- • Reversible compression
- • Ideal for text documents
- • 30-50% size reduction
- • Professional archiving
Best for: Legal documents, contracts, technical manuals
📊 Lossy Compression
- • Higher compression ratios
- • Selective quality reduction
- • Optimized for images
- • 60-90% size reduction
- • Web-optimized output
Best for: Marketing materials, web documents, presentations
Advanced Compression Algorithms
🤖 AI-Powered Smart Compression
Modern AI algorithms analyze document content to apply optimal compression strategies:
- • Content Analysis: Identifies text, images, and graphics separately
- • Adaptive Quality: Applies different compression levels to different elements
- • Predictive Optimization: Learns from document patterns for better results
- • Quality Preservation: Maintains readability while maximizing compression
⚙️ Ghostscript Engine Optimization
Professional-grade compression using advanced Ghostscript parameters:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.7
-dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH
-dColorImageResolution=150 -dGrayImageResolution=150
-dMonoImageResolution=300 -dDownsampleColorImages=true- • Custom resolution settings for different image types
- • Optimized color space conversion
- • Font subsetting and embedding control
- • Advanced image downsampling algorithms
