Choose this when the cleaning needs to happen on the phone itself, which is where most oversharing actually occurs, right before you hit send. It’s open-source, MIT-licensed, and refreshingly simple. The limit is narrow format support, JPEG, PNG and WebP only, so it won’t touch video or other file types. As a pre-share habit on Android it does its one job cleanly, just don’t expect it to be your only metadata tool.
