How It Works
Every tool runs directly in your browser. Here's the technical breakdown.
You Open a Tool
When you visit any tool page, the JavaScript and WebAssembly code is loaded into your browser. This is the only network request.
Processing Happens Locally
Your input (text, code, files) is processed entirely by your browser's JavaScript engine. No data is sent to any server. You can verify this in your browser's Network tab.
Results Stay on Your Device
Output is displayed immediately. If you save anything, it goes to your browser's local storage (IndexedDB or localStorage) — never to an external database.
Export Anytime
Download your results as files. The download is generated locally. Even the export process makes zero network requests.
