Splitting a PDF file is the opposite of merging — instead of combining documents, you're separating one large PDF into smaller, more manageable pieces. Whether you need to extract a single page, separate a document into chapters, or remove unwanted pages from a file, a PDF splitter is an essential tool to have in your toolkit.
This complete guide covers everything you need to know about splitting PDFs online — when to do it, how to do it step by step, and expert tips for getting exactly the output you need.
What Does Splitting a PDF Mean?
Splitting a PDF means dividing a single PDF document into two or more separate PDF files. You can split by page ranges (e.g., pages 1–5 go to one file, pages 6–10 go to another), extract specific individual pages, or split every page into its own separate file.
The splitting process does not alter the content of any page. All text, images, annotations, and formatting are preserved exactly as they were in the original document.
When Would You Need to Split a PDF?
- Extracting specific pages: Pull out one or two pages from a 50-page report to share with a colleague.
- Separating chapters or sections: Divide a long document into individual chapters for easier distribution.
- Removing unwanted pages: Split out the pages you want and discard the rest — effectively deleting pages from a PDF.
- Reducing file size for email: Send only the relevant section of a large document instead of the whole file.
- Creating page-specific handouts: Extract individual slides or pages to share as standalone documents.
- Separating merged invoices: When you have a PDF with multiple invoices, split each one into its own file.
- Archiving by section: Organize a large reference document by splitting it into logically named sections.

Different Ways to Split a PDF
Method 1: Split by Page Range
This is the most common split method. You specify which pages go into which output file. For example, if you have a 20-page report, you could split it into pages 1–7 (introduction), 8–15 (main content), and 16–20 (appendix). Each range becomes a separate PDF file.
Method 2: Extract Specific Pages
If you only need certain pages — say page 3, page 7, and page 12 from a 30-page document — you can enter those page numbers specifically. The tool extracts only those pages and creates a new PDF containing just the pages you requested.
Method 3: Split Every Page
This option creates one separate PDF file for every single page in the original document. If you have a 10-page PDF, you get 10 individual one-page PDFs. This is useful when you need to archive, sort, or individually label every page of a document.
How to Remove Pages from a PDF by Splitting
The split tool also works as an effective page removal tool. If you want to remove pages 4 and 5 from a 10-page PDF, you'd split the document into two ranges: pages 1–3 and pages 6–10. Then merge these two output files together using the Merge PDF tool to get a clean 8-page PDF with pages 4 and 5 removed.
PDF Splitting for Different Use Cases
| Use Case | Best Split Method | Result |
|---|---|---|
| Share one page from a report | Extract specific page | Single-page PDF |
| Divide document into chapters | Split by page ranges | Multiple chapter PDFs |
| Remove unwanted pages | Split + Re-merge desired ranges | Cleaned PDF |
| Separate combined invoices | Split every page | Individual invoice PDFs |
| Create handouts | Extract specific pages | Handout PDF |
Tips for Splitting PDFs Effectively
- Know your page numbers first: Open the PDF in a viewer before splitting to note exactly which page numbers you need. Remember that page 1 in the PDF might be labeled differently in the document header.
- Name output files clearly: After splitting, rename your output files with descriptive names before working with them further.
- Compress if needed: If an extracted section is still large, run it through the Compress PDF tool to reduce the file size.
- Combine split with merge: The split and merge tools work perfectly together for complex PDF reorganization tasks.
Splitting PDFs on Mobile
The ShoXTools Split PDF tool works fully on mobile browsers. On an iPhone or Android device, open your browser, go to ShoXTools, and use the tool exactly as you would on a desktop. File selection on mobile will open your device's file picker where you can select PDFs from your device storage or cloud drive.
Why Use an Online PDF Splitter Instead of Software?
Desktop PDF software like Adobe Acrobat Pro costs a monthly subscription fee and requires installation. Online tools like ShoXTools give you the same core splitting functionality — instantly, for free, with no installation — and process everything locally in your browser for maximum privacy. For occasional PDF splitting tasks, an online tool is almost always the better choice.
