🔐 Why Strip Metadata?

Images can contain hidden information:

• 📍 GPS coordinates - Where the photo was taken
• 📅 Timestamps - When it was taken
• 📱 Device info - Camera/phone model
• 👤 Author info - Your name, software used

This app removes all of that automatically.

Verify Metadata Removal

# Using exiftool
exiftool your_converted_image.png

# Should show minimal/no metadata
