ℹ️ How Compression Works:
- Light: Removes metadata only (~5-10% reduction)
- Standard: Metadata removal + object stream compression (~10-20% reduction)
- Maximum: Aggressive optimization (~15-30% reduction)
- Works best on PDFs with bloated metadata or unoptimized structure

💡 Tips:
- Start with Standard compression for best balance
- Try different levels - you can re-compress without re-uploading

- Already-compressed PDFs may not compress further
- Password-protected PDFs must be unlocked first
