Split a PDF into multiple documents.
Drag and drop your PDF into the upload area or click to browse for the file. The tool checks the file and shows the total number of pages.
In the page range field, type which pages you want in the new PDF. Use commas and ranges, for example 1-3,5,8. Leave the field empty to keep all pages.
Enter a name for the split PDF. Invalid characters are cleaned automatically and .pdf is added if you omit it.
Click the Split PDF button. A progress line updates as each selected page is copied into the new document.
When splitting is complete, your browser downloads the new PDF containing only the selected pages. If the download is blocked, adjust your browser’s download or popup settings and try again.
Split a PDF into multiple documents.
Nextooly’s PDF Split tool lets you quickly extract specific pages or split a large PDF into smaller, more manageable documents—without ever uploading your file to a server. All splitting and page copying are done locally in your browser using pdf-lib, so your data stays private and secure.
You can define flexible page ranges like 1-3, 5, 7-10 or combinations such as 1-2,4,8-9, and the tool validates them before processing to avoid mistakes. This makes it ideal for separating chapters, isolating invoices, extracting only relevant sections from reports, or breaking down large scanned PDFs into lighter files.
Example
Input: The source text, file, or settings you want to work with.
Output: A clean pdf split result ready for the next step.

Does this PDF splitter upload my file to any server?
No. All splitting happens entirely in your browser using pdf-lib. Your PDF never leaves your device, and nothing is uploaded or stored.
Why does the tool say my PDF is password-protected?
If pdf-lib detects that the PDF is encrypted, it cannot be opened in-browser. Remove the password using your PDF reader (e.g., 'Save as' without encryption) and try again.
How do I select the pages to extract?
Use a range like `1-3`, or a comma list like `2,5,7`, or a combination such as `1-2,4,6-8`. Leaving the field empty extracts all pages.
What happens if I enter an invalid range?
If a page number is out of bounds or the range format is invalid, the tool shows an error (e.g., 'Invalid range: 3-1' or 'Invalid page: 12'). The PDF is not processed until the issue is fixed.
Why is only one PDF supported at a time?
This tool is designed for single-document splitting. After downloading your split PDF, you can upload another and repeat the process.
Can this tool delete pages from the original PDF?
No. Your original file is never modified. The tool creates a new PDF containing only the pages you selected.
Why does splitting sometimes take time?
Large PDFs or documents with many pages require more processing when copying pages into the new PDF. Browser performance and device memory also affect processing time.
Why did I get 'No valid pages selected to split'?
This happens when the page range resolves to zero pages—usually due to invalid numbers, typos, or ranges that exceed the document’s page count.
Can I rename the output file?
Yes. Enter any custom name in the Output file name box. If left empty, the default name will be 'split.pdf'.
