The Mission: 100% In-Browser Execution
Every time you use a traditional "free online tool" to compress a JPG, remove a background, or convert an image, your file is quietly sent over the wire to a remote server. Many of those servers keep logs, store your photos, or inspect private EXIF metadata containing your satellite GPS location, device serial numbers, and camera timestamps.
MousyTools is built differently. We utilize client-side WebAssembly, the HTML5 Canvas API, Web Workers, and the WebCrypto API so that every calculation, pixel modification, and compression pass happens locally in your device's RAM.
Open your browser developer tools (F12) → go to the Network tab → drag a 50MB batch of photos into our tools. You will see 0 upload bytes. Nothing leaves your machine. It is impossible for us to see, store, or leak your images because we never receive them.
