Privacy

All image processing tools run entirely in your browser using the Canvas API, WebAssembly, and client-side JavaScript libraries. Your images are never uploaded to any server.

For AI tools (AI Rename, AI Alt Text, AI Organize), a small thumbnail is sent to Google Gemini for analysis. Full-resolution originals never leave your device and are never stored anywhere.
