No. All tools run entirely in your browser. Your images, numbers, and inputs never leave your device. We have no servers processing your data.

Which browsers are supported?

Latest Chrome, Edge, Firefox, and Safari. Image tools use WebGPU for best performance, with WebGL/WASM fallback. Finance and utility tools work in any modern browser.

Is there a file size or image size limit?
