How it works
Learn about the technology behind secure metadata removal and privacy protection.
What is Metadata?
Metadata is hidden information embedded in files like photos, documents, and videos. It can include:
- EXIF data: Camera settings, date/time, software used
- GPS coordinates: Exact location where photo was taken
- Author information: Who created the file
- Device details: Camera model, serial numbers, software versions
- Comments and descriptions: User-added notes
