Take a moment to verify this information matches your expectations.

Choosing Split Method

Option A: Split All Pages Individually

This automatically selects all pages for extraction
Each page will become a separate PDF file
Ideal when you need to extract every page separately

Option B: Split Custom Page Ranges

Select the “Split by custom page ranges” option
Use one of these methods to specify pages:

Method 1: Text Input

Enter page ranges in the text field using this syntax:
Single pages: 5 (extracts only page 5)
Page ranges: 1-3 (extracts pages 1, 2, and 3)
Combinations: 1-3, 5, 7-9 (extracts pages 1-3, 5, and 7-9)
Click “Validate Range” to verify and visually see selected pages

Method 2: Visual Selection

The selection counter updates in real-time
Selected pages highlight with a blue border

Troubleshooting

Common Issues and Solutions

File Upload Problems

Issue: “Please select a valid PDF file” error
Solution: Ensure your file is actually a PDF and not a differently named file. Check file extension and try re-saving as PDF if necessary.
Issue: “File size exceeds 50MB limit” error
Solution: Use a PDF compressor tool first, or split the document into smaller sections manually.

Page Range Errors

Issue: “Invalid range” or “out of bounds” errors
Solution: Verify page numbers exist in your document. Remember page numbering starts at 1, not 0.
Issue: Range validation fails unexpectedly
Solution: Ensure proper syntax: use commas between ranges, hyphens for ranges, no spaces around hyphens.

Processing Problems

Issue: Processing seems stuck or extremely slow
Solution: Large documents with complex graphics may take longer. Be patient, or try splitting smaller ranges first.
Issue: “Failed to split PDF” error
Solution: The PDF may be encrypted or corrupted. Try opening it in a PDF viewer first to verify integrity.

Download Issues

Issue: Download buttons not working
Solution: Check if your browser is blocking pop-ups. Ensure sufficient storage space on your device.
Issue: ZIP file won’t open or appears corrupted
Solution: Try downloading individual files instead. The issue may be with your ZIP extraction software.

Performance Optimization Tips

For Large Documents

Split documents in smaller batches if experiencing performance issues
Close other browser tabs and applications to free up system resources
Consider using a computer rather than mobile device for very large PDFs

For Faster Processing

Use the custom range option instead of splitting all pages when you only need specific pages
Avoid unnecessary page selections in the visual interface
Use text range input for precise control when dealing with many pages
