🔧 How It Works

1. Auto Compression: Uses binary search to find the optimal DPI that achieves the target file size
2. Manual Compression: Converts PDF pages to images at specified DPI and recreates the PDF
3. PDF to PPT: Extracts each page as an image and creates PowerPoint slides

💡 Tips

• Higher DPI = better quality but larger file size
• Auto compression may take longer but provides precise size control
• For best results, start with the auto compression feature
• Use the GUI for interactive file selection and real-time progress
• Use CLI for batch processing and automation
