About QR Code Generation

Why generate QR codes locally?

Most QR code generators send your data to their servers. I built this one to avoid that. Your URL, text, or WiFi credentials never leave your browser.

This matters most for WiFi credentials. You do not want your network password logged on some server.

No server

Everything runs in your browser tab

Your data stays here

Nothing is transmitted or stored

Custom styling

Colors, dot patterns, logo overlay

Batch export

Download multiple codes as ZIP

What you can encode

This tool handles the formats I get asked about most:

Website URLs — share links that open directly in browser
Plain text — notes, poems, whatever you need
Email addresses — tap to compose on mobile
Phone numbers — tap to call
WiFi network info — scan and connect, no typing

WiFi QR codes

I use this most for sharing home WiFi with guests. Enter your network name, password, and encryption type. WPA/WPA2 is the most common setting. Guests scan once and they are connected.

Works on iOS Camera app and most Android QR scanner apps. Hidden networks work too, though some older phones have trouble with those.

Styling options

You can customize colors to match your brand or event. The dot pattern option uses circles instead of squares—it tends to look better on print materials. Logo overlay is available if you need to brand your codes.

Practical tip

For print, aim for 400px or larger. Test with your phone camera before ordering 1000 stickers.

Batch mode

If you need many codes for event badges or product labels, paste a list of URLs and download all at once as a ZIP. Each code is generated separately at full resolution.

Export formats

SVG for vectors, PNG for raster, WebP for smaller web files.

SVG — vector format, scales to any size without blur
PNG — raster format, use for digital or print under 300dpi
WebP — smaller file size, good for web

Common questions

Can I use this for commercial projects? Yes. QR codes themselves are public domain. Do whatever you need.

How much can I encode? Theoretically 4,296 characters. In practice, keep it under 500 for reliable scanning on most phones.

My QR code will not scan Usually it is size (too small) or contrast (not enough difference between dark and light modules). Try increasing the output size first.

Does it work offline? Yes. After the page loads, the JavaScript runs entirely in your browser with no network requests.
