Split PDF File

Divide and Conquer Your PDFs

Need just a few pages from a massive document? Our PDF Splitter lets you extract exactly what you need.

Select specific pages or ranges, and create a new, smaller PDF in seconds. Perfect for sharing just the relevant parts without the clutter.

Why Split PDF Files?

Share Specific Sections

Extract only relevant pages from lengthy reports, manuals, or contracts to share with colleagues or clients. Instead of sending a 100-page manual, split and send just the 5 pages needed, saving bandwidth and recipient time.

Email Size Restrictions

Most email services limit attachments to 25MB. Splitting large PDFs into smaller chunks ensures successful delivery. This is especially critical when sharing scanned documents, presentations, or image-heavy materials.

Organize Documents Efficiently

Separate multi-document PDFs into individual files for better organization. Split course materials by chapter, break invoices into monthly files, or extract individual forms from government document packages.

Compliance & Confidentiality

Extract non-sensitive pages while protecting confidential information. Legal professionals can share relevant contract sections without disclosing private client details or financial data.

How to Split PDF Files

Method 1: Extract Specific Pages

1. Upload your PDF file (drag & drop or click to browse)
2. Select "Extract Pages" mode
3. Enter page numbers or ranges (e.g., "1-5, 8, 12-15")
4. Click "Split PDF" to create a new document with selected pages
5. Download the extracted PDF

Method 2: Split All Pages (Coming Soon)

The "Split All Pages" feature will create individual PDF files for each page, compressed into a downloadable ZIP archive. This is perfect for creating flashcards, separating scanned documents, or archiving individual forms.

Page Range Syntax Guide

• Single pages: "1, 5, 9" (extracts pages 1, 5, and 9)
• Page ranges: "1-10" (extracts pages 1 through 10)
• Combined: "1-3, 7, 12-15" (extracts pages 1, 2, 3, 7, 12, 13, 14, 15)
• Reverse order: Automatically sorted in ascending order
• Duplicates: Each page extracted only once even if listed multiple times

Best Practices

Before Splitting

• Open the PDF in a viewer to confirm page numbers (numbering starts at 1)
• Verify the total page count shown after upload
• Note that PDF page numbers may differ from document page numbers (e.g., book page "23" might be PDF page 35)
• Check for blank pages that might affect numbering

Page Selection Strategy

• Extract table of contents/index pages for reference
• Include title pages for context
• Capture page ranges rather than scattered individual pages when possible
• Double-check page numbers before final split

After Splitting

• Rename extracted files descriptively (e.g., "contract-exhibit-a.pdf")
• Verify page count matches your selection
• Keep original files as backups
• Organize split files in appropriate folders

Privacy & Security

All PDF splitting happens entirely in your browser using the pdf-lib JavaScript library. Your files never upload to our servers or any external service. This ensures complete privacy for confidential contracts, medical records, financial documents, and personal files. Once you close the browser, no trace of your document remains on our site.

Technical Details

Supported Features

• Preserves original PDF formatting, fonts, and images

Troubleshooting

Invalid Page Range Error

Problem: Error message when entering page numbers.

Solutions:

• Ensure page numbers are within the document range (check page count)
• Use correct syntax: "1-5" not "1 to 5"
• Separate ranges/pages with commas: "1-3, 7" not "1-3 7"
• Avoid special characters except hyphens and commas

No Pages Extracted

Problem: Downloaded PDF is empty or has 0 pages.

Solutions:

• Double-check your page range syntax
• Verify page numbers don't exceed total page count
• Try extracting a simple range like "1-2" to test
• Refresh the page and try again

File Won't Upload

Problem: PDF file doesn't load after selection.

Solutions:

• Ensure file is a valid PDF (not Word .docx or image)
• Try a smaller PDF first to test functionality
• Check browser console for JavaScript errors
• Try a different browser (Chrome, Firefox recommended)
• Disable browser extensions that might block JavaScript

Browser Crashes or Freezes

Problem: Browser becomes unresponsive during split operation.

Solutions:

• Reduce file size by compressing PDF before splitting
• Close other browser tabs to free memory
• Try splitting smaller page ranges instead of the entire document
• Use a desktop browser instead of mobile for large files

Alternatives to Splitting

When to Use Other Tools

• Remove pages: Use PDF delete pages tool if you want the opposite (keep most, remove few)
• Reorder pages: Use PDF page reorder tool to rearrange before splitting
• Merge after split: Use PDF merge tool to recombine extracted sections differently
• Print to PDF: In desktop apps, print selection to new PDF (less precise)
