3. Adding watermark for brand protection: A photographer wants to share portfolio samples online with a subtle watermark. Image Resizer adds a semi-transparent logo to all images in one go.

Image Resizer 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.
• HTML5 APIs: The tool uses HTML5 APIs like File API for reading local files, Canvas API for image processing, and Web Workers for background thread processing to keep the interface responsive.
• No server dependency: Once the page loads, Image Resizer does not require an internet connection to function. All logic is contained within the downloaded JavaScript code.
• Memory management: The tool processes data in chunks when possible to avoid excessive memory usage. Large files are handled through streaming techniques where applicable.
