How the QR Code Editor works
- Type or paste the text or URL you want the QR code to encode.
- Pick a foreground and background color, keeping enough contrast for scanners to read it.
- Choose square or rounded modules, then download the result as a PNG.
FAQ
Does this tool upload my data?
No. The QR code is generated entirely in your browser — the content you enter never leaves your device.
Why does it warn about color contrast?
QR scanners rely on a strong light/dark difference between modules and background. Colors that are too close in brightness can make the code unreadable, even though it looks fine on screen.
What's the difference between square and rounded modules?
Both encode the identical data — rounded modules just draw each dark square with rounded corners for a softer look. Scannability is unaffected either way.
Can I use it without an account?
Yes. There's no sign-up — enter your content and download the PNG directly.
