What It Does

• Strip metadata from JPEG, PNG, PDF, Word, Excel, and PowerPoint files
• Concurrent processing with ThreadPoolExecutor handles 1000+ files efficiently
• Dry-run mode previews what would be removed before making changes
• Verification reports show before/after comparison of metadata fields
• Smart format detection uses file signatures, not extensions
• Removes GPS coordinates, author info, timestamps, camera data, and software traces
