About NT Tech Tools

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.

Privacy First Design

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.

🛡
Zero Data Collection
No accounts. No cookies. No analytics on tool usage. No file storage. Your data stays yours.
✓ No Sign-up ✓ No Upload ✓ Free Forever
FAQ

Frequently Asked Questions

Common questions about the NT Tech free tools collection.

Are all NT Tech tools really free?
+
Yes, completely free with no hidden costs. QR Studio and Age Calculator require no external accounts whatsoever. Metadata Studio uses the Groq AI API, which has a generous free tier — you bring your own free Groq API key and NT Tech never charges for the tool itself.
Do I need to create an account to use the tools?
+
No account is required for any tool. QR Studio and Age Calculator work with zero setup. Metadata Studio only requires you to paste your own free Groq API key — which stays in your browser and is never sent to NT Tech.
What does Metadata Studio do?
+
Metadata Studio is an AI-powered tool for stock content creators. Upload your images, vectors (including Adobe AI and EPS files), or videos and it generates SEO-optimized titles, keyword sets, and descriptions formatted for platforms like Adobe Stock, Shutterstock, Getty Images, Freepik, and more. Export everything as a CSV ready for bulk upload.
Can QR Studio generate QR codes with my logo?
+
Yes. QR Studio supports custom logo upload, full color customization including gradients, transparent background support, and high-resolution PNG download. All generation happens instantly in your browser with no server round-trip.
Will more tools be added to this page?
