What is Split PDF?
Split PDF is a free browser-based tool that divides a PDF document into multiple smaller files according to your specifications. This tool offers three flexible splitting methods: split every page into its own file, split by custom page ranges, or split every N pages automatically. All processing happens entirely in your browser using JavaScript, which means your PDF files are never uploaded to any server. Your documents remain completely private and secure throughout the entire process. The splitting engine reads your PDF structure and creates new independent PDF documents containing only the specified pages. Each output file is a fully valid PDF that can be opened in any PDF reader. Text, images, annotations, and formatting are preserved perfectly in every split file. This tool is ideal for breaking apart large documents into manageable sections, extracting specific chapters from ebooks, separating individual forms from a batch scan, or dividing a presentation into topic-based segments. The range-based splitting supports flexible input formats like 1-3, 5, 7-10 so you can precisely control which pages go into each output file. There is no file size limit beyond your browser's memory capacity, no registration required, and no watermarks added to the output. The split files are available for individual download immediately after processing.
How to Use
- Upload the PDF file you want to split.
- Choose the split method (by page, by range, every N pages).
- Click the 'Split' button.
- Download the split PDFs.
Tips & Best Practices
- Use the range-based split mode for maximum control. You can specify non-contiguous ranges like 1-3, 7-9, 15-20 to create exactly the documents you need.
- The every-N-pages mode is perfect for splitting large scanned documents into uniform sections, such as separating a book into chapters of equal length.
- Preview your PDF page count before splitting to ensure your range inputs are within the valid page numbers.
- For duplex-scanned documents, try splitting every 2 pages to separate individual sheets into their own files.
- After splitting, you can use the Merge PDF tool to recombine specific split files if you need a different arrangement.

FAQ
How do I split a PDF?
Upload your PDF, then choose a split method: by individual pages, by custom ranges, or every N pages.
Can I download each split file individually?
Yes, each split PDF has its own download button.
How does PDF splitting technically work?
PDF splitting extracts specified pages from the original document and creates independent new PDF files. The quality and formatting of the original pages are fully preserved.
Are my files uploaded to a server?
No, all processing happens entirely in your browser and no files are sent to any external server. It is completely safe.
Can I split a password-protected PDF?
Password-protected PDFs must first be unlocked using the 'Remove Password' tool before splitting.
When is 'split every N pages' useful?
For example, it is convenient for dividing a 100-page document into 10-page sections, or separating a duplex-scanned document into 2-page units.
Can I split a PDF into specific page ranges?
Yes, use the range-based split mode and enter your desired ranges separated by commas, for example 1-5, 6-10, 11-15. Each range creates a separate PDF file.
What happens to the original PDF after splitting?
The original PDF remains completely unchanged. Splitting creates new PDF files from copies of the specified pages without modifying the source document.
Can I split a very large PDF file?
Yes, you can split files up to 100MB. Processing speed depends on your device's capabilities since everything runs in your browser.
Are form fields and annotations preserved in split files?
Yes, all page content including form fields, annotations, and embedded media are preserved in each split output file.
Can I split a scanned PDF?
Yes, scanned PDFs are split the same way as text-based PDFs. Each page's scanned image is preserved exactly as it appears in the original.
How do I download all split files at once?
Each split file has its own download button. You can download them one by one after the splitting process completes.
