About QRgenie

What QRgenie does

QRgenie is a straightforward tool: you give it a URL, a phone number, a Wi-Fi password, or any text you like — it gives you a QR code. You can customise the colours, choose between square and rounded modules, set the export resolution, and download the result as a PNG or a crisp vector SVG.

Every single step happens inside your browser. The QR algorithm runs in JavaScript on your device. Nothing you type is sent to any external server, stored in any database, or logged anywhere.

Why we built it

Most QR code generators on the web ask you to create an account before you can download a clean file, or they embed a watermark unless you pay, or they quietly send your link to a server so they can build analytics profiles. We found that frustrating and decided to build a better option.

QRgenie is part of RuntimeHub — a growing collection of browser-native tools built around the same principle: powerful utilities that respect your privacy, work without an internet connection once loaded, and never ask for more than they need to get the job done.

How it works technically

QR code generation is handled by an MIT-licensed JavaScript library that implements the QR Code specification entirely on the client side. The library converts your input into a matrix of dark and light modules, applies the error-correction algorithm you choose, and renders the result onto an HTML Canvas element. From there, PNG export is a single Canvas API call. SVG export rebuilds the same module matrix as a compact vector file — no fonts, no external assets, fully self-contained.

There are no cookies, no analytics scripts, and no third-party trackers on this page beyond the Google Fonts CDN used to load the typeface.

What QRgenie is not

QRgenie generates static QR codes. The destination is encoded directly into the pattern — it cannot be changed after the code is printed. If you need dynamic codes that can be redirected without reprinting, you will want a service that hosts a short URL on your behalf. QRgenie does not offer that, by design: there is no server, no database, and no redirect infrastructure.

Free, always

No paid tier, no watermark removal fee, no generation limit. QRgenie is free for personal and commercial use with no strings attached.

Private, by architecture

Client-side generation means there is no server to send your data to. Your URLs stay on your device — full stop.

Open formats

PNG and SVG are universal. Your exports work in every design tool, print workflow, and presentation app without conversion.

The RuntimeHub philosophy

RuntimeHub tools share a few hard rules: no mandatory accounts, no upload of your data to process it, no dark patterns around pricing. Tools are monetised by non-intrusive advertising, never by harvesting user data. The code runs in the browser and the browser alone.

If you find QRgenie useful, the best thing you can do is share it with someone who needs it, or explore the other tools at runtime-hub.com.
