🎯 Why Metadata Cleaner?

The Problem

Every photo you take contains hidden information:

• 📍 GPS Coordinates - Exact location where the photo was taken
• 📷 Camera Details - Device model, lens information, camera settings
• 📅 Timestamps - When the photo was created and modified
• 👤 Author Information - User names and software details

This metadata can compromise your privacy when sharing files online.

The Solution

Metadata Cleaner removes all this sensitive information while preserving the quality of your files. Share photos, videos, and documents with confidence knowing your privacy is protected.
