    • Clean, responsive design
  4. Technical Approach:

  5. Privacy Focused:
    • Files never leave your computer

How to Use:

  1. Drag and drop a PDF file or click "Select PDF File"
  2. Adjust compression settings (quality and resolution)
  3. Click "Compress PDF"
  4. When complete, click "Download Compressed PDF"

Note: For very large PDFs (100+ pages), the compression process may take some time as it's all done in the browser. The compression works best on PDFs that contain scanned images or photographs. Text-heavy PDFs may not compress as effectively with this method.
