Technical Architecture & Local Privacy

HelpMyIMG was born out of this necessity. By leveraging cutting-edge WebAssembly (Wasm) and WebGL/WebGPU technologies, we successfully ported complex Machine Learning models directly into the web browser.

WebAssembly (Wasm)

We compile heavy machine learning frameworks like ONNX Runtime directly into Wasm, allowing them to run at near-native speeds right inside your browser engine.

Zero Tracking

Unlike 99% of AI tools on the market, HelpMyIMG processes your images LOCALLY. We do NOT upload, store, view, or train our AI models on your photos. Your data never leaves your computer.

Lightning Fast

0ms network latency after initial model load.

FAQ

Everything you need to know about our privacy-first AI tools, limits, formats, and how they work directly in your browser.

Does this tool automatically detect my face?

Yes, you can manually adjust the crop box to ensure your head meets the 70-80% frame coverage required by most countries.

Can it change my background to white or blue?

Absolutely! Since this is an all-in-one suite, you can use the 'Change Background' tool right after resizing to get a perfect white or blue backdrop.

What resolution does it export?

We export at a high 300 DPI resolution, which is required for printing passport photos at pharmacies or print shops.
