3. Detailed Step-by-Step Guide

1

Upload Your PDF

Start by uploading the PDF you want to split. The tool will analyze the file and display a page preview. You can see thumbnails of all pages to help you decide how to split the document.

💡 Pro Tips:

  • • Check the total page count before splitting
  • • Verify the PDF is not corrupted or password-protected
  • • Ensure file size is under 150MB
2

Choose Split Method

You have multiple options: Split by page ranges (e.g., pages 1-10, 11-20), extract specific pages (e.g., pages 5, 8, 12), or split every N pages (e.g., every 5 pages). Select the method that best fits your needs.

💡 Pro Tips:

  • • Use page ranges for sequential splits
  • • Extract specific pages for non-sequential content
  • • Split every N pages for uniform document sizes

Define Page Ranges

Enter your page ranges in the format "1-10" or individual pages like "5,8,12". You can create multiple ranges. The tool will generate separate PDFs for each range or extracted page.

💡 Pro Tips:

  • • Use commas to separate multiple ranges: "1-5,10-15,20"
  • • Preview pages before confirming ranges
  • • Remember page numbers start from 1, not 0

Process and Download

Click "Process" to split your PDF. The tool creates separate files for each range. You'll receive a ZIP file containing all split PDFs, or individual downloads depending on the number of splits.

💡 Pro Tips:

7. Troubleshooting Common Issues

⚠️ File Won't Upload or Process

If your file won't upload, check the following:

  • File format is supported: .pdf
  • File size is under 150MB limit
  • File is not corrupted or password-protected
  • Browser is up-to-date and JavaScript is enabled
  • Try a different browser if issues persist

⏱️ Processing Takes Too Long

Large files or complex documents may take longer. Close other browser tabs, ensure stable internet connection, and be patient. If processing exceeds 5 minutes, try splitting the file or reducing its complexity.

📊 Output Quality Issues

Verify source file quality first. Use original, high-resolution files. Check tool settings for quality options. For scanned documents, ensure original scan quality is good. Some quality loss is normal with compression tools.

💾 Download Issues

If download fails, check browser download settings, ensure sufficient disk space, and try right-clicking the download link to "Save As". Clear browser cache if downloads consistently fail.
