Indigo PDF offers a feature to remove blank pages from PDF documents, which can be especially useful when dealing with scanned documents or PDFs with unnecessary empty pages. Here are the steps to remove blank pages from a PDF using Indigo PDF:

1. Select PDF from Local Storage:
   • Use the application’s file selection or upload feature to choose the PDF document from which you want to remove blank pages. The selected PDF will be uploaded to the application.
2. Configure Removal Settings:
   • Indigo PDF allows you to adjust removal settings to specify what constitutes a “blank” page:
     • Pixel Whiteness Threshold: Set the threshold for determining how white a white pixel must be to be classified as ‘White.’ A value of 0 is pure black, while 255 is pure white. Adjust this threshold to suit your specific document.
     • White Percent (%): Define the percentage of the page that must consist of ‘white’ pixels for it to be considered a blank page and subsequently removed.
3. Start Blank Page Removal:
   • After configuring the removal settings, click the “Remove Blank Pages” or “Start Removal” button to initiate the blank page removal process.
4. Download the Cleaned PDF:
   • Once the removal process is complete, you will be prompted to download the cleaned PDF document. Choose a destination folder on your computer to save the PDF without the blank pages.
5. Confirmation:
   • You will receive confirmation that the blank pages have been successfully removed from the PDF, and the cleaned document is ready for use or distribution.

By following these steps, you can efficiently eliminate blank pages from a PDF using Indigo PDF, streamlining your documents and making them more concise and user-friendly.
