Free QR Code Generator – Unlimited Custom QR Codes (No Signup)

No. QR Gen is completely free and requires no signup, no login, and no account. Everything works instantly in your browser — including adding logos and custom colors to your QR codes. Your data never leaves your device.

Yes. Unlike most QR code tools that lock logo uploads behind a paywall or login, QR Gen lets you add any logo or image to the center of your QR code for free. Upload your logo, adjust the size, and download — no account required.

Yes, QR Gen has a completely free QR code API. No API key, no authentication, no signup. Just make an HTTP GET or POST request and get back a PNG, SVG, or JSON response. CORS is enabled so you can call it from the browser too. See the developer docs for examples in Python, Node.js, curl, and Go.

Yes. QR Gen is designed to work with AI agents like ChatGPT, Claude, and other LLMs. The API requires no auth so any AI agent can call it directly. We also support MCP server integration, Claude Code, and OpenAI function calling. LLMs can even embed QR codes inline using the markdown image syntax: ![QR](https://qrgenapp.com/api/qr?data=hello)

Yes. QR Gen creates standard upi://pay format QR codes that work with every UPI app — Google Pay, PhonePe, Paytm, BHIM, and any other UPI-compatible app. You can create static QR codes (customer enters amount) or dynamic ones with a pre-filled amount.

The WiFi QR code generator creates a QR code that encodes your network name, password, and encryption type. When someone scans it with their phone camera, they connect to your WiFi automatically — no typing required. Works on both iPhone (iOS 11+) and Android. Perfect for cafes, coworking spaces, and home networks.

PNG, SVG, JPEG, and WEBP — all in high resolution. SVG is best for print (scales to any size without losing quality). PNG works everywhere. The API also supports a JSON format that returns the raw QR module matrix for custom rendering.

There is no catch. QR Gen is free, with no limits on the number of QR codes you can create. No watermarks, no expiring codes, no feature gates. The tool runs entirely in your browser, so there are minimal server costs. The API is free too.

Yes. QR Gen is a Progressive Web App (PWA). Install it from your browser and it works without an internet connection. QR codes are generated locally on your device, so offline mode works exactly the same as online mode.
