MetaPurge is a privacy-first utility for locally stripping sensitive EXIF and metadata from your photos. Unlike other apps that just 'hide' tags, MetaPurge uses a 'nuclear' approach—it physically cuts the metadata segments out of the file bytes. Key Features: • 100% Offline: Your photos never leave your device. • Zero Permissions: No storage or internet permissions required on modern Android. • Format Support: JPEG, PNG, and WebP. • Smart Tools: Automatic orientation correction and high-res photo handling. • Transparent: Full technical metadata view for expert users. Keep your pixels, lose the tracking.

Protect your privacy by removing metadata from your photos, before sharing them on the Internet. Features: ✔️ View metadata ✔️ Image preview ✔️ Remove metadata ✔️ Simple and intuitive interface ✔️ Share directly from the app Learn more: Whenever you take a picture, additional metadata is saved in the image file. Most smartphones do not inform you about this. Metadata can look like this: 🕑 On which day was the picture taken, and at what time? 🗺️ And where exactly? 📷 Which camera or smartphone was used? 🔧 What camera settings were used? 📝 Notes of the photographer or the camera? 📌 More and more often, even exact GPS coordinates are saved in your photo. Metadata is sometimes very useful — for instance when sorting holiday photos. As soon as you share photos with others via social media, all this info is visible publicly. Data collectors and stalkers are more easily able to discover your place of residence or workplace from the metadata or draw conclusions about your daily routine. Tracking services create more comprehensive advertising profiles and sell your data to other organizations. Use the Metadata Remover to easily view all that data, remove it entirely, and then share the anonymized photo directly! That way you stay anonymous and safe on the Internet, while your friends can still admire your cute cat. Happy sharing! 😽
