How PDF compression works:
- • Images inside the PDF are re-compressed at the selected quality level
- • Higher quality = larger file, better appearance
- • Lower quality = smaller file, slightly reduced image quality
- • Text and vector graphics remain crisp at any compression level
🔒 All processing happens in your browser - your files are never uploaded.
