📖 Usage

CLI Commands

After installation, you can use pdf-zipper or pdfzip commands:

# Launch GUI
pdf-zipper gui

# Compress PDF to specific size (auto mode)
pdf-zipper compress input.pdf --target-size 5.0

# Compress PDF with specific DPI (manual mode)
pdf-zipper compress input.pdf --dpi 150

# Convert PPTX to PDF (new feature!)
pdf-zipper compress presentation.pptx

# Convert PDF to PowerPoint
pdf-zipper convert input.pdf

# Convert PowerPoint to PDF (new feature!)
pdf-zipper convert presentation.pptx

# Show file information (supports PDF and PPTX)
pdf-zipper info input.pdf
pdf-zipper info presentation.pptx

# Show help
pdf-zipper --help

The CLI provides rich, colorful output with progress indicators and detailed information (see CLI screenshot above).

GUI Mode

pdf-zipper gui

The GUI provides an intuitive interface with file browser, drag & drop support, and real-time progress logging (see screenshot above).

Programmatic Usage

from pdf_zipper import autocompress, autocompress_pdf, autocompress_pptx, autocompress_pdf_to_pptx, compress_pdf, convert_to_ppt

# Universal auto compression (supports format conversion)
autocompress("input.pdf", "output.pdf", 5.0, print)      # PDF → PDF
autocompress("input.pptx", "output.pptx", 5.0, print)    # PPTX → PPTX
autocompress("input.pdf", "output.pptx", 5.0, print)     # PDF → PPTX (NEW!)

# Specific auto compression functions
autocompress_pdf("input.pdf", "output.pdf", 5.0, print)           # PDF → PDF
autocompress_pptx("input.pptx", "output.pptx", 5.0, print)        # PPTX → PPTX
autocompress_pdf_to_pptx("input.pdf", "output.pptx", 5.0, print)  # PDF → PPTX (NEW!)

# Manual compression and conversion
compress_pdf("input.pdf", "output.pdf", 150, print)      # Manual PDF compression
convert_to_ppt("input.pdf", "output.pptx", 150, print)   # PDF → PPTX conversion

• Pillow
• python-pptx
• rich
• textual
• typer

🔧 How It Works

1. Auto Compression:
   • PDF → PDF: Uses binary search to find the optimal DPI that achieves the target file size
   • PPTX → PPTX: Converts PPTX → PDF → optimizes DPI → converts back to PPTX
   • PDF → PPTX: Optimizes PDF DPI → converts to PowerPoint format (NEW!)
2. Manual Compression: Converts PDF pages to images at specified DPI and recreates the PDF
3. Format Conversion:
   • PDF to PPT: Extracts each page as an image and creates PowerPoint slides
   • PPTX to PDF: Uses system tools (LibreOffice, unoconv) or Windows COM interface

💡 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
• Format Conversion Options:
  • PDF → PDF: Direct optimization for fastest processing
  • PPTX → PPTX: Maintains PowerPoint format while achieving target size
  • PDF → PPTX: Convert and optimize in one step (NEW!)
• Use the GUI for interactive file selection and real-time progress
• Use CLI for batch processing and automation
