Indigo PDF provides a convenient feature for compressing PDF files, helping you reduce their size while maintaining reasonable quality. You can choose between manual or automatic compression. Here are the steps to compress a PDF using Indigo PDF:

1. Open PDF for Compression:
   • Use the application’s file selection or upload feature to choose the PDF document that you want to compress.
2. Choose Compression Mode:
   • Select your preferred compression mode:
     • Manual Mode: In manual mode, you have control over the compression level. You can set the optimization level from 1 to 4, with 4 being the highest compression, but it may slightly reduce image quality.
     • Auto Mode: Auto mode adjusts the compression quality automatically to achieve the exact PDF size you specify.
3. Set Optimization Level (Manual Mode):
   • If you opt for manual mode, select the optimization level that suits your needs. Higher levels provide more compression but may reduce image quality. Choose the appropriate level based on your preferences.
4. Enter Expected PDF Size (Auto Mode):
   • If you choose auto mode, enter the expected size you want for the compressed PDF. You can specify the size in various units, such as megabytes (MB) or kilobytes (KB). For example, you can enter “25MB,” “10.8MB,” or “25KB.”
5. Start Compression:
   • After configuring the compression mode and settings, click the “Start Compression” or “Compress” button to initiate the compression process.
6. Download the Compressed PDF:
   • Once the compression process is complete, you will be prompted to download the compressed PDF file. Choose a destination folder on your computer and provide a name for the compressed PDF if needed.
7. Confirmation:
   • You will receive confirmation that the PDF has been successfully compressed, reducing its size while maintaining an acceptable level of quality.

By following these steps, you can efficiently reduce the size of your PDF documents using Indigo PDF. This is particularly useful for optimizing PDFs for email attachments, web uploads, or other situations where a smaller file size is preferred
