Show HN: MetaStrip – Client-side metadata removal for photos, video, audio, docs
MetaStrip is a tool designed to remove metadata from various file types including photos, videos, audio, and documents. It addresses privacy concerns by eliminating sensitive information such as GPS coordinates and device serial numbers. The tool is particularly relevant in an era where sharing files can inadvertently expose personal data.
- ▪Photos can contain GPS coordinates and device serial numbers.
- ▪Documents like PDFs may include author names and edit histories.
- ▪AI-generated images often carry tags identifying the creation tool.
