How to split pages from a PDF
Upload the PDF you want to split
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.
Enter the page range to extract
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.
Choose an output file name
Enter a name for the split PDF. Invalid characters are cleaned automatically and .pdf is added if you omit it.
Split the PDF
Click the Split PDF button. A progress line updates as each selected page is copied into the new document.
Download the new PDF
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.
Frequently asked questions
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'.
