Low preserves metadata; Medium attempts to remove app metadata; High also attempts to remove descriptive metadata. All use object streams. The smallest candidate or original is returned, so this tool does not guarantee metadata removal.
No. The tool works entirely in your web browser with no downloads or plugins needed. It runs on Chrome, Firefox, Safari, Edge, and mobile browsers.
