How to Split a PDF — Extract Pages, Split by Range, Free in 2022
Step-by-step guide to splitting a PDF online — extract specific pages, split by page range, or break a doc into pieces. Free, no sign-up, no watermark. Tested on desktop and mobile.
Splitting a PDF sounds trivial — until the free tools you find lock you out after the second file or stamp a watermark on the output. This guide walks through the cleanest way to split a PDF in 2022, whether you need a single page extracted or a whole document chopped into chapters. No watermark, no sign-up, no software to install.
Why split a PDF?
People split PDFs for the same handful of reasons every day:
- Sharing a single page — pulling page 4 of a contract for a colleague who doesn't need the other twenty.
- Email size limits — splitting a 60 MB document into three 20 MB pieces so each fits the attachment cap.
- Extracting a chapter from a book or report for personal reading.
- Separating receipts when a single scan contained ten of them.
- Removing pages — a related but distinct task that we cover with the remove pages tool.
The underlying operation is the same: take one PDF, produce one or more smaller PDFs whose pages come from the original.
Three ways to split a PDF
Online splitters generally support three split modes. Knowing which one to pick saves you from doing the job in two steps.
1. Extract specific pages
You list the page numbers you want and the splitter produces one PDF containing only those pages. Good for pulling a couple of pages out of a long document.
2. Split by page range
You list one or more ranges — each range becomes its own output PDF. For example, splitting a 30-page document with 1-10,11-20,21-30 gives you three 10-page files.
3. Split every N pages
You specify N and the splitter chops the document into fixed chunks. A 50-page PDF split every 5 pages becomes 10 files.
When to use which
Extract for a single page or a small selection. Split by range for chapter-style boundaries. Split every N when you need equal-size chunks — say, for an email attachment limit.
Step-by-step: split in convertpdfgo
Total time: under a minute for typical-sized files.
Open the split tool
Go to convertpdfgo.com/split. The page loads in under a second and shows a drop zone in the middle.
Drop your PDF
Drag the file into the drop zone or click to pick it. Files up to 30 MB work as a guest; sign in to lift the cap to 50 MB.
Choose your split mode
Pick Extract pages, Split by ranges, or Split every N from the tab strip at the top.
The visual page picker shows every page as a thumbnail — click to select, or type the page numbers directly into the text field if you already know them.
Hit Split now
We use pdfcpu in relaxed validation mode, so even older or slightly malformed PDFs split without complaints.
For typical files, the split finishes in under 3 seconds.
Download the pieces
Each output PDF appears as its own download button. Single outputs download directly; multiple outputs are also bundled into a zip you can grab in one shot.
The files are watermark-free, bit-for-bit clean.
Page range syntax cheat sheet
The text field accepts a small grammar that covers most needs. A quick reference:
| Input | Means | Output |
|---|---|---|
| 5 | Page 5 only | 1 PDF (1 page) |
| 1-5 | Pages 1 through 5 | 1 PDF (5 pages) |
| 1,3,7 | Pages 1, 3, and 7 | 1 PDF (3 pages) |
| 1-3, 7-10 | Two ranges (split-by-ranges mode) | 2 PDFs |
| 3- | Page 3 to the end | 1 PDF |
| -5 | Beginning to page 5 | 1 PDF |
The same grammar works in our extract pages tool and in the remove pages tool.
Split a PDF on your phone
The same flow works on iOS and Android. The visual page picker adapts to touch — tap pages to select instead of click, and long-press one to drag-select a range.
- Tap the drop zone and pick the PDF from your Files (iOS) or Files / Downloads (Android).
- Pick a split mode from the tabs.
- Tap thumbnails to select pages, or type the range manually.
- Tap Split now. The downloads land in your phone's default folder.
Common problems and how to fix them
My output split has all the original pages instead of just the ones I picked
That happens in split-by-ranges mode when you only enter one range — the splitter assumes you want the whole document chopped at that range. Switch to Extract pages mode if you want exactly the pages you listed and nothing else.
Splitting a password-protected PDF fails
Unlock the PDF first with our unlock PDF tool, then drop the unlocked version into the splitter.
The splitter rejects my file as 'not a valid PDF'
The file probably isn't a real PDF — a common cause is a 404 page accidentally saved as "result.pdf". Open the file in any PDF reader to confirm. If it doesn't open there, the file is corrupted.
My ranges produced too many files
You probably used split-by-ranges when you wanted extract. Switch modes — each range becomes a separate file in split-by-ranges, but extract puts everything into one output.
Privacy: where does your file go?
Splitting happens server-side because PDFs need binary parsing tools that don't run reliably in the browser. The trade-off: your file leaves your device temporarily.
convertpdfgo's policy in plain English:
- Files travel encrypted (TLS 1.3) — same standard as banks and email providers.
- Files are stored encrypted at rest on our servers in Germany.
- Files are automatically deleted within one hour of processing.
- We never look at your content, share it, or train AI on it.

Next steps
You came to split a file and probably want to do one of these next:
- Compress each split if file size is the reason you split in the first place.
- Merge selected splits with other documents.
- Sign individual splits before sending them to different people.
- Password-protect a split containing sensitive pages.
- Extract pages if your real need was pulling a subset, not chopping the doc.
