Free, Fast, and Completely Private Browser Tools
NT Tech builds practical free tools for content creators, stock photographers, marketers, and everyday users. Every tool on this page runs entirely in your browser — no file uploads to servers, no accounts, no subscriptions, and no hidden fees.
Whether you need to generate QR codes for a product launch, create SEO-optimized metadata for hundreds of stock images in minutes, or simply calculate your exact age for a document — NT Tech has a fast, reliable tool built exactly for that.
Your Files Never Leave Your Device
All NT Tech tools are built with a strict privacy-first philosophy. When you upload images to Metadata Studio, render AI or EPS vector files, or generate a QR code — every process happens locally inside your browser using JavaScript and WebAssembly.
No file is ever transmitted to NT Tech servers. The only external call Metadata Studio makes is to the Groq AI API using your own personal API key, which is stored only in your browser's local storage and never seen by NT Tech.
