to airplane mode and the tool keeps working normally.
Is this the same as separating or cutting a PDF?
Yes. Separate PDF, cut PDF and split PDF name one thing: choosing a range of pages and getting them back as their own document. You can split PDF files into single pages, or pull out one chapter and leave the rest alone.
Can I split PDFs in bulk?
One document at a time. Separate PDFs individually rather than in a batch, because the page ranges you want almost never line up across different files — and a batch split at a fixed range quietly produces the wrong result for most of them.
