Currency Converter leverages modern browser technologies to deliver professional-grade processing entirely on your device. Here is how it works under the hood:

• JavaScript engines: Modern browsers include highly optimized JavaScript engines (V8 in Chrome, SpiderMonkey in Firefox, JavaScriptCore in Safari) that execute the tool's processing algorithms at near-native speed.
• WebAssembly: For computationally intensive tasks, the tool may use WebAssembly (Wasm) to run compiled code in the browser at speeds comparable to desktop applications.
