Common Use Cases:

• Combining multiple reports into one document
• Merging scanned documents
• Creating comprehensive portfolios
• Consolidating invoices or receipts
• Building complete documentation sets

Splitting PDFs

What is PDF Splitting? Dividing a single PDF file into multiple smaller files, either by page ranges or at specific break points.

Common Use Cases:

• Extracting specific pages from large documents
• Separating chapters from books
• Splitting invoices for individual clients
• Creating individual files from scanned batches
• Organizing large documents into manageable pieces

• Verify all files are PDFs before merging

Quality Considerations:

• Merged PDF maintains original quality
• All formatting and images preserved
• Bookmarks and metadata may be combined
• Page numbers continue sequentially

Common Merging Scenarios:

Scenario 1: Combining Reports

Scan_003.pdf
→ Complete_Document.pdf

Scenario 3: Creating Portfolios

Resume.pdf
Cover_Letter.pdf

How to Split PDF Files

Step-by-Step Splitting Guide

1. Access the PDF Tools

   • Navigate to our PDF Tools page
   • Select the "Split" tab

2. Upload Your PDF File

   • Click "Add PDF File" or drag and drop
   • Maximum file size: 25MB

3. Choose Split Method

   Method 1: Split by Page Ranges

   • Enter specific page ranges (e.g., "1-5, 10-15, 20-25")
   • Each range creates a separate PDF
   • Use commas to separate ranges
   • Use hyphens for page ranges

   Method 2: Split Every N Pages

   • Enter number of pages per file
   • Automatically splits into equal parts
   • Useful for large documents

   Method 3: Split at Specific Pages

   • Enter page numbers where to split
   • Creates files between split points
   • Useful for chapter divisions

4. Process and Download

   • Click "Split PDF" button
   • Wait for processing
   • Download all split files as a ZIP archive
   • Original file remains unchanged

Splitting Best Practices

Page Range Format:

• Single pages: 5 (creates file with page 5 only)
• Page ranges: 1-10 (pages 1 through 10)
• Multiple ranges: 1-5, 10-15, 20-25
• Mix formats: 1-3, 5, 7-10

Common Splitting Scenarios:

Scenario 1: Extract Specific Pages

Original: 50-page document
Split: Pages 1-5, 10-15, 20-25
Result: 3 separate PDFs

Scenario 2: Split by Chapters

Original: 200-page book
Split: Every 20 pages
Result: 10 chapter files

Scenario 3: Separate Invoices

Original: 12 invoices (1 per page)
Split: Every 1 page
Result: 12 individual invoice files

Advanced PDF Management Techniques

Combining Merge and Split Operations

Workflow Example:

1. Split large PDF into chapters
2. Edit individual chapters
3. Merge edited chapters back together
4. Create final document

Organizing Large Document Sets

Strategy:

• Split large documents into logical sections

What May Be Affected:

• ⚠️ Bookmarks (may need regeneration)
• ⚠️ Cross-document links
• ⚠️ Embedded media (depends on PDF structure)

Common PDF Management Challenges

Challenge 1: File Size Limits

Problem: PDFs exceed 25MB limit Solution:

• Split large PDFs first
• Process in smaller batches

• Preview page ranges before splitting

Challenge 4: Processing Speed

Problem: Large PDFs take too long to process Solution:

• Split large files into smaller chunks
• Process during off-peak times
• Ensure stable internet connection
