PDF Split Features
Split your PDF exactly how you need.

Output
Browser-side splitting can keep files on your device when that workflow is supported.
Processing time depends on file size, page count, browser support, and device memory.
Download each split part individually.
Key Takeaways
- PDF splitting uses pdf-lib in the browser when the file, browser, and device support it.
- Three modes are available: Page Range pulls listed pages like 1-3, 5, 7-9 into one PDF, Every N Pages breaks the file into equal chunks, and Extract All Pages turns every page into its own PDF.
- Page Range always produces a single combined PDF, so use Every N Pages or Extract All Pages when you need multiple separate output files.
- Password-protected PDFs cannot be split here, and practical limits depend on page count, PDF size, browser support, and device memory.
PDF Splitting Tips
Extract specific pages
Use the page range selector to extract only the pages you need. For example, extracting pages 3-7 from a 50-page report gives you just the relevant section.
Splitting forms and invoices
If you have a batch of scanned forms or invoices merged into one file, splitting by page count creates individual files for each document.
Reduce email attachment size
Split a large presentation or report into smaller chapters so each part fits within email attachment limits. Recipients get a cleaner reading experience.
Private by design
PDF splitting runs entirely in your browser, so your files are never uploaded to any server and never leave your device.
How to Split a PDF in Your Browser
Load your PDF
Drag a PDF onto the upload area or click to browse and select one. pdf-lib reads the file in the browser when supported, and the tool reports how many pages it contains. For sensitive documents, confirm the active workflow before processing.
Pick a split mode
Choose Page Range to pull specific pages such as 1-3, 5, 7-9 into one file, Every N Pages to break the document into equal chunks of N pages, or Extract All Pages to turn every page into its own PDF.
Split and download each part
Click Split PDF. Each resulting file appears in the results list with its page count, size, and a dedicated Download button, so you can save only the parts you need.
Choosing the Right Split Mode
This splitter offers three modes. The mode you pick controls how many output files you get and how pages are grouped. All modes copy pages exactly as they are, preserving fonts, images, and layout.
| Mode | What you enter | Output files | Best for |
|---|---|---|---|
| Page Range | Ranges like 1-3, 5, 7-9 | One PDF with the selected pages | Pulling a chapter or a few specific pages |
| Page Range (single) | A single number such as 5 | One PDF with that one page | Extracting one page on its own |
| Every N Pages | A chunk size, e.g. 3 | Several PDFs of N pages each | Booklets, handouts, batched scans |
| Extract All Pages | Nothing extra | One PDF per page | Separating every page individually |
| All modes | A source PDF | Named with the page range for clarity | Keeping output files easy to identify |
Which Approach Fits Your File
I need one section
Use Page Range and type the span, like 12-18. The tool collects those pages into a single new PDF you can download in one click.
I have merged scans
If several forms or invoices were scanned into one file, Every N Pages with a matching chunk size separates them into individual documents automatically.
I want every page apart
Choose Extract All Pages. Each page becomes its own PDF, each listed with a separate Download button for selective saving.
My file is large
There is no fixed page limit, but splitting runs in your browser, so very large PDFs depend on your device memory and may take a little longer.
Common Problems and Fixes
It says no valid pages were found
Your range likely falls outside the document. Page numbers start at 1 and cannot exceed the total page count shown after loading. Adjust the numbers and try again.
My password-protected PDF will not open
Encrypted PDFs cannot be split here. Remove the password in a PDF editor first, then upload the unlocked file.
The range mode gave me one file, not several
Page Range always produces a single PDF containing every page you listed. To get multiple files, switch to Every N Pages or Extract All Pages.
Nothing happens when I click Split
Make sure a PDF is loaded and that JavaScript is enabled. Reload the page and re-select the file if needed.
How to Split a PDF
Upload your PDF, choose a split mode, and download the resulting parts.
Frequently Asked Questions
How is my PDF processed?
Splitting can run in your browser using pdf-lib when supported.
For sensitive documents, confirm the browser-side workflow before processing.
The “every N pages” mode divides the PDF into equal chunks.
How do I enter page ranges?
Use commas to separate ranges, e.g. 1-3, 5, 7-9.
This would extract pages 1, 2, 3, 5, 7, 8, and 9 into a single output PDF.
Use caution with sensitive documents and verify the processing workflow first.
What does Every N Pages mean?
Setting N=3 on a 9-page PDF creates three 3-page PDFs.
Useful for splitting handouts or booklets.
Decrypt the PDF first if you have the password.
Can I extract a single page?
Yes. Use page range mode and enter just the page number, e.g. 5.
This extracts only page 5 as a new PDF.
Page numbers start from 1.
Is there a page limit?
Practical limits depend on page count, file size, browser support, and device memory.
Very large PDFs may take longer or require a different workflow.
File names include the page range for easy identification.
Will the output files keep all formatting?
Yes. All fonts, images, and formatting are preserved.
The split simply copies the specified pages to a new PDF.
The split process copies selected pages into new PDF files.
Is this tool free?
Yes, completely free with no account required.

Can I split a password-protected PDF?
No. Remove the password first using a PDF editor.
